  September 30th

The sea came up with most of today's interest with 33 Common Scoter, 7 Little Gulls, 4 Brent Geese, 3 each of Grey Plover and Arctic Tern, 2 each of Balearic Shearwater, Arctic Skua and Great Skua and singles of Sooty Shearwater and Teal passing through off the Bill. Fair numbers of hirundines and Meadow Pipits were on the move over the Bill but grounded migrants were much more thinly spread than in recent days and the only scarcer species logged were 4 Firecrests, 2 Ring Ouzels, a Hobby and a Merlin at the Bill, a Great Spotted Woodpecker at Southwell and a Merlin at Verne Common.

The overnight immigrant tally in the Obs garden moth traps consisted of 7 Rusty-dot Pearl, 2 Delicate and a single Dark Sword Grass.

  September 29th

Yesterday's 3 Yellow-browed Warblers were all still present and a Red-breasted Flycatcher was a new arrival at Southwell School. Commoner migrants were a little less plentiful than yesterday but still included 100 Blackcaps and 60 Chiffchaffs at the Bill, whilst scarcer migrants included 11 Ring Ouzels, 3 Firecrests, 2 Pied Flycatchers, a Hobby, a Great Spotted Woodpecker, a Black Redstart and a Mistle Thrush scattered around the Bill/Southwell area.

....Robins can be surprisingly tricky to age in the field once they've lost the last vestiges of spotty juvenile plumage. Confusingly, adults frequently exhibit quite conspicuous pale tips to the greater-coverts - a feature usually associated with first year plumage in some of the other chats; however, if present, these tips take the form of narrow rufous wedges rather than the broad buffish spots found in first years. Tail feather shape (broad and rounded in adults, narrow and pointed in first years) provides a relatively safe separation of the age classes, as does leg colour (pale in adults, darker in first years); whilst at a more esoteric level ringers can try their hand at examining the colour of the inside of the upper mandible (blackish in adults, yellowish in first years).

  September 28th

With the north-easterly wind remaining in place there were lots more common migrants along with some quality in the form of 3 Yellow-browed Warblers (2 at Culverwell and another at Southwell) and a Red Kite leaving to the south over the Bill. On the ground Blackcaps and Chiffchaffs dominated with around 100 of each in the Bill area, whilst overhead thrushes were conspicuous for the first time with 60 Song Thrushes and 30 Redwings passing through at the Bill. The first Bramblings of the autumn included 8 through at the Bill and another over Barelycrates Lane and other less common migrants included 44 Siskins, 2 Golden Plover, a Merlin, a Yellow-legged Gull, a Short-eared Owl, a Grasshopper Warbler and a Firecrest at the Bill.

Overnight moth-trapping at the Bill produced just 4 immigrants: 3 Silver Y and a lone Dark Sword Grass.

  September 27th

Another nice day with plenty to see without there being any particular highlight. Most of the centre and south of the island was well covered and returned totals of, for example, 150 Chiffchaffs, 80 Blackcaps, 65 Stonechats, 50+ Robins and 30 Goldcrests along with smaller numbers of most of the other expected late September migrants including 4 Firecrests, the first 3 Redwings of the autumn, a Merlin and a Ring Ouzel. Visible passage was noticeably lighter than yesterday although there were still plenty of birds on the move including 50 more Siskins over the Bill. An Avocet was the pick of the waders at Ferrybridge and 25 Wigeon and 7 Teal passing the Bill constituted the best of the morning's seawatch reports.

  September 26th

Quite a bit more on the move today with plenty overhead and a marked improvement in numbers of grounded migrants. At the Bill the first few hours of the morning produced totals of visible migrants that included 2000 Meadow Pipits, 300 Linnets, 150 alba wagtails, 20 Siskins, 14 Golden Plover, 11 Lapwings, 11 Grey Wagtails, 10 Yellow Wagtails, 7 Tree Pipits and singles of Snipe, Short-eared Owl, Redpoll, Lapland Bunting and Reed Bunting. Grounded migrants there included 60 each of Wheatear and Chiffchaff, 50 Robins, 35 Stonechats, 25 Blackcaps, 5 Goldcrests, 2 each of Whinchat, Sedge Warbler, Willow Warbler and Firecrest and singles of Whitethroat and Spotted Flycatcher, whilst 12 Siskins and a Firecrest at Barleycrates Lane/Reap Lane and 15 Knot, 2 Bar-tailed Godwits and a Mediterranean Gull were the best of the sightings elsewhere.

Four Silver Y were the only immigrants in the Obs garden moth-traps this morning.

September 25th

Quality remains hard to come by at the moment and there certainly wasn't much to get excited about today. With clear skies and a stiff north-westerly wind most of what was logged was passing overhead: hirundines and Meadow Pipits were plentiful everywhere and the first decent numbers of Siskins included 50 over the Bill, 12 over Weston, 4 over Sweethill and another 11 settled at Wakeham. In was much quieter on the ground where the pick of the reports were of a Golden Plover and a Pied Flycatcher at the Bill, 2 Firecrests at Sweethill and singles of Redstart and Firecrest at Wakeham. A lone Balearic Shearwater off the Bill was the only sighting of note on the sea.

