  31st October

Today's clear skies and pleasant sunshine were somewhat tempered by a raw north-east wind although the latter was no doubt the main factor in really bucking up the birding. Most of the arrivals at the Bill were struggling in off the sea and heading away into the wind, with the morning returning totals of 375 Starlings, 250 Chaffinches, 100 Blackbirds, 80 Redwings, 30 Song Thrushes, 25 Fieldfares, 11 Lapwings, 10 Goldcrests, 7 Bramblings, 6 Long-tailed Tits, 3 Chiffchaffs, 3 Redpolls, 2 Blackcaps, a Grey Heron, a Woodcock, a Swallow, a Wheatear and a Firecrest; 30 Brent Geese also passed though on the sea there. Noteworthy reports from elsewhere included the Yellow-browed Warbler still at Reforne, a Firecrest at Pennsylvania Castle and a Hen Harrier heading north over Perryfields.

  30th October

Quite disappointing today with some really interesting-looking weather conditions - a blasting easterly and heavy rain lingering on into the morning - failing to produce the goods. Plenty of Starlings - including a minimum of 700 at the Bill - were arriving in off the sea through the morning and several dozen Redwings were swirling around in the rain but otherwise the best of the day's reports were of 4 Long-tailed Tits, 3 Lapwings, 2 Black Redstarts, a Purple Sandpiper, a Mistle Thrush and a Firecrest at the Bill, 2 Firecrests at Delhi Lane, 2 Black Redstarts at Reap Lane and 5 Fieldfares and 2 Pale-bellied Brent Geese at Ferrybridge. Eight Brent Geese and singles of Red-throated Diver, Great Northern Diver and Mediterranean Gull passed thorough on the sea at the Bill.

  29th October

Dawn saw the first frost of the autumn after another very clear night and there was again a small flurry of new arrivals; these continued as the day went on with the afternoon seeing the arrival of quite a few new thrushes that dropped in under the increasing cloud associated with wind and rain that rolled in after dark. The Bill area produced tardy singles of Garden Warbler and Pied Flycatcher, along with 60 Redwings, 30 Blackbirds, 20 Song Thrushes, 20 Siskins, 9 Swallows, 7 Blackcaps, 7 Bramblings, 6 Chiffchaffs, 6 Goldcrests, 4 Redpolls, 4 Reed Buntings, 3 Snipe, 2 Fieldfares, a Great Northern Diver, a Lapwing, a Curlew, a Short-eared Owl, a Black Redstart and a Firecrest. News from elsewhere included a Yellow-browed Warbler at Easton and 42 Mediterranean Gulls, 2 Wigeon, a Pale-bellied Brent Goose and a Knot at Ferrybridge.

Despite the chilly conditions there were still a few immigrant moths on the wing, with the Obs garden traps producing 7 Silver Y, 2 Pearly Underwing, a Rush Veneer and a White-speck.

  28th October

Fresh northerlies and clear skies saw to it that there was a real nip in the air at dawn and a very minor flurry of Redwings showed up (moaning about something yesterday did some good after all). Most of the news came from the Bill area where there were 20 Redwings, 10 Siskins, 4 Lapwings, 4 Black Redstarts, 4 Bramblings, 4 Reed Buntings, 3 Short-eared Owls, 2 Swallows, 2 Redpolls, a Great Northern Diver, a Snipe and a Firecrest, along with a sprinkle of new Blackbirds, Song Thrushes and Goldcrests; rather surprisingly there was no really concerted movement overhead on the sort of morning that looked good for some pigeon passage or the like. The only other news was of a lone Pale-bellied Brent Goose at Ferrybridge.

27th October

The recent migration hiatus continued and it remained very much quieter than it ought to be at this time of the autumn (we keep hearing of, for example, large movements of thrushes and the like in other parts of the country but these things just aren't getting over to this part of the world at the moment). Most of what movement there was today was overhead, with 200 Wood Pigeons, 25 Siskins, 12 Reed Buntings, 11 Swallows and 4 Redpolls the best of some light passage at the Bill where a lot of birds were high enough to be out of audible range and so tricky to identify. The pretty dreadful selection on the ground at the Bill included singles of Short-eared Owl, Black Redstart and Firecrest, all of which appeared to be lingering on from previous days, as was the Grey Phalarope that was still at Chesil Cove; 2 more Black Redstarts were also at the Cove.

Immigrant interest in the Obs garden moth-traps this morning consisted of 11 Silver Y, 3 Rusty-dot Pearl, 2 Rush Veneer and 2 White-speck.

26th October

Despite a real dose of overnight wind and rain there were a few new arrivals about today although getting to grips with them was never easy as the rain took an age to clear through. A Grey Phalarope that lingered for a while in Chesil Cove was the best of the sightings; a late Arctic Tern was also there and a Shelduck and a Great Skua passed through off the Bill. On the land 4 Black Redstarts, 2 Firecrests and a Short-eared Owl were the pick of the birds at the Bill where a few new arrivals, including 3 Blackcaps, were netted once the rain eased during the afternoon.

Eight Rusty-dot Pearl, 2 Rush Veneer and a Silver Y were the only immigrants in the single moth-trap operated overnight in the Obs garden.

Late news for yesterday: a Crossbill passed overhead at Reap Lane and 1, possibly 2, Sabine's Gulls were reported by visiting seawatchers.

...a photo that has no significance - although we do quite like it - other than it allows us to vent our frustration at not being able to get a single meaningful image of a silent, lurking acro that only showed for milliseconds at a time in the same dense ivy bush  (we were nearly sure it was a Reed Warbler, but you never quite know at this time of year...). Needless to say, the one image obtained of the Chiffchaff shows only a tenth of the bird but allows it to be identified in an instant!

  25th October

A longer list of sightings today although all the numbers were overhead rather than on the ground. Finches in particular were on the move in good numbers, with a short sample count at the Bill producing 370 Linnets, 125 Goldfinches, 120 Meadow Pipits, 21 Wood Pigeons, 21 Skylarks and 18 Chaffinches; lots more of the same were on move at other times along with 10 Siskins, 4 Bramblings and the first Fieldfare of the autumn. Two Black Redstarts, a Merlin and a new Firecrest were the best of the scarcer species on the ground at the Bill. A freshening wind didn't perk things up on the sea, with singles of Manx Shearwater and Great Skua providing the only interest off the Bill.

Immigrants in the Obs garden moth-traps this morning: 27 Rusty-dot Pearl, 3 Rush Veneer, 3 Silver Y and 2 Pearly Underwing.

24th October

With the weather having calmed down again there was decent coverage of the land which did little more than reveal how few new arrivals there were. The only particularly worthwhile sightings were of 5 Siskins, 3 Black Redstarts, a Short-eared Owl, a Firecrest and a Redpoll at the Bill, a Ring Ouzel at Southwell and another 2 Firecrests at Church Ope Cove. Seawatching at the Bill produced singles of Great Northern Diver, Great Skua and Mediterranean Gull.

Eight Rusty-dot Pearl, a Delicate and a Clancy's Rustic were the only immigrant moths in the Obs garden traps this morning.

  23rd October

A freshening south-westerly saw most attention return to the sea, with totals of 29 Common Scoter, 16 Balearic Shearwaters, 10 Sooty Shearwaters, 2 Red-breasted Mergansers, 2 Great Skuas and a Manx Shearwater logged at the Bill. The only reports from the land at the Bill were of singles of Merlin, Purple Sandpiper, Firecrest and Siskin.

A minor improvement in moth numbers in the Obs garden traps included an overnight immigrant tally of 35 Rusty-dot Pearl, 8 Silver Y, 7 Rush Veneer, 3 White-speck and 2 Pearly Underwing, along with some local interest in the form of a single specimen of the gorse-feeder Agonopterix umbellana (of which the only other island record is of 2 at the Obs on 1st October 1994).

