Another pleasantly calm day allowed plenty of opportunity to look for late migrants and scour Portland Harbour for waterbirds. The harbour came up with the day's highlight in the form of a Black Guillemot that showed up - albeit very distantly - during the afternoon; more mundane fare about the harbour included 14 Black-necked Grebes, 17 Guillemots, 10 Great Northern Divers, 10 Razorbills and singles of Red-necked Grebe and Eider. Late migrants weren't as plentiful as yesterday at the Bill, but still included fair numbers of Blackbirds, Song Thrushes, Redwings and Chaffinches, together with 5 Snipe, 5 Fieldfares, 2 Bramblings, 2 Reed Buntings and singles of Grey Heron, Short-eared Owl, Blackcap, Chiffchaff, Goldcrest and Redpoll; 6 Red-throated Divers passed through on the sea there.

  29th November

A thoroughly enjoyable day to be out birding: unbroken sunshine, hardly a breath of wind and - particularly for so late in the season - a really nice flurry of newly arrived migrants. The newcomers included nothing at all out of the ordinary and precious little that lingered for long under such clear skies, but totals for the Bill area included 100 each of Blackbird and Chaffinch, 45 Redwings, 30 Song Thrushes and single figure counts of Lapwing, Golden Plover, Fieldfare, Blackcap, Brambling, Siskin, Redpoll and Reed Bunting. Seawatching at the Bill came up with 7 Red-throated Divers and 4 Brent Geese, whilst 12 Black-necked Grebes and singles of Great Northern Diver, Red-necked Grebe, Slavonian Grebe and Long-tailed Duck were still in Portland Harbour.

Another constant, albeit light, trickle of new arrivals today included the second Waxwing of the week that dropped in for a short while at Ladymead/Reforne. At the Bill the day's tally included 15 Redwings, 8 Fieldfares, 3 Water Rails, 2 Bramblings and singles of Woodcock, Snipe, Short-eared Owl and Black Redstart, whilst elsewhere there was a Merlin near the Windmills. A settled flock of up to 12 Common Scoter lingered off the Bill, where 5 Red-throated Divers, 2 Brent Geese and a Velvet Scoter also passed by; at least 4 Black-necked Grebes, 2 Great Northern Divers, 2 Slavonian Grebes and a Red-necked Grebe were still in Portland Harbour.

27th November

A day without rainfall was a bit of a welcome novelty, whilst there was the added bonus of the chillier conditions that look to be setting in producing a fair little arrival of late migrants. The Bill area got most of the coverage and returned totals of 100 Chaffinches, 40 each of Blackbird and Song Thrush, 14 Redwings, 3 each of Fieldfare and Brambling, 2 each of Brent Goose, Snipe and Blackcap, and singles of Grey Heron, Golden Plover, Lapwing and Black Redstart; elsewhere, 2 Firecrests were at Pennsylvania Castle. Three Red-throated Divers and a Great Northern Diver passed through off the Bill, whilst Portland Harbour came up with 6 Black-necked Grebes, 4 Great Northern Divers and singles of Red-throated Diver, Red-necked Grebe and Eider.

  26th November

Not altogether unexpectedly - although rather earlier in the winter than we'd imagined - a Waxwing that spent a few minutes in the tree-tops in the Obs garden during the afternoon was the day's star bird. The gradually improving conditions saw a few other new arrivals show up, with 50 Chaffinches, 6 Redwings, 4 Water Rails (at least one of which was new in), 3 Fieldfares, 3 Bramblings, a Merlin, a Woodcock and a Snipe on the ground in the Bill area, and still a little finch passage (including 120 Linnets south) going on overhead there. The day's only reports from the sea were of singles of Red-throated Diver and Pomarine Skua through off the Bill.

25th November

After a fair-ish start the weather quickly deteriorated into a succession of increasingly heavy showers. Given the conditions, there were a surprising variety of reports from the weekend visitors: a Long-tailed Duck was a notable new arrival in Portland Harbour, where more routine fare included 6 Great Northern Divers, 4 Black-necked Grebes and singles of Red-necked Grebe and Slavonian Grebe, 8 Pintail, 3 Red-throated Divers and singles of Great Northern Diver and Golden Plover passed through off the Bill and 2 Firecrests and a Great Spotted Woodpecker were at Pennsylvania Castle.

Singles of Rush Veneer and Silver Y made up the immigrant tally in the Obs garden moth-traps.

24th November

Another day of weather excesses saw it raining from dawn 'till dusk. One hardy seawatcher was rewarded with 2 Gadwall and singles of Red-throated Diver, Red-breasted Merganser and Little Auk passing through off the Bill, whilst singles of Redwing and Fieldfare at the Bill were the only sightings of note on the land.

  23rd November

After a night of weather excesses it was quite a surprise to wake to much more benign conditions at dawn. The improvement probably came too late to allow many migrants to get moving, with the only obvious new arrivals at the Bill being 130 southbound Goldfinches and smaller numbers of other routine finches (as well as a likely Serin heard calling) overhead and 2 Redwings, 2 Robins and singles of Fieldfare and Blackcap on the ground; 3 Water Rails, 3 Chiffchaffs, 2 Black Redstarts and a Purple Sandpiper also there was presumed winterers. Seawatching at the Bill produced 10 Common Scoter, 3 Red-throated Divers, 2 Great Norhern Divers and a Red-necked Grebe, whilst the calm conditions allowed for good coverage of Portland Harbour, that revealed 11 Black-necked Grebes, 6 Great Northern Divers, a Red-necked Grebe and an Eider.

22nd November

In increasingly stormy conditions nearly all the day's reports came from the sea: 3 Common Scoter, 2 Great Skuas, a Great Northern Diver and a Manx Shearwater through off the Bill and 4 Common Scoter and a Red-throated Diver through off Chesil Cove. The only report from the land was of a Black Redstart at the Bill.

Immigrants in the Obs garden moth-traps: 2 Diamond-back Moth, 2 Silver Y and 1 Dark Sword Grass.

21st November

Another day with precious few incentives to spend long in the field. The only reports came from the Bill, where 7 Black-headed Gulls, 5 Common Scoter and singles of Manx Shearwater and Velvet Scoter passed through on the sea and odds and ends on the land included 3 Redwings and singles of Chiffchaff and Redpoll.

Immigrants in the Obs garden moth-traps: 2 Rusty-dot Pearl.

20th November

A strong southerly wind and almost constant rain or drizzle severely restricted fieldwork today. The only reports were of 27 Common Scoter through off the Bill, 13 Common Scoter, 3 Little Gulls and 2 Red-throated Divers through off Chesil Cove and 2 Firecrests at Pennsylvania Castle.

19th November

Although it was windy throughout, the forecast rain took a good deal longer to arrive than we'd expected so there was plenty of opportunity for seawatching. Kittiwakes in particular were trickling through more or less constantly off the Bill, where the pick of the sightings were of 57 Common Scoter, 5 Red-throated Divers, 2 Black-throated Divers, 2 Teal and a Balearic Shearwater passing by. Very little attention was paid to the land, from the where the only news was of 300 Starlings arriving in from the south at the Bill, a Firecrest at Easton and a Black Redstart at Blacknor.

A lone Silver Y was the only immigrant in the Obs garden moth-traps.

      

   

Quail - Portland Bill, 18th November 2012 © Martin Cade

...this hapless individual was discovered in rather peculiar circumstances: well after dark yesterday evening it seemingly crash-landed on the roof of a house extension at Weston; upon investigating the commotion the home-owner found the bird cowering against a wall and took it into care. By the time it came into our hands today it looked to have made a full recovery so we decided to just let it go at the Bill - on release it flew off very strongly into the Crown Estate Field. Quite why a domestic/farm-bred Quail should have been flying over Weston at night at this time of year is open to conjecture, and, since we're always suspicious about such things, leads us to ponder on the provenance of other winter Quail records from Portland.

  18th November

Although dawn had revealed the first light frost of the winter, the day itself was beautifully clear, sunny and increasingly mild. The most extraordinary report of the day concerned two flypasts off the Bill by a Steller's Eider (both sightings from the same observer); after-the-event coverage of the sea there produced 18 Common Scoter, 3 Brent Geese, 2 Red-throated Divers and singles of Great Crested Grebe, Red-necked Grebe and Eider. Not surprisingly given the conditions, grounded migrants weren't at all numerous, with 5 Water Rails, 2 Black Redstarts and a Woodcock providing the only real interest amongst the light scatter of mainly thrushes at the Bill. Equally small numbers of finches were still on the move overhead, with singles of Short-eared Owl, Woodlark and Lapland Bunting providing further interest over the Bill.

A single Red Admiral was still on the wing at the Bill.

Three Silver Y were the only immigrants caught overnight in the Obs garden moth-traps.

      

   

Serin - Portland Bill, 17th November 2012 © Martin Cade

...a right dingy, streaky little thing in the field and only a tad more colourful on closer examination in the hand:

Although clearly a female, we weren't so confident about its age: at first glance it looked likely to be a bird of the year but the more we looked the less confident we were that that was an entirely safe diagnosis:

  17th November

With what wind there was having shifted out of the east and into the north-west there was a good deal less expectancy about proceedings today, but in the event a Serin that showed at the Obs was a nice surprise and kept up the recent run of oddities. The eventual tally of more routine fare wasn't too bad either, with the Bill area coming up with totals of 150 more northbound Starlings, 75 Redwings, 50 Blackbirds, 25 Song Thrushes and 11 Long-tailed Tits, whilst the decent array of single-figure totals included 2 Snipe, 2 Black Redstarts, a Grey Heron and a Mistle Thrush. Elsewhere there were further single Black Redstarts at Blacknor and Portland Castle, a Moorhen at Suckthumb Quarry, a Red-throated Diver in Portland Harbour and 1 of the Black Brants at Ferrybridge. A single passing Red-throated Diver off the Bill was the only bird of interest on the sea.

Immigrants in the Obs garden moth-traps: 4 Rusty-dot Pearl, 4 Silver Y and 1 Rush Veneer.

...also of interest, we received news this week of the continuing presence of a family of Badgers on the Verne Common Estate; thanks to Trevor Felstead for a photo of two of them visiting his garden:

  

  16th November

Despite the conditions seeming just as promising as those of the last couple of days there was considerably less in evidence today. Thrushes were still conspicuous, with counts that included 100 Blackbirds and 50 Redwings at the Bill, but the best of the relatively thin spread of other new arrivals were 10 Bramblings, 9 Lapwings, 4 Snipe, 2 Golden Plovers and a Firecrest at the Bill and a Mistle Thrush at Penn's Weare. Four Brent Geese passed through off the Bill and 1 of the Black Brants were again amongst the brents at Ferrybridge.

  15th November

Portland's late autumn purple patch continued with the discovery of a very obliging Hoopoe in the Osprey Quay area, whilst migrant-wise, with the wind remaining in the east, there was still plenty to entertain. Thrushes, Goldcrests and finches made up the bulk of the numbers at the Bill, where day-totals included 100 Blackbirds, 70 each of Song Thrush, Redwing and Fieldfare, 25 each of Goldcrest and Brambling, 9 Lapwings, 3 Woodcocks, a Snipe and a Black Redstart; of note elsewhere were singles of Woodcock at Easton, Black Redstart at Reap Lane, Firecrest at Pennsylvania Castle and Lapland Bunting over Penn's Weare. The sea also got a fair bit of attention, with 4 Shelduck and singles of Red-throated Diver, Great Northern Diver, Brent Goose, Wigeon, Red-breasted Merganser and Pomarine Skua the pick of the bunch off the Bill.

Immigrants in the Obs garden moth-traps: 2 Rusty-dot Pearl and 1 Delicate.

14th November

The much anticipated return of easterlies certainly saw the numbers perk up, whilst the hot tip for the day - a Pallas's Warbler - duly obliged by dropping in briefly at Verne Common; further rarity interest was provided by the Dusky Warbler that remained at Portland Castle. Northbound Starling passage has been a feature of the last fortnight, and today chipped in with totals of 9860 over Portland Heights, 850 over the Bill and 500 over Portland Castle; small numbers of routine thrushes and finches were also on the move overhead, along with singles of Ringed Plover, Golden Plover and Snipe over the Bill and 2 Snipe and a Mistle Thrush over Portland Heights. On the ground a late flurry of Goldcrests included 10 new birds trapped at the Obs, whilst also of note were 5 Reed Buntings, 3 Woodcock, a Merlin, a Firecrest and a Bullfinch at the Bill, a Merlin at Barelycrates Lane, at least 3 Black Redstarts and 4 Firecrests scattered elsewhere and singles of Black Brant and Pale-bellied Brent Goose at Ferrybridge.

...for a long time views were subliminal at best:

  

...but towards the end of the afternoon, after a decent little burst of calling (click here to have a listen), it became slightly more visible when, rather oddly, it made several visits into the tops of 10m sycamores:

  

The best views came so late that there was almost no light for photography:

  

  13th November

A day that looked to be fizzling out rather uneventfully suddenly came to life in mid-afternoon with the discovery of a typically elusive Dusky Warbler at Portland Castle. Earlier, interest had been restricted to 2 Great Skuas through off the Bill, some light passage of finches over the Bill (including 220 Goldfinches, 80 Linnets and 5 Bramblings), the odd few grounded thrushes, Blackcaps, Chiffchaffs and Goldcrests here and there, Water Rails at Verne Common (8) and the Bill (2) and single Black Redstarts at Blacknor and the Bill.

The lingering party of 10 or more Bottle-nosed Dolphins spent most of the day off East Cliffs at the Bill.

Immigrants in the Obs garden moth-traps: 6 Rusty-dot Pearl and 3 Silver Y.

12th November

More or less constantly drizzly, miserable conditions saw to it that meaningful coverage was out of the question today. Newly arrived thrushes, particularly Blackbirds, were in evidence at the Bill, where odd forays into the field also produced 2 Chiffchaffs, a Merlin and a Goldcrest on the land, 160 Starlings arriving in from the south and a single Red-throated Diver through on the sea.

   Starlings - Portland Bill, 11th November 2012 © Martin Cade

...and we've never had to twitch a Coot before now, but since this is a species that we haven't featured a single photograph of in 12 years of doing the website we thought we ought to make the effort when a decent little flock turned up at Ferrybridge this morning: 

  

  

The Coot must be one of the most consummate of nocturnal migrants that hardly ever makes a mistake and turns up in the wrong place: despite the presence every winter on the nearby Fleet of thousands that migrate to and fro from northern Europe, there have only ever been six records at the Bill - and the last one of those was 31 years ago! These days virtually all of the Portland records are of odd singles or small groups that show up at Ferrybridge/Portland Harbour during spells of severe cold, so today's presumed downed migrants at Ferrybridge were quite noteworthy.