22nd October

Totally uninspiring conditions - blustery, crystal-clear westerlies - and a pretty uninspiring bird list today. Routine passage on the land dwindled to such an extent that only 4 new birds were trapped and ringed at the Obs all day, and the only faintly interesting sightings at the Bill were of 25 Siskins, 3 Turnstones, 2 Firecrests, a Merlin, a Golden Plover, a Black Redstart and a Redpoll. Elsewhere there was another a Firecrest at Church Ope Cove and a Lesser Whitethroat at Southwell.

The conditions were as poor for moths as they were for birds, with the only immigrants in the Obs garden moth-traps this morning being 11 Silver Y, 9 Rusty-dot Pearl, 2 Rush Veneer and singles of Pearly Underwing and White-speck.

 

   

  

  

  

  Stonechat, Garden Warbler and something that ought by rights to have been an American Painted Lady but unfortunately was just another regulation Painted Lady - Portland Bill, 21st October 2008 © Martin Cade

...the Garden Warbler is a long-stayer that's clearly thriving: its weight had increased from 18.7gm when first caught on 15th October to 26.2gm when retrapped today.

  21st October

With the overnight wind and rain having taken way too long to have cleared through there was little opportunity for migrants to have got moving and new arrivals were again at a premium. Odds and ends at the Bill included 20 Siskins, 3 Turnstones, 3 Black Redstarts, 3 Wheatears, 2 Blackcaps, 2 Redpolls, 2 Reed Buntings, a Short-eared Owl, a Ring Ouzel, a Garden Warbler and a Firecrest.

At least 1 Painted Lady was in the Obs garden.

There were very few immigrants in the Obs garden moth-traps this morning: 15 Rusty-dot Pearl, 2 Silver Y and a Clancy's Rustic.

Late news for yesterday: a Little Gull was an addition to the seawatch tally at Chesil Cove.

20th October

Whilst there was considerably less rain than forecast until well into the afternoon it remained dreary and windy throughout and nearly all the news was of seawatching, which produced 11 Common Scoter, 5 Balearic Shearwaters, 5 Great Skuas, a Pomarine Skua and an Arctic Skua off the Bill and singles of Manx Shearwater and Great Skua off Chesil Cove. The only other reports were of single Black Redstarts at the Bill and Reap Lane.

The immigrant tally in the Obs garden moth-traps this morning consisted of 24 Rusty-dot Pearl and singles of White-speck, Clancy's Rustic and Silver Y.

  19th October

A good deal of coverage of the land revealed nothing much more than 3 Siskins, 2 Black Restarts, a Snipe and a Ring Ouzel amongst the very small numbers of commoner migrants at the Bill; elsewhere there was another Ring Ouzel at Barleycrates Lane. Quite a bit of attention was also given to the sea, with the Bill producing 25 Common Scoter, 4 Balearic Shearwaters and singles of Great Northern Diver, Great Crested Grebe and Manx Shearwater.

The first Painted Lady for some while was in the Obs garden, where yet another Western Conifer Seed Bug was also discovered.

Immigrants in the Obs garden moth-traps this morning consisted of 48 Rusty-dot Pearl, 4 Silver Y and 2 each of Delicate and Dark Spectacle.

18th October

Poor reward again today with few oddities, precious little grounded and surprisingly little on the move overhead. The only scarcer migrants reported were 3 Bramblings and singles of Merlin, Short-eared Owl, Black Redstart and Firecrest at the Bill where there was otherwise little worth reporting by way of numbers or variety of commoner species. A single Balearic Shearwater passed through on the sea at the Bill.

Another Western Conifer Seed Bug was found at the Obs this morning.

Immigrant numbers picked up a little in the Obs garden moth-traps: 70 Rusty-dot Pearl 10 Silver Y, 3 Delicate, a Dark Sword Grass and a Clancy's Rustic.

 

   

   

   Treecreeper and Jackdaw - Portland Bill, 17th October 2008 © Martin Cade

  17th October

A lovely clear, still day to be out birding but, the usual suspects aside, there still wasn't too much to be seen, with what oddities there were - namely a Yellow-browed Warbler at Wakeham and a Treecreeper trapped and ringed at the Obs - only providing interest at a relatively local level. The supporting cast included 2 Firecrests, a Merlin, a Short-eared Owl, a Ring Ouzel and a Dartford Warbler at the Bill, where 50 Goldcrests made up the bulk of the new arrivals on the ground and 44 Jackdaws, 35 Siskins, 20 Redpolls, 15 Reed Buntings, 4 Bramblings (click here to listen to a short recording of one of these birds calling from a treetop at the Obs), 2 Snipe and a Lapwing were the best of the birds on the move overhead.

Moths were not at all plentiful in cool conditions overnight and 11 Silver Y, 5 Rusty-dot Pearl and a lone Delicate were the only immigrants attracted to the Obs garden traps.

16th October

Despite a gradual improvement in the weather there wasn't too much to be seen by way of common migrants although a Hawfinch at Penn's Weare, a Ring Ouzel at Barleycrates Lane and singles of Black Redstart and Firecrest at the Bill did provide some interest. Commoner migrants were very thinly spread on the ground but a little more on the move overhead included 300 Linnets, 150 alba wagtails, 100 Chaffinches, 70 Starlings and 60 Goldfinches at the Bill; singles of Merlin, Golden Plover, Short-eared Owl and Garden Warbler were about the only other noteworthy sightings on the ground at the Bill, where a lone Arctic Skua also passed though on the sea.

As on the last few sunny days there was again some evidence of presumed emigration of Red Admiral butterflies today, with many individuals watched moving purposefully from north to south at the Bill.

In cool and breezy conditions overnight the only immigrants attracted to the Obs garden moth-traps were 11 Rusty-dot Pearl, 9 Silver Y, a Pearly Underwing, a White-speck and a Clancy's Rustic.

Late news for last Saturday night/Sunday morning (11th/12th): a Western Conifer Seed Bug was attracted to one of the moth-traps operated overnight by visiting moth-trappers at Cheyne Weare.

15th October

Grey skies, a brisk westerly wind and a few early showers weren't the sort of conditions to enthuse anyone but a few oddities did still show up, notably a brief Yellow-browed Warbler in a private garden at Southwell, a Woodlark in Top Fields and a Dartford Warbler at Barleycrates Lane. Two Black Redstarts and a Firecrest were still at the Bill, late singles of Reed Warbler and Garden Warbler were new arrivals there and single Merlins were at both Barleycrates Lane and Verne Common but commoner migrants were pretty few and far between. 

Immigrants in the Obs garden moth-traps this morning included 43 Rusty-dot Pearl, 19 Silver Y, 2 Delicate and singles of Vestal, White-speck and Clancy's Rustic.

Late news for yesterday: 2 Pintail passed through off the Bill.

  14th October

Less overhead and not too much on the ground today. The only out of the ordinary sightings involved a family party of 5 Pale-bellied Brent Geese that dropped in on the shore along the East Cliffs at the Bill and 2 Continental Coal Tits at Wakeham. Fifty Siskins, 2 Merlins, 2 Short-eared Owls, 2 Black Redstarts, 2 Firecrests and late singles of Yellow Wagtail and Reed Warbler were the pick of the commoner migrants at the Bill.

In very good moth-trapping conditions overnight the immigrant list in the Obs garden traps consisted of 125 Rusty-dot Pearl, 34 Silver Y, 5 Vestal, 4 Clancy's Rustic, 2 Diamond-back Moth, 2 Rush Veneer, 2 Four-spotted Footman and 2 Delicate.

Finally, we've been very slow on the uptake regarding the identification of a peculiar large bug discovered on the Obs patio yesterday. We've just realised today that it's a specimen of the Western Conifer Seed Bug Leptoglossus occidentalis, a North American species that was accidentally introduced into Europe in 1999 and first reached Britain in 2007 (the first specimen was found at Weymouth College by Obs member Bob Ford, and subsequently the species has been recorded at several sites in south-east England this autumn).