  11th November

In clear, sunny conditions another 3000 or so Starlings arrived from the south but overhead passage was otherwise largely uneventful, with no more than a trickle of expected fare - including a lone Bullfinch - over the Bill. Morsels of interest elsewhere included 2 Firecrests at Pennsylvania Castle, a Black Redstart at Blacknor, singles of Red-throated Diver, Red-necked Grebe and Eider in Portland Harbour and 25 Coots at Ferrybridge.

  10th November

Today's migrant tally remained at a less than impressive level, with single figure totals of the less common thrushes and finches amongst the light trickle of common migrants overhead; a Canada Goose in off the sea at the Bill, single Black Redstarts at the Bill, Reap Lane and Blacknor, and a lone Mistle Thrush grounded at the Bill were the day's only very minor highlights. Despite getting a fair bit of attention the sea produced nothing better than singles of Red-throated Diver and Great Skua through off the Bill, although there were signs of interest picking up in the sheltered waters of Portland Harbour, where 2 each of Great Northern Diver and Black-necked Grebe, and singles of Red-throated Diver and Slavonian Grebe were of interest.

Bottle-nosed Dolphins have been relatively frequent off the Bill in recent days, with a dozen or more lingering off East Cliffs for much of the morning today.

Immigrants in the Obs garden moth-traps: 5 Silver Y and 2 Rusty-dot Pearl.

9th November

With an Atlantic air-flow still well-established there was again little to enthuse about today. The highlights of a fairly mediocre overhead passage were three large flocks of Starlings - totalling c4500 birds - arriving in quick succession in off the sea at the Bill, and a steady (mainly southbound) passage of Chaffinches there that included a sample count of 317 in an hour; a few more of the usual suspects overhead there included 15 Bramblings, 5 Siskins and 4 Fieldfares. Grounded migrants included precious little of note anywhere. A good congregation of Mediterranean Gulls - 200 or so in total - featured off the Bill, where 2 each of Pomarine Skua and Great Skua along with a lone Red-throated Diver also passed by.

Immigrants in the Obs garden moth-traps: 6 Rusty-dot Pearl and 2 Silver Y.

8th November

Poorer by the day this week, with today coming up with no more than the lightest trickle of new arrivals, the majority of which were common thrushes and finches. What little quality there was came in the form of 11 Swallows, 9 Long-tailed Tits, 4 Bramblings and singles of Snipe and Firecrest at the Bill, a Lapland Bunting at Barleycrates Lane, a Firecrest at Suckthumb Quarry and a Black Redstart at Blacknor. The sea wasn't action-packed, but did produce 86 Common Scoter, 2 Red-throated Divers and a Teal through off the Bill; another 2 Red-throated Divers, along with a lone Slavonian Grebe, were in Portland Harbour.

Immigrants in the Obs garden moth-traps: 2 Rusty-dot Pearl and 2 Silver Y.

7th November

West/north-west winds tend to sound the death knell for routine migration at this time of year and, with the notable exception of 2 Lapland Buntings and a Snow Bunting that flew north over the Bill, that certainly proved to be the case today. There were still small numbers of late migrants on the move, but the only moderate interest was provided by the likes of 7 Bramblings and singles of Grey Heron, Snipe, Short-eared Owl, Swallow, Firecrest and Yellowhammer at the Bill and additional mid-island Firecrests at Easton (2) and Avalanche Road. Up to 100 Mediterranean Gull were lingering off the Bill, where 42 Common Scoter, 2 Red-throated Divers and a Pomarine Skua also passed by.

The first moth-trapping for a few nights revealed that were still a few immigrants on the wing, with 6 Silver Y and 2 Rusty-dot Pearl caught at the Obs.

6th November

For the most part a lovely clear, sunny day, with heavy cloud cover eventually rolling in late in the afternoon. Late migrants certainly found the conditions to their liking and there was a steady throughput of new arrivals - most departing just as quickly as they'd shown up. Wood Pigeons were again on the move, with 2000 or so heading south so high over the Bill that it looked likely that many more were missed; in contrast, Starling passage was more visible, with 3000 over the Bill and 2000 over Weston all heading north at low level. Amongst the steady trickle of other migrants at the Bill there were 100 each of Blackbird and Song Thrush, 50 Redwings, 25 Bramblings, 15 Fieldfares, 10 Swallows, 5 Snipe, 5 Redpolls, 3 Reed Buntings, 2 Short-eared Owls, 2 Mistle Thrushes, 2 Firecrests and singles of Grey Heron, Bullfinch and Yellowhammer, whilst elsewhere notable sightings included a Lapland Bunting at Barleycrates Lane, 2 Continental Coal Tits, 2 Mistle Thrushes and a Firecrest Avalanche Road/Suckthumb Quarry and singles of Ring Ouzel and Coal Tit at Penn's Weare. A lone Eider passed through on the sea at the Bill.

5th November

Lots more heavy overnight rain eventually gave way to clearer skies and a good deal of sunshine, along with a welcome shift in wind direction into the north-east. The day's rewards were hardly on a par with those in late October, but there was a good deal more on the move than in recent days. At the Bill the most conspicuous migrants were Lesser Black-backed Gulls, Wood Pigeons and Starlings, all of which were heading in different directions: c300 Lesser Black-backs headed east offshore, c500 Wood Pigeons left to the south and c875 Starlings arrived in off the sea and headed away to the north. Otherwise it was a day of relatively routine northbound passage of mainly thrushes and finches that included 600 Chaffinches, 22 Bramblings, 2 Mistle Thrushes and a Lapland Bunting, whilst the best of the rest were 6 Black Redstarts, 2 Merlins and singles of Lapwing, Snipe, Firecrest and Continental Coal Tit.

4th November

Quite a weather roller-coaster today, with a blasting, cold northerly and rain at dawn, calm, sunny and mild conditions through the middle of the day and then bucketloads of rain through the evening. Although there were a few new arrivals in the poor weather at dawn, more seemed to drop in as the day went on, with mildly respectable totals on the ground at the Bill that included 7 Chiffchaffs, 6 Blackcaps, 6 Bramblings, 4 Goldcrests, 3 Redwings, 3 Fieldfares, 3 Black Redstarts and 3 Firecrests; elsewhere there was a notable total of 14 Black Redstarts at Easton/Weston. Finches - mainly Goldfinches today - were still on the move overhead, and another 2 late Swallows also passed over at the Bill. Three Mallards passed by off the Bill, with the same or another 3 later found settled on floodwater at Reap Lane.

3rd November

Still very samey conditions and birding. The only numbers were overhead, with a continual light southbound passage over the Bill through the morning; a sample one hour count there came up with 1500 Wood Pigeons, 370 Goldfinches, 210 Linnets, 57 Chaffinches, 30 Meadow Pipits, 18 alba wagtails, 4 Bramblings, 2 Swallows and a Siskin. New arrivals on the ground were few and far between, with better weekend coverage probably doing little more than finding more of what had been around for several days: Black Redstarts were at the Bill (2), Weston (2) and Church Ope Cove, 6 Pale-bellied Brent Geese and 2 Black Brants were again at Ferrybridge, and singles of Merlin, Purple Sandpiper, Short-eared Owl and Mistle Thrush also made the log at the Bill. The sea remained disappointingly quiet, with a lone Great Skua providing the only interest off the Bill.