13th October

The return of overcast skies didn't produce much in the way of grounded migrants but did lead to one of the better 'non-hirundine' overhead movements of the autumn. At the Bill most movement was southward along/off the East Cliffs, with a 2 hour sample count producing totals that included 1415 Linnets, 533 alba wagtails, 525 Goldfinches, 490 Meadow Pipits, 185 Swallows, 104 Siskins, 46 Skylarks, 19 Chaffinches and 3 Merlins. The land produced a light scatter of October staples such as Chiffchaffs and Goldcrests everywhere, with minor interest provided by the likes of 3 Black Redstarts, 2 Redwings, a Water Rail and a Golden Plover at the Bill and a Grasshopper Warbler at Perryfields.

There wasn't too much change in the Obs garden moth-traps, with the overnight immigrant tally consisting of 106 Rusty-dot Pearl, 5 Silver Y, 4 Clancy's Rustic, 2 Four-spotted Footman, 2 Delicate and a Palpita vitrealis.

12th October

Dense fog that rolled in shortly after dawn spoilt the morning's birding and by the time it cleared a few hours later most birders had jacked in for the day. What little coverage there was revealed 4 Short-eared Owls and singles of Merlin, Snipe, Redwing and Firecrest at the Bill and singles of Redwing and Garden Warbler in the Easton/Grove area; commoner migrants were only thinly spread and there was practically no overhead passage other than the trickle of hirundines that going once the fog cleared.

The immigrant moth tally from the Obs garden traps was similar to yesterday: 81 Rusty-dot Pearl, 2 Delicate, 2 Silver Y, a Rush Veneer, a European Corn-borer and a Clancy's Rustic; visiting moth-trappers working the Cheyne Weare area overnight logged a similar list, along with a single Flame Brocade.

11th October

Another lovely day to be out birding but probably too nice to be very productive. Most of what movement there was was overhead, with a sample 90 minute count at the Bill producing 240 Linnets, 180 alba wagtails, 94 Skylarks, 38 Siskins, 7 Chaffinches, 4 Grey Wagtails, 4 Reed Buntings, a Brambling and a Redpoll; singles of Little Egret and Osprey also passed over at the Bill at other times. It remained pretty deadly on the ground, with the best that could be mustered from the Bill area being 4 Short-eared Owls, 2 Merlins, a Snipe, the first Black Redstart of the autumn and a Yellowhammer, whilst a Great Spotted Woodpecker showed up at Verne Common and a Turtle Dove was at Easton. The only news from the sea was of 8 Mediterranean Gulls, 3 Sanderling and a Balearic Shearwater passing through off the Bill.

Overnight mothing at the Obs produced 85 Rusty-dot Pearl, 4 Clancy's Rustic, 2 Silver Y and a Delicate.

  10th October

Fair weather again but precious little by way of quality or quantity today. Two Short-eared Owls, a Merlin and a Woodlark provided just about the only interest at the Bill where commoner migrants were reduced to little more than ones and twos of the most routine species on the ground and nothing in any great numbers overhead. Seawatching at the Bill produced 3 Arctic Skuas, 2 Little Egrets, 2 Great Skuas, 2 Puffins and a Manx Shearwater.

9th October

No sign today of the Grey-cheeked Thrush. Under an almost cloudless sky it was something of a surprise to get a decent arrival of new Goldcrests, that included a good 200 or so in the Bill area, but otherwise grounded migrants were restricted to small numbers of the usual early October fare that included singles of Merlin, Water Rail, Short-eared Owl and Firecrest at the Bill; single Yellow-browed Warblers at Easton and Verne Common were the only goodies discovered elsewhere. There was plenty of movement overhead although in nothing more than a light breeze birds seemed to be heading in all directions; all the usual hirundines, wagtails, finches etc were well represented without there being any particularly noteworthy numbers or species. The only reports from the sea were of 25 Common Scoter and singles of Great Northern Diver and Great Skua passing the Bill.

Another small overnight catch of immigrants in the Obs garden moth-traps included 33 Rusty-dot Pearl, 6 Silver Y, 2 Dark Sword Grass, a Delicate and a Clancy's Rustic.

Late news for yesterday: we forgot to mention a Bearded Tit that dropped in briefly near the Admiralty hedge at the Bill and 5 Great Skuas that passed through on the sea there.

...and we may as well bore you with some more thrush pictures: the outdoor photos above were taken in very strong sunlight and perhaps wash out the colour tones a bit too much; the two head shots below were taken indoors and give a better idea of the true colouration:

  

  

...several observers commented on the age of the bird as pale tips to the greater coverts weren't at all apparent at most angles; as the photo below shows they were present when you got the light/angle right and the moult-limit between these pale tipped outer feathers and the uniform inner feathers clearly established the age as being first-winter:

  

...and finally some incidental pictures of the bird on show in the hand, being photographed and about to be released in the Obs Quarry:

  8th October

Portland's share of the Nearctic bonanza deposited in south-west England and Ireland in the aftermath of tropical storm Laura turned up today when Portland and Dorset's first Grey-cheeked Thrush was trapped and ringed at the Obs early in the afternoon; the bird showed well for half an hour after release but thereafter afforded just a few mainly fleeting flight views in the last hour of daylight. In glorious sunshine commoner migrants were very thinly spread on the land but there was quite a bit of passage overhead. The Bill area received pretty well all the attention: singles of Merlin, Whinchat and Reed Warbler provided just about the only interest on the ground, whilst a sample 90 minute count of overhead passage produced 780 Meadow Pipits, 319 alba wagtails, 290 Swallows, 135 Linnets, 110 House Martins, 70 Goldfinches, 32 Chaffinches, 14 Skylarks, 6 Siskins, 2 Reed Buntings and a Tree Pipit.

7th October

Another southerly blow saw to it that all eyes were on the sea again today but, a good Great Skua tally aside, the reward for the hours spent watching was not too great. The day's totals for the Bill were 46 Great Skuas, 25 Common Scoter, 6 Balearic Shearwaters, 6 Arctic Skuas, 6 Sooty Shearwaters, 2 Pomarine Skuas, a Little Gull and a Sandwich Tern. Full totals aren't available yet for Chesil Cove but a short watch in the late morning produced 5 Arctic Terns, 2 Balearic Shearwaters and 2 Sooty Shearwaters.

The Obs garden moth-traps produced more of the same, with the overnight immigrant tally consisting of 53 Rusty-dot Pearl and 16 Silver Y.

 

   

  

  

       

   Merlin and Grey Phalarope - Portland Bill, 6th October 2008 © Martin Cade

  6th October

For the most part a pleasantly still and overcast day with plenty of opportunity for decent coverage of the land for the first time for a few days. The only unexpected find was a freshly dead Grey Phalarope that was brought to the Obs by a member of the public who'd found it underneath a bench near the Bill lighthouse. The Bill area got most of the attention and returned totals that included 50 each of Chiffchaff and Goldcrest, 20 Stonechats, 15 Blackcaps, 10 Song Thrushes, 3 Little Egrets, 3 Reed Buntings, 2 Merlins, 2 Wheatears, 2 Garden Warblers, a Golden Plover, a Yellow Wagtail, a Redstart, a Redwing, a Reed Warbler, a Willow Warbler, a Firecrest and a Brambling; relatively small numbers of hirundines and Linnets also passed though overhead. A late Pied Flycatcher at Tout Quarry was about the best of the sightings from elsewhere. Sea passage died right away but did still include 45 Common Scoter, 6 Balearic Shearwaters, 5 Mediterranean Gulls, 2 Great Skuas and a Manx Shearwater passing through off the Bill.

There was a big increase in immigrant numbers - although certainly not in variety - in the Obs garden moth-traps this morning: 142 Rusty-dot Pearl and 12 Silver Y.

5th October

Another stormy and wet night/early morning but not nearly so much on the move off the Bill. The morning's totals for the two main watchpoints included 28 Great Skuas, 20 Common Scoter, 11 Mediterranean Gulls, 10 Arctic Skuas, 6 Manx Shearwaters, 5 Balearic Shearwaters and 2 Sooty Shearwaters passing the Bill and 3 Mediterranean Gulls, 2 Manx Shearwaters, a Great Skua, a Sabine's Gull, a Little Gull and a Grey Phalarope passing/lingering at Chesil Cove. Once the worst of the weather cleared through there were fair numbers of Swallows on the move at the Bill, where the land otherwise produced just small numbers of Chiffchaffs and Goldcrests and a lone Short-eared Owl.