2nd November

Not even a hint of a change in the weather so precious little change in the birding. Despite a general lack of grounded migrants - a late Redstart, a Black Redstart and a Firecrest at Wakeham and further Black Redstarts at the Bill (2) and Weston provided the only real interest - there was a fair bit on the move overhead, with a sample one hour count at the Bill coming up with 360 Goldfinches, 320 Linnets, 120 Wood Pigeons, 110 Starlings, 60 Chaffinches, 25 Greenfinches, 16 alba wagtails and 9 Skylarks. Despite the strength of the wind the only worthwhile sighting from the sea was of a lone Great Northern Diver through off the Bill.

 

Also, thanks to Dr Martin Collinson at the University of Aberdeen for letting us know that mtDNA extracted from feather samples of last week's Siberian Stonechat confirm that it belongs to the form stejnegeri; fuller details will follow in due course.

1st November

With a stiff westerly firmly established there were low expectations which were only just exceeded by the day's happenings. The thin scatter of grounded migrants included some interest in the form of singles of Ring Ouzel at Penn's Weare and Wakeham, Firecrest at the Bill, Perryfields, Penn's Weare and Easton, and Black Redstart and Bullfinch at the Bill; small numbers of finches were on the move overhead, with a short sample count at the Bill coming up with totals of 240 Goldfinch, 180 Linnets and 40 Chafffinches. The only other news was of the continued presence of the Red-throated Diver at Portland Harbour/Ferrybridge.

A lone Rush Veneer was the only immigrant moth caught overnight at the Obs.

October 2012

31st October

An undistinguished and at times really quite miserable end to a fabulous month, as a blasting westerly blew through a constant succession of heavy showers. At least 1 of the Black Brants was again at Ferrybridge, whilst the tiny handful of grounded migrants at the Bill included nothing more interesting than 3 Siskins.

Singles of Diamond-back Moth, Pearly Underwing and Silver Y were the only immigrants in the Obs garden moth-traps.

The grim conditions kept Peter Morgan indoors for much of the day, where he took the opportunity to get the ringing totals up to date. This month's Obs garden/Crown Estate Field total ended up on a rather staggering 2274: we haven't got the all-time totals to hand but we can't remember a month before this one when the 2000 mark has been exceeded. Of particular note within this total were a remarkable 400 Robins: the previous highest annual Robin total was 262 in 1998.

  30th October

A lovely still, mild and sunny late autumn day. Passage was much as would be expected given the conditions, with small numbers of routine finches - including low double figure totals of Brambling, Siskin and Redpoll - dominating at the Bill; the best of the rest there were 8 Black Redstarts, 3 Purple Sandpipers, 3 Firecrests, a Ring Ouzel, a Continental Coal Tit, a Bullfinch and a Yellowhammer. Elsewhere, the Dark-bellied Brent Goose total at Ferrybridge increased to 1370, with 176 Mediterranean Gulls, 6 Pale-bellied Brents, 2-3 Black Brants and 2 Mute Swans also present there, whilst nearby a Red-throated Diver was in Portland Harbour. The only seawatch reports were of 3 Brent Geese and singles of Red-throated Diver and Great Northern Diver through off the Bill.

  29th October

How the mighty doth fall: last week Portland was on fire but today it was resoundingly back down to earth with a bump as a stiff south-westerly and frequent heavy showers put the block on migration. That said, there was a major local highlight in the form of a settled Pink-footed Goose that pitched up amongst the brents at Ferrybridge; 6 Pale-bellied Brents and 2 Black Brants were also among the flock. Passerine-wise it was pretty dreadful, with tiny numbers of routine fare and just 2 Black Redstarts at the Bill by way of quality. The sea was disappointingly quiet, with nothing more than 2 Manx Shearwaters through off the Bill.

 

 

A reminder that the next In Focus field event at the Obs takes place between 10am and 4pm tomorrow, Tuesday 30th October.

  28th October

Although there were a scatter of new arrivals it was extremely quiet in comparison with recent days, and it seems as though the good times are fizzling out now that the wind has returned to the west. Today's only particularly out of the ordinary sighting concerned a Siberian Chiffchaff at Easton; otherwise interest was restricted to a light scatter of Ring Ouzels, Black Redstarts and Firecrests everywhere, 2 Short-eared Owls at the Bill, a Woodcock at Suckthumb Quarry and, amongst the generally small numbers of commoner migrants, a short, sharp movement of 3000 Wood Pigeons over the Bill. The sea got more attention than of late, with wildfowl getting going to a limited extent off the Bill, where 84 Common Scoter, 37 Wigeon, 8 Teal and 3 Velvet Scoter passed by and 3 Eider were settled offshore.

  27th October

After a much colder night that saw the skies clear for the first time this week it was perhaps a surprise that the Daurian Shrike was still present; the Siberian Stonechat had moved on though, and there was also no sign of the Subalpine Warbler; at least 2 Long-eared Owls at the Bill included a new arrival that arrived in off the sea, whilst a Barred Warbler at Culverwell may or may not have been the bird last seen there a few days ago. Additionally, an Egyptian Vulture - thought likely to the the wide-ranging escapee last reported in Norfolk a fortnight ago - was seen briefly high over the north of the island. Notable events on the common migrant front included a strong passage of Wood Pigeons (including 7000+ over the Bill and 3000 over the centre of the island), together with a good spread of the likes of Ring Ouzels and Black Redstarts. Fuller update to follow later.

...with some perseverence - it was b****y cold and damp sitting in the middle of an open field for several hours - it was trapped today. The well-saturated plumage speaks for itself; biometric-wise, the only useful measurement is supposed to be bill width (proximal end of nostrils) which came out at a rather unhelpful middle of the road 4.9mm (a minimum figure; this isn't that easy a measurement to take on a live bird so two of us did several re-checks which were all in the range 4.9-5.0 mm). This'll be another story that runs and runs...

  26th October

In the early hours of the morning there was a surprise in the form of a Stone Curlew heard calling over the Obs; click here to listen to a recording of it. On a colder, damper day most of the quality remained in situ, with the Daurian Shrike, Siberian Stonechat and at least 1 Long-eared Owl still at the Bill; also not altogether surprising was the rediscovery of the Subalpine Warbler a couple of hundred metres from Avalanche Road at the former Weston Craft Centre. Amongst plenty more routine fare, new arrivals at the Bill included the likes of 10 Ring Ouzels and 1 or 2 Wrynecks, whilst elsewhere there were 10 Ring Ouzels at Suckthumb Quarry, a late Wood Warbler at Avalanche Road and more Ring Ouzels, Black Redstarts and Firecrests dotted around the island, A fuller report to follow in due course.

With the easterly wind having freshened noticeably, birding was often not so easy today. That said, yesterday's putative Siberian Stonechat was quickly rediscovered and confirmed near Culverwell, 2 Long-eared Owls put in an appearance in the Hut Fields area, the Daurian Shrike remained in Top Fields and a new Siberian Chiffchaff showed up at Wakeham. Routine migrants were still passing through in quantity: thrushes were not quite so numerous as in recent days, but Chaffinches in particular were on the move throughout the morning; uncommon migrants at the Bill included 10 Black Redstarts, 3 Ring Ouzels, 2 Woodcock and a Short-eared Owl.