  4th October

A fairish couple of hours at the start of the day provided a short window of opportunity to have a look on the land but before long the wind freshened from the south-west and it became increasingly stormy and wet as the afternoon went on. Quite a bit of Linnet movement was evident overhead although most of the 500 or so that passed over the Bill seemed to chicken out of actually leaving out to sea; 4 Wheatears, 2 Merlins, 2 Grey Wagtails, 2 Siskins and small numbers of Blackcaps, Chiffchaffs and Goldcrests were also there. Sea passage started to pick up off the Bill through the morning and by late afternoon there had been totals that included 32 Arctic Skuas, 25 Common Scoter, 18 Sooty Shearwaters, 16 Manx Shearwaters, 15 Great Skuas, 11 Balearic Shearwaters, 4 Arctic Terns, 2 Fulmars, a Sabine's Gull and a Mediterranean Gull. Elsewhere, Chesil Cove produced several Arctic Skuas, 3 Grey Phalaropes and 4 probable Long-tailed Skuas, whilst 2 Arctic Skuas and an Arctic Tern passed through at Ferrybridge and 2 Little Stints were settled there.

3rd October

The slow start to October continued with the north/north-westerly wind having freshened up again. Grounded migrants included small numbers of Blackcaps, Chiffchaffs and Goldcrests in all the sheltered spots, 250 Pied Wagtails, 8 Wheatears, 3 Yellow Wagtails, a Short-eared Owl, a Whinchat and a Spotted Flycatcher at the Bill and a Firecrest at Wakeham, whilst 15 Siskins and a Woodlark were the pick of the birds on the move overhead at the Bill. The only news from the sea was of 5 Mediterranean Gulls passing through off the Bill.

Two Silver Y were the only immigrants in the otherwise very nearly empty Obs garden moth-traps.

 

2007 Annual Report update. We always seem to have been too busy with visitors/birds/website etc this year to be able to quite finish the report but are finally nearly there! Apologies to our members for what will be a much later publication date than usual but you'll be receiving the report with our autumn newsletter.

 

2nd October

A fairer day once a few hefty showers had passed though during the first hour of daylight. It remained relatively quiet on the ground but there was a good deal more on the move overhead, with a 75 minute early morning watch at the Bill producing 560 Meadow Pipits, 148 Linnets, 93 alba wagtails, 16 Swallows, 16 Chaffinches, 5 Siskins, 2 Merlins and a Yellow Wagtail; hirundines got moving in better numbers as the day went on when another 30 Siskins, 3 Grey Wagtails, a Great Spotted Woodpecker and a Reed Bunting also passed over. Nothing of particular importance was reported from the land but 4 Balearic Shearwaters and 4 Mediterranean Gulls passed through on the sea at the Bill.

A lone Rusty-dot Pearl was the only immigrant in the Obs garden moth-traps this morning.

  1st October

The strong north-westerly kept up all day although it was much sunnier than yesterday. The sheltered spots again held a few common migrants including, for example, 24 Blackcaps, 16 Chiffchaffs, 14 Goldcrests, 2 Garden Warblers and a Willow Warbler at Penn's Weare, and there was again at least 1 Merlin at the Bill.

Four Rusty-dot Pearl, 2 Silver Y and a Dark Spectacle were the only immigrants in the Obs garden moth-traps this morning.

    Nightjar - Portland Bill, probably 1st May 1960 © John Ash

...as it was a quiet day on the bird front we thought we'd post this wonderful old photograph from the archives. Perhaps rather surprisingly, last Sunday's Nightjar was only the third ever to have been trapped and ringed at Portland and we remembered that some years ago John Ash, one of the early pioneers of Portland ornithology, had given us this undated photograph of an in-hand Nightjar at the Bill. Assuming that the bird depicted was alive (it certainly looks as though it was alive but there are a couple of records of Nightjars being picked up dead in the 1950s so it's just possible the picture is of one of those birds) then the photograph was taken on 1st May 1960 and shows the first Nightjar to be ringed at Portland; evidently the bird flew into the Obs kitchen and was caught by hand! The dilapidated state of the Lower Lighthouse dates the picture to before summer 1960 and the only other Nightjar ringed at Portland was netted in the Coastguards garden in September 1960. There probably aren't too many photographs from this era that still survive but if any visitors to the website do posses archive photographs such as this then we'd love to see them.

  30th September

The arrival of quite stormy, westerly/north-westerly weather brought an end to our recent Indian summer and certainly knocked migrant interest on the head. Dribs and drabs of left-overs on the land included a few Blackcaps, Chiffchaffs and Goldcrests in sheltered spots but, with the exception of a Merlin at the Bill, there was otherwise precious little of any interest. The seawatchers were able to dust off their 'scopes for the first time in nearly three weeks but got no reward whatsoever at either Chesil Cove or the Bill.

  29th September

Another reasonable arrival of migrants today included singles of Great Spotted Woodpecker, Woodlark and Yellow-browed Warbler at the Bill and another Yellow-browed Warbler at Avalanche Road. Among the commoner species all the usual suspects were represented, albeit in generally slightly lower numbers than yesterday, with 35 Siskins, 9 Short-eared Owls, 4 Redpolls, 2 Firecrests, a Merlin, a Snipe, a Golden Plover, a Pied Flycatcher and a Crossbill providing interest at the Bill.

Immigrant-wise it was a little better in the Obs garden moth-traps this morning: 12 Rusty-dot Pearl, 9 Silver Y, a Diamond-back Moth, a Rush Veneer, a Delicate and a Clancy's Rustic.

Late news for Saturday (27th): the island's first Yellow-browed Warbler of the autumn was heard calling at Reap Lane early in the morning.

 

      

  

  

  

   Yellow-browed Warbler, Nightjar and Continental Coal Tit - Portland Bill, 28th September 2008 © Martin Cade

...the Nightjar was interesting as it was a good deal smaller than we'd expected (wing length 175mm and tail length 112mm, as opposed to ranges given in BWP for British Nightjars of 183-202mm for the wing and 123-146mm for the tail). We know pretty well nothing about Nightjars but the literature seems to indicate that, at least in the Western Palearctic, birds from the south and east of the species range are smaller and paler/plainer/greyer than British birds; our individual might just be a runt youngster but it'll be interesting to see how the plumage of this bird compares with those from the southern/eastern populations. Another bird that has been putting on a good show has been the Continental Coal Tits in the Obs garden. The blue back, out-sized bib and little tufty crest certainly give birds of this form a characterful appearance but we get the feeling that they're very under-appreciated by the majority of birders. We've followed this bird around for a while over the weekend trying to get a few sound recordings as there seems to be something about the vocalisations of ater that doesn't tally with the usual vocabulary of British Coal Tit (but there again, being marooned on the end of Portland we aren't exactly well up on the full vocal repertoire of British Coal Tit); click here to listen to a sequence of both calling and singing this morning, and here for a composite of a whole host of calls recorded at various times yesterday.

  28th September

Despite almost cloudless skies there were a lot more birds grounded today (presumably the influence of the New Moon period?) of which the most noteworthy were a Nightjar trapped and ringed at the Obs and a Yellow-browed Warbler in the Obs garden; the Continental Coal Tit was also still there for a while early in the morning before it moved on to Culverwell. Chiffchaffs and Goldcrests were the most conspicuous commoner migrants, with both topping the 100 mark at the Bill, whilst Stonechats are also starting to figure in some numbers, with at least 25 at the Bill today. A day-list of some variety also included singles of Merlin, Short-eared Owl, Great Spotted Woodpecker, Grasshopper Warbler and Firecrest amongst small numbers of most of the usual late September migrants at the Bill; quality elsewhere included another Firecrest at Reap Lane and a Little Stint at Ferrybridge.

...the in-hand bird showed some characters suggestive of eastern origin (notably the pale brown mantle and tertial edges, the pale crown and strongish supercilium) but the tail pattern wasn't especially different to a British bird so we won't be wasting much time trying to assign this individual to any of the named subspecies.