What an excellent spell of birding this has been, with migrants still on the move in really impressive numbers today. We're just not finding enough time to be able to give full reports at the moment but today's highlights included the Daurian Shrike which eventually settled and showed well in Top Fields, a Wryneck and a Long-eared Owl in the Bill Quarry/QinetiQ compound area, singles of Siberian Chiffchaff and Yellow-browed Warbler at Southwell and, at last light, a likely Siberian Stonechat seen briefly near Culverwell. Amongst the many hundreds of thrushes, Robins, finches and the like passing through the Bill area there were noteworthy totals of 25 Black Redstarts, 8 Ring Ouzels, 8 Short-eared Owls and 3 Woodcock. 

Immigrants in the Obs garden moth-traps: 35 Rusty-dot Pearl, 27 Silver Y, 16 Rush Veneer, 2 Dark Sword Grass, 2 Scarce Bordered Straw, 1 Pearly Underwing and 1 Delicate; elsewhere, another Flame Brocade was the pick of the overnight moth catch at Southwell.

  23rd October

The continuing murky, easterly conditions produced another hatful of migrants, amongst which a Daurian Shrike frequenting the fields either side of the Bill Road was a fine highlight. We'll come back to the numbers of common migrants on a later update, but for the time being the list of scarcities included 10 Black Redstarts, 5 Ring Ouzels, 2 Woodcock, 2 Short-eared Owls, a Wryneck, a Woodlark, a Yellow-browed Warbler and the Barred Warbler at the Bill and 2 Yellow-browed Warblers and a Siberian Chiffchaff at Southwell.

Immigrants in the Obs garden moth-traps: 18 Rusty-dot Pearl, 8 Silver Y, 6 Rush Veneer, 2 Pearly Underwing and 1 Dark Sword Grass; elsewhere, another Flame Brocade was caught at the Grove.

      

   

  

  

Further news for today, Monday 22nd, when a Pale-legged or Sakhalin Leaf Warbler was present during the afternoon in a private garden at Southwell. General access was not possible at the time, but once the identification was established after scrutiny of photographs during the evening an agreement was reached that PBO could attempt to trap the bird in the morning with a view to relocating it to a nearby site where access would be possible; unfortunately it was not present on Tuesday and has not been seen since (photos © Pete Saunders)

Postscript: it seems highly likely that, since the bird was not critically examined in the hand, it will never be possible to specifically identify it with certainty. Paul Leader has very kindly communicated to us his initial thoughts which slightly favour SLW; these include:

Plumage-wise, there is nothing to choose as the two species are extremely similar.

Structurally, the apparent relatively long primary projection may be a pro-SLW feature.

In terms of range there is little to choose: although PLLW breeds further west (around 7100 km from Portland), the bulk of the breeding grounds are further east at 7400-8500 km away; Hokkaido/Sakhalin are approx. 8300-9100 km from Portland.

 SLW is on average a later migrant through Hong Kong.

On the breeding grounds SLW is highly arboreal, singing in the canopy, whereas PLLW is generally a low-level skulker (the Southwell bird spent most of its time relatively high up a sycamore in eg Yellow-browed Warbler fashion).

  22nd October

Top-notch migration watching today with overnight rain coupled with dreary skies and fog through the day dropping a constant succession of mainly thrushes and finches around the centre and south of the island. Nothing much lingered for long but the spectacle of flocks of birds dropping out of the murk and heading away northwards was certainly memorable; we haven't yet got a full handle on numbers from the various fieldworkers but there must have been getting on for 1000 each of Blackbird and Chaffinch, together with totals of well into the hundreds of, for example, Redwing and Song Thrush. Among the spread of oddities through this area there were 16 Lapwings, 10 Ring Ouzels, 10 Black Redstarts, 6 Yellow-browed Warbler, 5 Snipe, 4 Tree Pipits, 4 Redstarts, 2 Merlins, 2 Yellow Wagtails, 2 Mistle Thrushes, 2 Reed Warblers, a Woodcock, a Garden Warbler, a Willow Warbler, a Siberian Chiffchaff and a Hawfinch, together with the Barred Warbler that remained at Culverwell.

Immigrants in the Obs garden moth-traps: 4 Rusty-dot Pearl, 4 Silver Y, 2 Delicate and a Dark Sword Grass.

  21st October

There was a distinct air of anticipation about proceedings today, mainly borne out of the enticing mix of overcast skies and easterly wind. As it was, the day's highlights largely involved lingerers, with the Subalpine Warbler still at Avalanche Road and the ever-elusive Barred Warbler glimpsed on odd occasions at Culverwell; new arrivals included singles of Woodlark and Lapland Bunting at the Bill and another Woodlark over Verne Common. Although there was a scatter of the likes of Chiffchaffs and Goldcrests on the ground, most the day's routine passage involved migrants overflying or dropping in only briefly: thrushes were conspicuous at dawn, including more than 100 Song Thrushes headed north over the Bill/Southwell, whilst Pied Wagtails and a variety of common finches were also conspicuous at this time; later arrivals included more than 400 Wood Pigeons over the north of the island and the Bill and the first signs of Starlings arriving from the south (including 105 over the Bill). Among the variety of less frequent/late migrants there were 3 Black Redstarts and singles of Merlin, Snipe and Mistle Thrush at the Bill, a Whinchat at Reap Lane, a Garden Warbler at Avalanche Road, a Redstart at Easton and a Lesser Whitethroat at Verne Common. A Great Northern Diver passed through off the Bill, where the very confiding Red-throated Diver was also still settled off East Cliffs.

Immigrant moths in the Obs garden moth-traps: 9 Rusty-dot Pearl, 3 Dark Sword Grass, 2 Rush Veneer, 2 Delicate, a Pearly Underwing and a Silver Y; elsewhere visiting moth-trappers caught another Flame Brocade at Freshwater Bay.

      

   

  Subalpine Warbler - Avalanche Road, 20th October 2012 © Martin Cade

...it looking to be as much at home feeding high in sycamores as it was in lower cover, and it was quite a little chameleon - constantly taking on apparently different guises as the light changed:

  

  

We were a bit concerned that the boldness of the submoustachial, the richness of the saturation on the underparts (at least in some lights) and amount of white on the outer tail feathers were not altogether compatible with the idea that it was most likely a first-winter male:

  

...but on closer examination the tail pattern at least looks to rule out any possibility of it being, for example, a well-marked adult female.

  

And whilst searching for the Subalp after it disappeared we had the mildly disconcerting experience of stumbling across this late reed warbler-type lurking deep in cover (these days you're supposed to relish these experiences and make out that you're always learning or some such thing, but more often our heart sinks and we ponder on how much easier it would be if we'd got it in the hand):

Anyway, eventually it did deign to pop out in the open whereupon it looked a lot less interesting:

...and a few calls - click here to have a listen - finally confirmed it really was just a Reed Warbler. Incidentally, if you think that something calling a bit shorter and sharper than this is going to be a Blyth's Reed, have a listen to these Marsh Warblers that we recorded last autumn in Kenya.