  27th September

Fairly uneventful in really glorious summer-like conditions today. The Continental Coal Tit remained at the Obs but lots of weekend coverage otherwise revealed just a light scatter of Wheatears, Blackcaps, Chiffchaffs and Goldcrests everywhere and surprisingly little on the move overhead. The only faintly interesting less regular migrants reported were a Little Stint at Ferrybridge, a Merlin and a Mistle Thrush at Tradecroft and 2 Snipe, 2 Short-eared Owls, 2 Lesser Whitethroats (one of which showed some features of one or other of the eastern forms), a Turtle Dove and a Redstart at the Bill.

Still nothing of particular note in the Obs garden moth-traps this morning, with 7 Rusty-dot Pearl, 2 Delicate and 2 Silver Y the only immigrants recorded.

Late news for yesterday: the first Ring Ouzel of the autumn was at Priory Corner.

  26th September

There were welcome morsels of quality today in the form of a Lapland Bunting over Top Fields early in the morning, yet another Honey Buzzard that flew south down the island later in the morning and a Continental Coal Tit that was trapped and ringed at the Obs early in the afternoon. Under very clear skies and freshening north-easterly there was plenty of movement, particularly of Meadow Pipits, very high overhead but once again nothing in any great quantity on the ground, with the best of the bunch at the Bill being 40 Chiffchaffs, 20 Wheatears, 15 Yellow Wagtails, 15 Goldcrests, 10 Whinchats, 10 Blackcaps, 9 Siskins, 7 Tree Pipits, 4 Grey Herons, 3 Snipe, 3 Grey Wagtails, 2 Redstarts, 2 Garden Warblers, 2 Spotted Flycatchers and a Lesser Whitethroat.

It was another pretty hopeless night for immigrant moths with nothing more than 22 Rusty-dot Pearl and 5 Silver Y caught in the Obs garden traps.

25th September

Welcome to the website of one of the few British bird observatories whose recording area isn't awash with Siberian vagrants. Portland's only oddities today were another 2 Honey Buzzards: one flew south along the West Cliffs before heading away to the east over the Bill late in the morning and the second appeared over the north of the island before heading away east towards the Purbecks late in the afternoon; otherwise it was more or less a repeat of recent days with small numbers of grounded common migrants and a light passage of overflying hirundines, wagtails, pipits and finches. Most of the coverage was of the Bill area where 20 Yellow Wagtails, 10 Siskins, 8 Tree Pipits, 6 Golden Plovers, 5 Grey Wagtails, 3 Short-eared Owls, 3 Pied Flycatchers, 2 Turtle Doves, 2 Garden Warblers, 2 Spotted Flycatchers and singles of Lapwing, Snipe, Redstart and Lesser Whitethroat were the pick of a very routine selection.

Nineteen Rusty-dot Pearl and a Silver Y were the only immigrants in the Obs garden moth-traps this morning.

24th September

Still no sign of any of the goodies that a fortnight of easterly weather ought to have produced. Another two Honey Buzzards left to the south at the Bill during the morning but otherwise it was a day of routine migrants in relatively small numbers. The first 2 Redwings of the autumn dropped in at the Bill, where there were also 40 Chiffchaffs, 25 Yellow Wagtails, 20 Wheatears, 10 Goldcrests, 3 Short-eared Owls, 3 Whinchats, 3 Blackcaps, 3 Spotted Flycatchers, 2 White Wagtails, a Merlin, a Lesser Whitethroat and a Garden Warbler. Heavy cloud cover put paid to much in the way of visible passage although 13 Siskins, 3 Grey Wagtails, 2 Snipe and a Ringed Plover passed over the Bill amongst a little movement of the usual Meadow Pipits and hirundines. The only report from elsewhere was of a Little Stint at Ferrybridge.

The only immigrants/wanderers attracted to the Obs garden moth-traps overnight were 6 Rusty-dot Pearl, a Frosted Orange and a Silver Y.

  23rd September

With just one exception - a Honey Buzzard that arrived in off the sea at the Bill during the evening - it was a day of pretty standard fare, with a little more on the ground than in recent days and still quite a bit to see/hear overhead. Grounded Meadow Pipits have been increasing in recent days and today between 500 and 1000 were scattered widely in the Bill area, where there were also 50 Wheatears, 40 Chiffchaffs and 10 Goldcrests; 3 Short-eared Owls and a single Turtle Dove were the pick of the fair selection of other species in single figure totals there. Overflying hirundines were well into a four figure total at the Bill, where 2 Hobbys and a Merlin passed through but most of the other expected wagtails, pipits and finches were somewhat fewer in number than might have been hoped on a clear, breezy morning.

In rather brisk conditions overnight the only immigrants attracted to the Obs garden moth-traps were 7 Rusty-dot Pearl, 6 Silver Y and 2 Dark Sword Grass.

 

   

  

   Autumn equinox sunrise and Melodious Warbler - Portland Bill and Culverwell, 22nd September 2008 © Martin Cade 

  22nd September

The Culverwell Melodious Warbler - which was trapped and ringed today - was still present but otherwise it was fairly quiet: another mainly clear night meant that precious little was grounded, whilst some heavy cloud that lingered overhead from dawn until well into the morning seemed to restrict visible passage to small numbers of the usual hirundines, wagtails, pipits and finches. What little there was on the ground included a thin sprinkle of the commoner September migrants everywhere along with minor oddities such as 2 Lapwings and singles of Redshank, Snipe, White Wagtail and Grasshopper Warbler at the Bill. Four Balearic Shearwaters passed through off the Bill. The only reports from elsewhere were of 5 Mediterranean Gulls and 5 Sandwich Terns in Portland Harbour.

This morning's immigrant list in the Obs garden moth-traps consisted of 12 Silver Y, 12 Rusty-dot Pearl and singles of Diamond-back Moth, Convolvulus Hawk-moth and Delicate.

Late news for yesterday: a Wryneck was evidently seen during the afternoon near Culverwell by two visiting bird club parties who didn't report the sighting at the time.

21st September

With virtually no change in the weather it was a case of same birds, slightly different numbers. The Culverwell Melodious Warbler was present for yet another day and the raptor tally reached a relatively lowly 2 Honey Buzzards (one south all along the West Cliffs mid-morning and another south over the Bill early afternoon) and 1 Hobby. Hirundines again streamed through and 55 Siskins were amongst the wealth of other over-flying migrants at the Bill. It was again rather quiet on the ground where 16 Whinchats, 5 Grasshopper Warblers, a Short-eared Owl and a Firecrest were among the better sightings at the Bill and a Little Stint was still present at Ferrybridge. The sea was again largely neglected although odd watches at the Bill did produce 3 Balearic Shearwaters, a Great Northern Diver and a Sooty Shearwater.

The immigrant tally continued to drop in the Obs garden moth-traps which produced just 6 Silver Y, 2 Rusty-dot Pearl and 2 Dark Sword Grass.

  20th September

The Culverwell Melodious Warbler remained in situ but most of the other interest revolved around the continuing overhead raptor-fest, with a total of 6 Honey Buzzards, 3 Hobbys and an Osprey heading south during the day; 3 of the Honey Buzzards passed over the Bill during the first hour of daylight whilst all the other raptors were all spotted from the Portland Heights area between late morning and early evening. Routine passage was much as in recent days: hirundines, wagtails, pipits and Siskins were conspicuous overhead but grounded migrants were not at all plentiful; the pick of the scarcer migrants were 3 Grasshopper Warblers, a Merlin and a Great Spotted Woodpecker at the Bill and a Little Stint at Ferrybridge. Precious little attention was paid to the sea although a lone Balearic Shearwater was noticed passing the Bill.

Immigrants in the Obs garden moth-traps this morning included 39 Silver Y, 10 Rusty-dot Pearl, 5 Rush Veneer and a Dark Sword Grass.

Late news for yesterday: 3 Short-eared Owls were at the Bill in the evening and a Honey Buzzard flew on to the north of the island just prior to dusk.

  19th September

Our Indian summer continued and once again migrants overhead were far more conspicuous than those on the ground. The Culverwell Melodious Warbler remained as did the Barleycrates Lane Wryneck, whilst a new Wryneck turned up at Watery Lane; raptor interest was provided a Honey Buzzard around the north-east of the island during the morning and another probable Honey Buzzard that headed south off the same area without ever coming ashore a little later. Hirundines (numbering in the order of 5-10000) dominated overhead where many lingered instead of passing straight through; Meadow Pipits were also well into a four figure total and there were fair numbers of all the other expected pipits, wagtails and finches. Grounded migrants included a few more Chiffchaffs than in recent days but otherwise just 2 Great Spotted Woodpeckers at the Bill by way of minor quality. The first couple of Brent Geese of the autumn passed through off the Bill.

Overnight immigrant interest in the Obs garden moth-traps was restricted to 25 Silver Y, 12 Rusty-dot Pearl, 2 Diamond-back Moth, 2 Dark Sword Grass and a Pearly Underwing; a single Frosted Orange was also an unusual capture at the Bill.

  18th September

Another day when, hirundines aside, quality outweighed quantity. The quality was provided by the Melodious Warbler that lingered on at Culverwell, a Wryneck that showed up at Barelycrates Lane, a Honey Buzzard that left to the south from the Bill during the morning and two single Ospreys that passed over the north of the island (mid-morning and early afternoon respectively). After a crystal clear night there was no expectation of any fall of migrants and all that could be mustered was a wide scatter of small numbers of most of the expected mid-autumn species. It was much busier overhead where hirundines (House Martins easily outnumbering Swallows) were moving in the low thousands per hour for most of the morning

The overnight immigrant tally in Obs garden moth-traps included 25 Silver Y,  9 Rusty-dot Pearl, 4 Dark Sword Grass and singles of Diamond-back Moth, Rush Veneer, Pearly Underwing, White-speck, Delicate and Scarce Bordered Straw.

  17th September

Very little to show for today's fieldwork. The Melodious Warbler remained at Culverwell and a Marsh Harrier was at the Bill for an hour or so after dawn but there was little except Swallows on the move overhead and the quest for any numbers of grounded migrants went largely unrewarded. The best of a thin selection at the Bill were 3 Sedge Warblers, 2 Grey Wagtails, 2 Whinchats, 2 Redstarts, 2 Siskins and singles of Hobby, Swift, Grasshopper Warbler, Garden Warbler, Blackcap, Spotted Flycatcher and Pied Flycatcher, whilst singles of Hobby at Cheyne Weare and Grey Plover and Little Gull at Ferrybridge were the only reports of note from elsewhere.

It was again too chilly and breezy for productive overnight mothing, although the Obs garden traps still attracted a small selection of immigrants: 40 Silver Y, 5 Diamond-back Moth, 3 Rusty-dot Pearl, 3 Dark Sword Grass, 2 Rush Veneer and singles of Pearly Underwing and White-speck.

Late news for yesterday: a Wryneck dropped in briefly on the West Cliffs at the Bill...and belated news for 11th September: a Tawny Pipit showed well on and around the fence on the north side of Southwell Business Park (the observer reported that it looked to be very similar to the bird photographed not too far away at Barelycrates Lane a few days previously so perhaps the same individual was involved?)

  16th September

Another nice list of scarcer migrants today included the Melodious Warbler that remained at Culverwell, a Corncrake flushed up once in Top Fields, a Marsh Harrier overhead at the Bill early in the morning and an Osprey that flew south along the West Cliffs from Fortuneswell to the Bill later in the morning; unfortunately, commoner migrants - Swallows aside - were still not at all plentiful. The light scatter of routine migrants at the Bill included 25 Yellow Wagtails, 20 Siskins, 10 Grey Wagtails, 6 Tree Pipits, 4 Whinchats, 2 Short-eared Owls, a Hobby, a Merlin, a Redstart and a Lesser Whitethroat; other sites produced more, or in most cases less, of the same.

In chillier conditions overnight there weren't quite so many immigrant moths on the wing at the Bill; the Obs garden traps produced 26 Silver Y, 11 Diamond-back Moth, 8 Rusty-dot Pearl, 6 Rush Veneer and singles of Vestal, Gem, Delicate, Porter's Rustic and Scarce Bordered Straw.

 

   

  

  

  

  

  

  

   Marsh Harrier, Antigastra catalaunalis and some Pied Flycatcher detail - Ferrybridge and Portland Bill, 15th September 2008 © Pete Saunders (Marsh Harrier) and Martin Cade (A. catalaunalis and the flycatchers).

...having seen today's debate concerning flycatchers in other parts of the country we thought we'd cobble together a few photographs showing some first-winter Pied Flycatchers from the last few days. Saturday's bird shown in the top two photos was particularly interesting as it was distinctly colder, greyer toned than usual and had a really large white primary patch (which started on P5 as opposed to the usual P6); we had a good look at this bird but unfortunately the wing formula/biometry (for example, P2=P5/6 and P1-P2=37) were good for Pied Fly and the nape feathers just had concealed white central shaft streaks as opposed to the white anchor marks that we'd hoped to see had it have been a Collared! Although the primary patch on this bird is large it actually doesn't extend much - if at all - beyond the longest primary covert. We'd guess that this individual was a female as it had no black on the upper tail coverts; our other two birds from this past weekend are likely to be males as they had black upper tail coverts and much darker flight feathers, wing coverts and tails. The bird in the centre photograph has a somewhat smaller primary patch (with just a faint spot on P6) and the individual in the lower two photos has such a small patch that it isn't visible at all on the closed wing.

  15th September

Portland hardly vies with Falsterbo in the raptor stakes but a Honey Buzzard heading south over the north of the island during the morning and 3 Marsh Harriers leaving in the same direction (one off the West Cliffs early in the morning and the other two over Ferrybridge either side of midday) were very welcome; on the land the Melodious Warbler remained at Culverwell for its sixth day. A veil of cloud overhead at dawn did little to perk up interest on the land but under clearer skies later in the day Swallows were again moving in quantity, with sample counts suggesting totals of around 3500/hour flying south at Ferrybridge around midday; 50 Siskins, 2 Short-eared Owls, a Merlin and a Turtle Dove were the best of a pretty thin selection of routine migrants at the Bill, where a lone Balearic Shearwater was the only bird of note on the sea.

Immigrants were again quite well represented in the Obs garden moth-traps. A single Antigastra catalaunalis was the rarity highlight although at a local level the second island record of Tachystola acroxantha was perhaps more notweworthy; other totals included 130 Silver Y, 30 Rusty-dot Pearl, 20 Rush Veneer, 9 Diamond-back Moth, 7 Dark Sword Grass, 2 Vestal, a Convolvulus Hawk-moth, a Pearly Underwing and a White-speck.

14th September

Thank goodness for the long-staying Melodious Warbler since, for all the talk of imminent Honey Buzzards and eastern rarities, there wasn't a great deal of note to be seen around the island today. In more very fair conditions most routine passage took place high overhead with, for example, plenty more wagtails, pipits and Siskins on the move amongst the myriad hirundines leaving to the south. It was much quieter on the ground with the Bill area producing just 3 Pied Flycatchers, 2 Reed Warblers and singles of Hobby, Snipe, Redstart and Lesser Whitethroat by way of minor interest. The seawatchers were eventually rewarded with a tally that included 6 Great Skuas, 4 Balearic Shearwaters, 2 Wigeon, an Arctic Skua and a Pomarine Skua passing through off the Bill, whilst elsewhere a Grey Phalarope was briefly settled in Portland Harbour before flying off towards Chesil Cove.

The recent improvement in immigrant numbers in the Obs garden moth-traps continued, with totals this morning that included 50 Silver Y, 9 Rusty-dot Pearl, 8 Rush Veneer, 3 Delicate, 2 Porter's Rustic, a Dark Sword Grass and a Cosmopolitan.