  20th October

Lovely and calm again today, with the rediscovery of the Subalpine Warbler at Avalanche Road (after nearly a week of being overlooked) providing compensation for the general dearth of common migrants; a Wryneck was a new arrival at Southwell, the Culverwell Barred Warbler was still present, whilst further interest was provided by the likes of a scatter of Firecrests, single Ring Ouzels at Southwell and Broadcroft Quarry, and a Woodlark over the Bill. Grounded common migrants included all the usual suspects in rather small numbers, along with late singles of Reed Warbler at Avalanche Road and Lesser Whitethroat at Verne Common, whilst overhead 300 Wood Pigeons and 100 Jackdaws were noteworthy amongst the trickle of routine fare. A settled Red-throated Diver off East Cliffs at the Bill was the only notable sighting on the sea.

Immigrants in the Obs garden moth-traps: 17 Rusty-dot Pearl, 10 Rush Veneer, 5 Silver Y, 3 Delicate and 1 Flame Brocade; another Flame Brocade was the pick of the catch at the Grove.

  19th Octobe

After several days of far too much wind and far too few migrants it was very welcome indeed to wake to a calm, heavily overcast dawn, when it was quickly apparent that there was plenty about. In truth, variety was a little disappointing, with Goldcrests by far the most numerous new arrivals: a good 150 were at the Bill, whilst plenty more were scattered throughout suitable cover elsewhere; Blackcaps and Chiffchaffs were well spread without being especially numerous, whilst Pied Wagtails and various common finches made up the bulk of the rest of the numbers on the ground. A surprise was the reappearance of the Culverwell Barred Warbler which turned up out of the blue in a mist-net having escaped notice for a couple of days; other interest was provided by 6 Firecrests, a Merlin, a Short-eared Owl and late singles of Whinchat and Willow Warbler at the Bill, a Great Spotted Woodpecker at Southwell, 2 more Firecrests and another Great Spotted Woodpecker at Easton and a Ring Ouzel at West Weare. An early passing Little Auk was an unexpected highlight on the sea at the Bill, where a lone Balearic Shearwater also passed by.

The moth-traps were much busier overnight, with the immigrant tally at the Obs consisting of 14 Rusty-dot Pearl, 12 Rush Veneer, 6 Delicate, 3 Silver Y, a Diamond-back Moth and a Dark Sword Grass; elsewhere, single Flame Brocades were caught at Southwell and the Grove.

...it seems as though the brents have had a very poor breeding season, with no juveniles present amongst the 900 or so Dark-bellied Brents present when this photo was taken earlier in the week.

    18th October

The brisk south-westerly wind remained a feature all day and, together with some very stormy conditions overnight, looked have put the block on passerine passage for another day. A little interest was salvaged by the seawatchers who logged 4 Balearic Shearwaters, 2 Great Skuas, a Sooty Shearwater and a Pomarine Skua through off the Bill and singles of Great Northern Diver and Little Gull at Chesil Cove. A Continental Coal Tit at Easton was the pick of the day's new arrivals on the land, with 2 Firecrests and a Short-eared Owl at the Bill and another Firecrest at Pennsylvania Castle providing the rest of the day's interest.

Singles of Rush Veneer and Rusty-dot Pearl were the only immigrants caught overnight in the Obs garden moth-traps.

17th October

With the notable exception of a Sabine's Gull that lingered distantly for a little while off Chesil Cove before heading away south and soon afterwards being picked up as it rounded the Bill, today's blustery south-westerlies weren't conducive to perking up interest. Most attention was given to the sea, but the only worthwhile reports from the Bill were of 12 Common Scoter, 3 Great Skuas and singles of Red-throated Diver, Manx Shearwater, Arctic Skua and Sandwich Tern passing by. The land came up with a Merlin at the Bill and a very light sprinkle of routine grounded migrants everywhere.

Four Rush Veneer were the only immigrants caught overnight in the Obs garden moth-traps.

16th October

For the most part, comprehensively dismal today with few if any new arrivals on the ground, only the mearest trickle of migrants on the move overhead and precious little through on the sea. The Barred Warbler remained at Culverwell although in the strong westerly wind its appearances were as infrequent as ever, whilst 2 Short-eared Owls and a Merlin at the Bill, a Firecrest at Grove Point and a Great Spotted Woodpecker at Easton were the day's only uncommon migrants. The only seawatch reports were of 4 Brent Geese, 2 Common Scoter and 2 Great Skuas through off the Bill.

Immigrants in the Obs garden moth-traps: 5 Rush Veneer and 1 Diamond-back Moth.

    15th October

The forecast of a rain front passing over south-west England during the night had looked mildly promising but it was quickly apparent in the brisk north-westerlies and clear skies of dawn that new arrivals weren't at all prominent. Some surprise pigeon movement was evident at the Bill, where 1400 Wood Pigeons and 90 Stock Doves arrived from the north, but in the absence of any other worthwhile numbers of common migrants the day's interest stemmed largely from the list of oddities : the ever-elusive Barred Warbler, 2 Merlins, 2 Ring Ouzels, 2 Firecrests and a Short-eared Owl at the Bill, singles of Balearic Shearwater, Great Skua and Arctic Skua through on the sea there, a Woodlark over Avalanche Road and a Yellow-browed Warbler at Foundry Close. Elsewhere, brent goose numbers continued to build up at Ferrybridge, where 900 Dark-bellied Brents and a lone Pale-bellied Brent were counted this morning.

Immigrant moths were a little more mumerous, with 19 Rush Veneer, 9 Silver Y, a Delicate and a White-speck caught overnight in the Obs garden traps.

14th October

With little change in the weather it was maybe not a surprise that there wasn't a significant arrival of new grounded migrants, however, amongst those that did drop in there was a notable find in the form of a Subalpine Warbler that made a brief visit to Avalanche Road before seemingly disappearing towards Coombefield Quarry. A Wryneck equally briefly in Top Fields was also new, the Culverwell Barred Warbler finally gave itself up to those willing to put in the time, the Yellow-browed Warbler remained at New Ground, whilst noteworthy scarce migrants included Woodlarks at Avalanche Road (2) and over the Bill, 10 Ring Ouzels at West Weare, singles of Merlin and Great Spotted Woodpecker at the Bill and several Firecrests dotted around the areas of cover. Pied Wagtails, Meadow Pipits, Blackcaps, Chiffchaffs and Goldcrests were again the most conspicuous commoner migrants on the ground, whilst a rather subdued overhead passage was dominated by a typical mix of hirundines, finches and the like.

Immigrants in the Obs garden moth-traps: 3 Silver Y and singles of Dark Sword Grass, Pearly Underwing and Delicate.

13th October

North-westerlies and, bar a couple of early and late showers, mainly clear skies again today. Another small arrival of Yellow-browed Warblers saw singles found early in the morning at New Ground, the Eight Kings Quarry and in a private garden at Southwell; Firecrests were also well-represented, with 10 or more scattered around the centre and south of the island amongst a small arrival of more new Robins, Blackcaps, Chiffchaffs and Goldcrests. Variety on the ground was otherwise not too great, but did include 3 Willow Warblers, 2 Whinchats, 2 Reed Buntings and singles of Merlin, Water Rail, Redstart, Black Redstart and Spotted Flycatcher at the Bill. Passage was a good deal stronger overhead, with 400 alba wagtails, 200 Wood Pigeons, 50 Siskins, 2 Grey Wagtails, 2 Tree Pipits, 2 Bramblings and a Redpoll amongst the plentiful Meadow Pipits and commoner finches over the Bill. Seawatching at the Bill produced 50 Dunlin, 7 Balearic Shearwaters and an Arctic Skua through off the Bill, where more than 150 Mediterranean Gulls were lingering offshore.