 

   

   Dewick's Plusia - Portland Bill, 13th September 2008 © Martin Cade

  13th September

The Melodious Warbler remained at Culverwell where there were several sightings of 2 Hippolais warblers but seemingly not a fully confirmed sighting of an Icterine Warbler. With quality otherwise at a premium it was left to a rather similar variety of commoner migrants to yesterday to provide the interest. Under cloudless skies most movement was overhead, with four figure totals of both Swallow and House Martin, along with 40 Siskins, 24 Tree Pipits,10 Grey Wagtails and 2 Swifts the pick of the list at the Bill. The light scatter of grounded migrants included 20 Yellow Wagtails, 6 Pied Flycatchers, 3 Redstarts, 2 Sedge Warblers, a White Wagtail, a Whinchat and a Reed Warbler at the Bill.

A Dewick's Plusia was the pick of the overnight catch in the Obs garden moth-traps; commoner immigrants included 37 Silver Y, 7 Rush Veneer, 7 Rusty-dot Pearl, 2 Dark Sword Grass and a Pearly Underwing.

 

   

  

  

  

   Icterine Warbler, Melodious Warbler and Grey Wagtail detail - Portland Bill, 12th September 2008 © Martin Cade

...catching an adult Grey Wagtail at Portland is about as rare as getting Melodious and Icterine Warblers together here, so rather than waiting on the faint chance of a comparison photo we'll just dwell for a moment on the first year Grey Wag netted this morning. Ageing isn't usually too difficult as there ought to be a relatively obvious moult-limit in the greater coverts (although usually only the innermost one-three feathers are replaced by adult pattern feathers); there is often also a moult-limit within the tertials and for those odd few birds that haven't replaced any greater coverts there is always a contrast to be looked for between these dull brownish tinged feathers and the glossier black median coverts which seem always to be replaced in the post-juvenile moult.

  12th September

A rare Portland event today: an Icterine Warbler was a new arrival at Culverwell where it joined the Melodious Warbler already present; the Reap Lane Woodchat Shrike was also still present and a Wryneck was another new arrival at Kingbarrow Quarry.. After a very clear night grounded commoner migrants weren't at all numerous but did include, for example, 10 Whinchats at Barelycrates Lane and 20 Whinchats, 4 Sedge Warblers, 3 Grasshopper Warblers, a Turtle Dove, a Short-eared Owl, a Reed Warbler, a Garden Warbler and a Pied Flycatcher at the Bill. Quite a bit on the move overhead included 45 Siskins, 17 Grey Wagtails, 14 Tree Pipits, 5 Chaffinches, 2 Swifts, a Merlin, a Golden Plover, a Snipe and a Crossbill at the Bill. The first Red-throated Diver of the autumn was the only bird of note on the sea at the Bill.

A small improvement in immigrant numbers in the Obs garden moth-traps this morning included 17 Silver Y, 4 Rush Veneer, 4 Rusty-dot Pearl, 4 Delicate, 2 Dark Sword Grass, 2 Pearly Underwing and a Porter's Rustic.

11th September

Dire on the migrant front today (for example, nothing at all was netted and ringed all day at the Obs!) so it was fortunate that both of yesterday's goodies - the Melodious Warbler at Culverwell and the Woodchat Shrike at Reap Lane - remained overnight. What few grounded migrants there were were mainly left-overs and included 10 Wheatears, 5 Grey Wagtails, 2 Chiffchaffs, 2 Willow Warblers, a Turnstone, a Snipe, a Garden Warbler and a Pied Flycatcher at the Bill; elsewhere a Little Stint was a new arrival at Ferrybridge. Conditions didn't look too bad for another decent seawatch session but in the event just 6 Arctic Skuas, 4 Great Skuas, 3 Sooty Shearwaters, 3 Common Scoter, a Balearic Shearwater, a Whimbrel and a Pomarine Skua passed through off the Bill.

A lone Convolvulus Hawk-moth was a welcome better quality immigrant in the Obs garden moth-traps this morning; 2 Silver Y and a Dark Spectacle were the only other worthwhile captures.

Late news for yesterday: a few more late afternoon/evening seabirds boosted the day-totals at the Bill to 27 Arctic Skuas, 19 Sooty Shearwaters, 15 Great Skuas and 13 Balearic Shearwaters.

 

   

  

  

   Melodious Warbler and Woodchat Shrike - Culverwell and Reap Lane, 10th September 2008 © Martin Cade

  10th September

On the land it was very much a case of quality rather than quantity: singles of Melodious Warbler at Culverwell and Woodchat Shrike at Reap Lane showed on and off from late morning through the afternoon but an early morning Tawny Pipit on the West Cliffs near Weston was not so co-operative and was not seen after discovery. Commoner migrants were not at all plentiful but did include 4 Garden Warblers, 4 Blackcaps, 2 Reed Warblers, a Whinchat and a Pied Flycatcher at the Bill. The sea continued to provide quite a bit of interest, with 17 Sooty Shearwaters, 12 Arctic Skuas, 8 Common Scoter, 6 Manx Shearwaters, 3 Balearic Shearwaters and 2 Sandwich Terns passing through off the Bill.

Another disappointing catch of immigrant moths at the Obs included 5 Silver Y, 2 Dark Sword Grass, 2 Delicate, a Rusty-dot Pearl, a Rush Veneer and a Pearly Underwing.

 

   

   Reed Warbler - Portland Bill, 9th September 2008 © Martin Cade

  9th September

In really miserable conditions the smattering of new arrivals on the land included 2 Reed Warblers and singles of Grey Heron, Knot, Turtle Dove, Pied Flycatcher and Spotted Flycatcher at the Bill where surprising high numbers of Swallows left out to sea in the rain. Seawatching at the Bill produced 37 Common Scoter, 18 commic terns, 17 Great Skuas, 16 Arctic Skuas, 10 Manx Shearwaters, 3 Sandwich Terns, a Grey Phalarope and an Arctic Tern. News from elsewhere included an early morning Ortolan Bunting at Barelycrates Lane and 63 Sandwich Terns, 3 Sanderling and an Arctic Tern at Ferrybridge.

In what looked to be quite promising overnight conditions the only immigrants attracted to the Obs garden moth-traps were 5 Silver Y and singles of Rusty-dot Pearl, Rush Veneer, Dark Sword Grass and Red Admiral butterfly.

Late news for yesterday: further details received regarding the plumage of the Watery Lane Ortolan Bunting indicate that it was a different individual to the bird photographed at the Bill.

  8th September

In much calmer conditions there was quite a bit on the move overhead but a rather disappointing array of new arrivals on the ground; single Ortolan Buntings - the same bird in each case? - that showed up during the afternoon first at Watery Lane and later at the Obs were the only oddities discovered. At the Bill the overhead tally included 29 Tree Pipits, 25 Yellow Wagtails and 23 Grey Wagtails along with a relatively small passage of hirundines and the first movement of the autumn of a few hundred Meadow Pipits. On the ground there were small numbers of Wheatears everywhere (including 30 at the Bill) but most other common migrants, which included the first couple of Goldcrests of the autumn at Southwell, were only present on ones and twos; the pick of the scarcer species included 3 White Wagtails, 3 Spotted Flycatchers, 2 Grasshopper Warblers, 2 Garden Warblers, a Snipe, a Lesser Whitethroat and a Reed Bunting at the Bill and a Pied Flycatcher at Reap Lane. The only reports of note from the sea were of 2 Manx Shearwaters and 2 Arctic Skuas passing the Bill.

The overnight immigrant tally in the Obs garden moth-traps consisted of 13 Silver Y, 3 Dark Sword Grass and 1 Delicate.

 

   

  

  

  

  

  

  Grey Phalaropes and some more Whitethroat detail - Chesil Cove and Portland Bill, 7th September 2008 © Kevin Lane (Grey Phalaropes) and Martin Cade (Whitethroats).

...a couple of weeks ago we touched on Whitethroat ageing and remarked on how tricky they can be - a point well illustrated by two of today's birds. The top three photos are of an adult (being a rather brown headed bird we'd hazard a guess that it was more likely to be a female). Like the presumed males we illustrated before this individual shows evidence of a moult interruption with, for example, the central two secondaries, the carpal covert and the smallest alula feather all left unmoulted; the photo of the closed wing shows how with careful observation it might just be possible to spot the old secondaries in the field. The two photos of a first year bird show one of those troublesome individuals that has very white outer tail-feathers (in a fleeting field view this would surely be called as an adult!). In this case correct ageing requires closer inspection of the rest of the tail (for example, the paler overall colour of the tail, the thinner, more pointed shape of the individual feathers and the pattern of white on the penultimate feather) and a look at the greater coverts (this individual is particularly subtle, with just the innermost feather - which very unhelpfully is nearly always hidden on a field view - having been moulted and showing the adult-like pattern of a dark centre and well-defined rufous edge).

Up to 4 Grey Phalaropes remained off Chesil Cove but otherwise there was relatively poor reward for the weekend visitors. In slightly improved weather conditions - well, at least it was dry all day - there was a noticeable improvement in common migrant numbers, with 120 Wheatears grounded at the Bill and 12 Grey Wagtails, 12 Tree Pipits and good numbers of hirundines passing overhead there; most other expected species were only poorly represented but odds and ends of better quality included 11 White Wagtails, 9 Turnstones, 7 Whinchats, 2 Spotted Flycatchers, a Garden Warbler and a Pied Flycatcher at the Bill, 2 Whinchats and a Sedge Warbler at Barleycrates Lane and 16 Sanderling and a Bar-tailed Godwit at Ferrybridge. With the wind having veered into the north-west sea interest was restricted to 5 Manx Shearwaters, 3 Arctic Skuas and a Balearic Shearwater passing through off the Bill.

Two Bottle-nosed Dolphins were off the Bill this morning.

...with so many other photographs to post in the last couple of days we hadn't got round to this colour-ringed Lesser Black-back that was at the Bill the day before yesterday. Peter Rock informs us that this bird was ringed at Cardiff on 7th July 2004 and that there had been further sightings of it near Bilbao, Spain, in July 2006, at A Coruña, also in Spain, in February 2007 and near Les Sables d'Olonne, France, in October 2007.

  6th September

Another Long-tailed Skua - this one lingering for a good part of the afternoon off Chesil Beach - provided today's highlight. Once again virtually all the other news was of seawatching, with 8 Arctic Skuas, 3 Grey Phalaropes, a Pomarine Skua and a Little Gull passing through/lingering off Chesil Cove and 7 Balearic Shearwaters, 4 Manx Shearwaters, 3 Arctic Skuas, a Storm Petrel and a Great Skua the pick of another relatively poor selection at the Bill. The few sightings from the land included 2 Knot at Ferrybridge and 4 White Wagtails, a Knot and a Pied Flycatcher at the Bill.

In slightly less windy conditions overnight singles of Diamond-back Moth, Rusty-dot Pearl and Scarce Bordered Straw provided a little immigrant interest in the Obs garden moth-traps.

  5th September

In a howlingly strong southerly the Tawny Pipit remained at Barleycrates Lane but pretty well all the other news was from the seawatchers. The bird of the day was a Long-tailed Skua that passed overhead at Ferrybridge; 68 Sandwich Terns and 13 commic terns also passed through there and 6 Sanderling and a Bar-tailed Godwit were amongst the waders present. At the Bill the quality per hour quotient was on the low side with all-day totals that comprised 93 commic terns, 30 Common Terns, 16 Arctic Skuas, 15 Common Scoter, 7 Manx Shearwaters, 5 Guillemots, 4 Great Skuas, 3 Balearic Shearwaters, 3 Sooty Shearwaters and 2 Arctic Terns. The only additional report from the land was of a Pied Flycatcher in the Obs garden.

...quite an influx of new gulls today included 3 Yellow-legged Gulls (the bird above is moulting from second-summer into third-winter plumage - one of the less regular plumages seen at the Bill) and half-a-dozen intermedius Lesser Black-backs (the first multiple arrival so far this autumn).

  4th September

The Tawny Pipit remained at Barleycrates Lane and 2 Grey Phalaropes were new arrivals at Chesil Cove. On the land there were just ones and twos of a few routine common migrants, with the only minor oddities reported being 3 Yellow-legged Gulls and a lone Turtle Dove at the Bill. Despite getting plenty of attention in the continuing windy conditions the sea didn't come up with a great deal more than the phalaropes, with watches at the Bill producing just 8 Common Scoter, 5 Manx Shearwaters, 2 Balearic Shearwaters, 2 Sandwich Terns and singles of Sooty Shearwater, Great Skua and  Arctic Skua.

...most of the wagtails are no trouble at all but there are always some that make you think twice.

  3rd September

The Tawny Pipit remained at Barleycrates Lane but there was no sign of the Rose-coloured Starling or any Ortolan Buntings at the Bill. In an incessant strong wind birding on the land was never easy but it was apparent that there were precious few new arrivals anywhere; the best of what did crop up were 5 White Wagtails and 2 Pied Flycatchers at the Bill and a Crossbill over Barelycrates Lane. The sea received quite a bit of attention but nothing much more than 7 Manx and 6 Balearic Shearwaters passed through off the Bill.

...we've always thought rump colour was a pretty dodgy identification feature (quite apart from the fact that it's usually extremely hard to judge accurately in the field) in the Pied vs White Wagtail debate and our flight shot does little to dispel that feeling.

  2nd September

The Rose-coloured Starling at the Bill and the Tawny Pipit (click here to listen to short recording of the slightly sparrow-like flight call of this bird; you'll probably have to turn the sound right up on your computer as the bird was only calling rather quietly and it was hellish windy at the time! - we'll try and have another go at a recording if the wind ever dies down here) at Barleycrates Lane were both still present and entertained a steady stream of visitors all day; an Ortolan Bunting was also reported to still be present in Top Fields but was much more elusive in the windy conditions and escaped the attention of most observers. On the common migrant front there were practically no new arrivals after a night of constant wind and rain, and it was left to lingerers such as 6 White Wagtails at the Bill and a Pied Flycatcher at the Bill to provide what interest there was; a roosting Barn Owl was also discovered in Top Fields. Despite promising-looking conditions there was precious little on the move at sea, with just 30 Common Scoter, 4 Manx Shearwaters, 4 commic terns, 2 Sandwich Terns and singles of Balearic Shearwater, Great Skua and Arctic Skua logged at the Bill. The only other reports were of 5 Sanderling, 3 Mediterranean Gulls and a Little Gull at Ferrybridge.

Late news for yesterday: we forgot to update the seawatch figures for the day which included final totals of 66 Balearic Shearwaters and 21 Manx Shearwaters passing the Bill; 5 Great Skuas, 3 Arctic Skuas and a probable Long-tailed Skua also passed through off Chesil Cove.

  1st September

The Rose-coloured Starling showed well as it wandered between the Coastguard Cottages and the Bill Lighthouse through the day but the other scarcities proved to be much more elusive: there were just single sightings of one of the Ortolan Buntings and the Wryneck at the Bill early in the morning, a Tawny Pipit that was reported first as a probable fly-over at Top Fields popped up briefly a couple of times at Barleycrates Lane before finally being pinned down there in the evening, another Ortolan Bunting also showed a couple of times at Barleycrates Lane and another Wryneck visited a private garden at Southwell. Yellow Wagtails and Wheatears were still quite numerous at the Bill, where there were also 11 White Wagtails, but most other common migrants were in very reduced numbers; the best of the less regular species were singles of Hobby, Merlin, Grasshopper Warbler and Lesser Whitethroat at the Bill and Grasshopper Warbler and Pied Flycatcher at Southwell. In increasingly blustery conditions the sea produced 60 Balearic Shearwaters, 3 Arctic Skuas, 2 Manx Shearwaters and a Sooty Shearwater passing through off the Bill.

The strength of the wind spoilt overnight mothing and the only immigrants caught in the Obs garden traps were 10 Silver Y and 2 Rusty-dot Pearl.