The first Clouded Yellow for several weeks was seen at the Obs Quarry.

12th October

A complete change in the weather - this week's easterlies and dreary skies were replaced overnight by brisk north-westerlies - saw migrant interest largely fizzle out. There were still a few new arrivals and a handful of lingerers but quality didn't get beyond a couple of glimpses of what apparently looked likely to be the Barred Warbler at Culverwell, a scatter of Firecrests - including 3 at the Obs, 2 at Culverwell and 2 at Grove Point - and the likes of a lone Merlin at the Bill. Numbers on the ground were much reduced, but still included a fair spread of Blackcaps, Chiffchaffs and Goldcrests everywhere, whilst a scatter of tardy migrants included singles of Yellow Wagtail, Tree Pipit, Reed Warbler and Spotted Flycatcher at the Bill. Two Balearic Shearwaters were lingering off the Bill, where a lone Arctic Tern also passed by.

    11th October

Another heavy downpour in the late hours of the night dropped plenty more migrants, with the highlights being a rather elusive Barred Warbler at Culverwell and at least 2 new Yellow-browed Warblers - at the Obs and Ladymead, Easton - to add to 1 at Weston Street that was perhaps lingering on from a couple of days ago. The pick of the more routine fare included lots more of the likes of Robins, thrushes, Blackcaps, Chiffchaffs, Goldcrests and finches, amongst which 15 Bramblings, 7 Whinchats, 5 Redstarts, 2 Firecrests, a Merlin, a Barn Owl, a Lesser Whitethroat and a Yellowhammer at the Bill, a Ring Ouzel a Avalanche Road, a Black Redstart at Barleycrates Lane, a Hobby, a Ring Ouzel and a Firecrest at East Weare and a Hobby at Castletown were of particular note. Singles of Great Northern Diver, Wigeon and Arctic Skua passed through off the Bill, whilst 18 Sandwich Terns were still at Ferrybridge.

The overnight immigrant moth catch at the Obs consisted of 13 Silver Y, 10 Rush Veneer, 7 Dark Sword Grass, 5 Rusty-dot Pearl and a Scarce Bordered Straw, whilst by day single Hummingbird Hawk-moths were at the Obs and Weston.

10th October

With overcast skies and the wind still firmly in the east there was another nice arrival of migrants throughout the island today. Yellow-browed Warblers were again the only minor oddities to put in an appearance, with at least 3 remaining in the Southwell area and likely new arrivals showing up at Wakeham and the Grove (click here to listen to a short recording - made with the phone as we didn't have any proper gear with us - of the latter bird calling just before dusk). The back-up array of commoner fare included another substantial fall of Robins - including 100 or more at the Bill - together with a good spread of the likes of thrushes, Blackcaps, Chiffchaffs and Goldcrests, whilst uncommon migrants included 5 Firecrests, 4 Bramblings and singles of Little Egret, Merlin and Black Redstart at the Bill, and another 5 or so Firecrest, 2 Crossbills and a Mistle Thrush around the centre of the island; unexpectedly late migrants still figured with, for example, getting on for 10 each of Redstart and Willow Warbler, and 2 Spotted Flycatchers scattered about. The sea got more attention than of late, with a strong eastward movement of Lesser Black-backed Gulls off the Bill being of note; at least 31 Mediterranean Gulls and 6 Sandwich Terns were also feeding off there, whilst singles of Red-throated Diver, Great Skua and Arctic Skua also passed by/lingered; up to 28 Sandwich Terns (together with the first three figure total of Dark-bellied Brent Geese of the autumn) were also settled at Ferrybridge.

A small party of Bottle-nosed Dolphins headed north off East Cliffs/Penn's Weare during the morning.

Windy conditions hampered overnight moth-trapping, with the immigrant totals at the Obs reduced to just 20 Rush Veneer, 9 Silver Y, 2 each of Dark Sword Grass, Pearly Underwing and Delicate, and a single Rusty-dot Pearl.

...before eventually showing a lot better:

  

  9th October

A second day of almost continual rain or drizzle saw many of the well-walked pathways begin to resemble a scene from a Passchendaele re-enactment; however, trench-foot aside, there were plenty of rewards for those that braved the mud. Yellow-browed Warblers again featured strongly, with 5 in the Southwell area and at least 1 at the Obs, whilst notable amongst a wide array of uncommoner migrants were 10 Bramblings, 3 Golden Plovers, 3 Whinchats, 3 Firecrests, 2 Snipe, 2 Redstarts, 2 Black Redstarts and singles of Hobby, Water Rail and Mistle Thrush at the Bill, a Firecrest at Avalanche Road, a Pied Flycatcher at Reap Lane, 2 Ring Ouzels at Penn's Weare and a Merlin at Ferrybridge. Robins, Blackcaps, Chiffchaffs and Goldcrests again all figured strongly amongst the routine fare on the ground, whilst there were surprisingly conspicuous pulses of visible passage overhead, notably including good totals of Skylarks, House Martins and Chaffinches over the Bill.

An overnight pause in the rain, accompanied by a decent temperature and virtually no wind, saw the various moth-traps get much busier than they have been of late, with newly arrived immigrants particularly conspicuous. The Obs garden traps came up with totals of 163 Rush Veneer, 60 Angle Shades, 22 Rusty-dot Pearl, 21 Silver Y, 15 Delicate, 5 Dark Sword Grass and singles of Spoladea recurvalis, Dark Spectacle and Red Admiral butterfly; elsewhere there were 2 Delicates at both Southwell and the Grove, with the latter also chipping in with 2 more Flame Brocades.

      

   

  

Yellow-browed Warblers - Portland Bill, 8th October 2012 © Martin Cade

...the two Yellow-browed Warblers trapped and ringed at the Obs today. The change in this species' status has been remarkable: in the early days of PBO it took six years of fieldwork before Yellow-browed Warbler was even added to the island list (the first for Portland - in 1960 - was also the first record for Dorset), and another two decades passed before the island total got beyond 10. The all-time total now stands at somewhere only a little shy of 250, with the species considered to be nothing less than an expected scarce migrant. 

  8th October

Another excellent day today, although quite different to the two clear, dry weekend days. The wind remained in the east but rain and fog that arrived during the hours of darkness dropped a fine and varied arrival of new migrants throughout the island - noteworthy amongst which were tremendous numbers of Robins, at least 5 Yellow-browed Warblers (3 at the Bill and 2 at Southwell), a Coal Tit (at Culverwell), the first conspicuous arrival of thrushes of the autumn and unexpected numbers of several late common migrants. The centre and south of the island got the lion's share of the coverage, which was always hampered by poor visibility and spells of drizzle: Robins numbered around 200 at the Bill, and were described as more numerous around the centre of the island than one observer with many year's experience had ever seen before; selected other totals for these areas included 200 Chiffchaffs, 70 Blackcaps, 50 Blackbirds, 40 Song Thrushes, 40 Goldcrests, 25 Redwings, 17 Bramblings, 13 Redstarts, 10 Whinchats, 10 Willow Warblers, 5 Pied Flycatchers, 4 Black Redstarts, 4 Firecrests and 3 Reed Warblers.

    7th October

A day of quantity rather than quality, with all of yesterday's oddities having moved on during a clear, moonlit night. Northbound overhead passage was very conspicuous throughout the island during the first few hours of the morning, when sample counts included 1200 House Martins, 450 Swallows and 11 Chaffinches in an hour at the Bill, 385 Linnets, 277 alba wagtails, 249 Meadow Pipits and 222 Swallows in 30 minutes at Portland Heights and 115 Siskins over the centre of the island; the wide selection of other species logged during this period included a Spoonbill over the Bill, a Jay at Foundry Close, at least 4 Great Spotted Woodpeckers around the centre and south of the island and a scatter of the first few Redwings and 2 Bramblings of the autumn. Grounded/off-passage migrants were also numerous, with 75 Chiffchaffs and 50 each of Blackcap and Goldcrest at the Bill, where there were also around 700 Linnets still present.

Red Admiral passage was again evident, with a steady eastward movement noted throughout the day at the Bill/Southwell.

Immigrants in the Obs garden moth-traps: 6 Silver Y, 3 Rusty-dot Pearl and 1 White-speck; a Flame Brocade at the Grove was the pick of the overnight catches in the various garden traps.

...and a few more random images from the day. Linnets were the most conspicuous migrants at the Bill, where flocks of many hundreds were continually swirling overhead and around the various crop fields:

  

  

  

...Meadow Pipits were logged in their hundreds on the ground and thousands overhead:

  

...a constant succession of east-bound Red Admirals were a feature throughout the day:

  

...and finally, two images of absolutely no merit beyond showing that there was something looking vaguely like a small bunting lurking in the hedge beyond the Eight Kings Quarry; through the 'scope it was possible to make out it was the Little Bunting that Nigel Pleass had done really well to notice whilst he was looking for the nearby Red-backed Shrike - unfortunately it was 100m too far away to photograph properly:

      

  6th October

October at its best today, with an overdue easterly wind and sunny skies, three half-decent rarities, several scarce migrants and plenty of routine fare both on the ground and overhead. The oddities proved troublesome to get to grips with: 2 Great White Egrets flew rapidly south-east over the Bill during the morning, the autumn's second Little Bunting showed only for a short while late in the afternoon near the Eight Kings Quarry, the nearby long-staying Red-backed Shrike was always elusive, whilst none of the 4 Yellow-browed Warblers - 2 in a private garden at Southwell, another trapped and ringed at the Obs and one heard calling at Perryfields - was straightforward. Common migrants were much more plentiful than of late, with, for example, 2000 Meadow Pipits east over the centre of the island, 1000 off-passage Linnets at the Bill and 50-100 each of Blackcap, Chiffchaff and Goldcrest scattered around patches of cover in the centre and south of the island; less frequent migrants included the likes of 3 Grasshopper Warblers, 2 Merlins and a Firecrest at the Bill. Seawatching at the Bill produced 28 Common Scoter and 2 each of Balearic Shearwater, Dark-bellied Brent Goose and Great Skua.

A strong east/south-east passage of some hundreds of Red Admirals was evident at the Bill throughout the day.

    5th October

Although there are promises of fairer conditions for the weekend, today brought plenty more rainfall - first during the early hours when it was accompanied by a brief but quite  severe gale, and later during the afternoon and evening. The grim overnight conditions were enough to put a stop to passage then, with few new arrivals evident on the ground at dawn; however, visible passage soon got going and there were strong movements of hirundines, alba wagtails, Meadow Pipits and Linnets in particular throughout the daylight hours. The Red-backed Shrike begun a second week of residence at Southwell, but oddities were otherwise confined to singles of Firecrest at the Obs, Lapland Bunting overhead at the Bill and Curlew Sandpiper still at Ferrybridge; additionally, another 19 Balearic Shearwaters passed through on the sea at the Bill.

The first Flame Brocade of the autumn was caught overnight by a visiting moth-trapper at the Grove; singles of Hummingbird Hawk-moth and Dark Sword Grass were the only immigrants caught in the Obs traps.

4th October

A much finer day than the last few although the stiff westerly wind was a constant feature. Overhead passage was conspicuous throughout the morning, with a 50 minute sample count at the Bill coming up with totals that included 270 Linnets, 220 Meadow Pipits, 130 Goldfinches, 129 alba wagtails, 55 Swallows, 13 Chaffinches and single figure totals of Merlin, Grey Plover, Grey Wagtail, Tree Pipit and Siskin; Swallow numbers picked up towards midday when more than 300/hour were heading south along the east side of the island. It was quieter on the ground, although the Bill Wheatear total got to around 75, whilst amongst the light scatter of Blackcaps, Chiffchaffs and Goldcrests there were single Firecrests at The Bill and Wakeham, and late-ish singles of Sedge Warbler and Whitethroat at the Bill and Spotted Flycatcher at Pennsylvania Castle; the Southwell Red-backed Shrike was also reported at least once during the day. The only news from the sea was of 7 Balearic Shearwaters and a single Great Skua through off the Bill.

After yesterday's events the continuing unsettled conditions ensured that there was a strong turn out of seawatchers at the Bill; unfortunately it was very quickly apparent that passage had largely fizzled out and was limited to a trickle of Balearic Shearwaters - a total of 39 passed through during the day; the only other worthwhile sighting from there was a single Arctic Skua. There was also a sad lack of numbers on the land: the Red-backed Shrike remained at Southwell, with a second individual reported from Cheyne Weare, but the only other slightly noteworthy sightings were of 3 Siskins at Southwell, a Turtle Dove at Wakeham and a Firecrest at Weston.

  2nd October

Somewhat out of the blue, since the sea has been relatively quiet in recent days, today's fresh westerly and occasional showers saw a decent down-Channel passage of shearwaters develop, with 80 Balearics and 60 Sootys logged at the Bill; although Gannets were well represented there was surprisingly little else on the move, with 14 Common Scoter, 3 Great Skuas and a lone Manx Shearwater the only other worthwhile sightings at the Bill, and singles of Balearic Shearwater, Little Gull and Great Skua the only birds of note at Chesil Cove. On the land the Red-backed Shrike was still present at Southwell and a Curlew Sandpiper was still at Ferrybridge, but apart from 2 Merlins at the Bill there was precious little else worth mentioning.

1st October

An inauspicious start to the new month saw the unsettled theme continued with quite long spells of rain during the later hours of the night and again during the mid/late morning - conditions that look to be putting the block on any sort of sustained passage. Today's disappointing list of grounded migrants at the Bill saw even the likes of Wheatear, Blackcap and Chiffchaff struggle to get beyond the 10-20 mark; the Red-backed Shrike remained at Southwell and a Curlew Sandpiper was still at Ferrybridge but there was precious little else of quality worth a mention. Hirundines in particular were still passing through in decent numbers but 15 Siskins were the only worthwhile extras amongst the limited array overhead at the Bill. Seawatching came up with 22 Balearic Shearwaters, 20 Common Scoter and a Great Skua through off the Bill, whilst also on the water a Red-necked Grebe was settled in Portland Harbour.