...fault bars are one of those features that are much more easily observed in the hand than in the field (and the occasional field views of well-marked examples can be mistaken for, for example, wing-bars or dark tail tips). Conventional wisdom has it that they are formed when feather growth is interrupted by a period of nutritional stress and they are often quoted as being a useful clue to ageing: well aligned fault bars as in the Blackcap's tail and wing in the top two pictures are likely to be formed when juvenile feathers are grown simultaneously in the nest, whereas poorly aligned bars restricted just to certain feather tracts are more likely to be formed during a sequential moult and are thus more typical of adults (...we won't dwell on the many possible exceptions to these scenarios save to say that caution should be exercised and fault bars are perhaps best used as a 'back-up' ageing feature!). Having mentioned Blackcap it's worth drawing attention to the differences in tail feather shape between first-years and adults: the tails shown above are both first-year tails with some next generation feathers growing after accidental feather loss.

  September 24th

The windiest day of the autumn so far but much less productive on the sea that of late with nothing of better quality than a couple of Arctic Terns passing the Bill during the morning. The only noteworthy reports from the land were of a Merlin and a Golden Plover at the Bill, a Pied Flycatcher and a Firecrest at Southwell and 7 Mallard, 2 Knot and singles of Little Stint, Curlew Sandpiper and Bar-tailed Godwit at Ferrybridge.

September 23rd

With the wind having picked up again the sea received quite a bit of attention and the onset of drizzly showers and reduced visibility from midday onwards produced a fair list of sightings including 30 Great Skuas, 20 Sooty Shearwaters, 9 Manx Shearwaters, 4 Balearic Shearwater, 4 Arctic Terns, 2 Arctic Skuas and singles of Shelduck, Teal, Wigeon and Pomarine Skua the best off the Bill. A surprise on the land was another Corncrake flushed up by chance near the Obs but otherwise the pick of the sightings at the Bill were of 4 Grey Wagtails, 4 Tree Pipits, 2 Sedge Warblers and singles of Golden Plover, Redstart, Grasshopper Warbler, Pied Flycatcher and Reed Bunting, whilst Ferrybridge chipped in with 2 Mediterranean Gulls, a Knot and an Arctic Tern. Despite the threatening-looking skies there was some passage overhead, including 750 Swallows and 350 Meadow Pipits over Ferrybridge in an hour early in the morning.

The immigrant tally in the Obs garden moth-traps this morning didn't get beyond 2 Rusty-dot Pearl and a lone Diamond-back Moth.

September 22nd

The first relatively still day since last weekend produced quite a bit of visible passage but, Wheatears and Chiffchaffs aside, not too much on the deck; sea passage dried-up completely. Overhead passage included 5000 Swallows and 1000 Meadow Pipits over Ferrybridge in an hour early in the morning and 3000 Meadow Pipits, 29 Grey Wagtails, 12 Tree Pipits, 10 Skylarks, 6 Chaffinches, 4 Reed Buntings, 3 Siskins, 2 Golden Plovers and 2 Redpolls over the Bill in the first four hours of the day. Grounded migrants included 90 Wheatears, 50 Chiffchaffs, 2 Redstarts, a Merlin, a White Wagtail and a Grasshopper Warbler at the Bill and an Arctic Tern at Ferrybridge, whilst the only sighting of note on the sea was of a Balearic Shearwater passing the Bill. 

A lone Delicate was the only immigrant in the Obs garden moth-traps this morning.

  September 21st

Early afternoon update. 

More of the same today with the sea providing nearly all the day's sightings. Watches at the Bill through the morning produced 31 Kittiwakes, 26 Sooty Shearwaters, 21 Razorbills, 14 Common Scoter, 13 Fulmars, 9 Balearic Shearwaters, 3 Guillemots and singles of Manx Shearwater, Great Skua, Arctic Skua and Arctic Tern. The only noteworthy sightings on the land were of a Yellow-legged Gull and a Firecrest at the Bill.

...many of the day's Balearics were passing extremely close; for example, five of this party of six were close enough to have disappeared from view beneath the cliff-top as they rounded the Bill. 

  September 20th

A stiff westerly wind dominated proceedings again and the majority of reports were from the sea where the most noteworthy feature was the best movement of Balearic Shearwaters since the summer. The day's seawatch totals at the Bill included 74 Balearics, 47 Kittiwakes, 28 Common Scoter, 27 Sooty Shearwaters, 27 Razorbills, 3 Arctic Skuas, 3 Guillemots and a Great Skua. The land was very much the poor relation and the only notable reports were of a Golden Plover, a Redstart and a Firecrest at the Bill and singles of Sanderling and Knot at Ferrybridge.

September 19th

The promised change in the weather duly arrived as strong west/south-westerlies set in overnight and pretty much all the interest was on the sea. After a slow start passage picked up through the morning and by tea-time totals of 250 Kittiwakes, 27 Arctic Skuas, 25 Sooty Shearwaters, 16 Common Scoter, 11 Manx Shearwaters, 5 Balearic Shearwaters, 5 Arctic Terns and 4 Great Skuas had been logged at the Bill. Precious little attention was paid to the land but odds and ends reported from the Bill included 2 Blackcaps, a Redstart and a Goldcrest.

Singles of Delicate and Silver Y were the only immigrants in the Obs garden moth-traps this morning.

September 18th

In clear and sunny conditions the day soon warmed up after a chilly start. Conditions were quite favourable for overflying migrants and there were counts of, for example, 175 Meadow Pipits over Ferrybridge and 600 Meadow Pipits, 12 Tree Pipits, 4 Sparrowhawks, a Lapland Bunting and good numbers of hirundines over the Bill in the first couple of hours of the morning before passage petered out. The pick of a pretty thin selection on the ground were 3 Redstarts, Whimbrel, a Yellow-legged Gull and a Firecrest at the Bill and 2 Mediterranean Gulls, a Sanderling, a Curlew Sandpiper and a Common Gull at Ferrybridge.

September 17th

A rather cooler and fresher day than of late but despite the change there wasn't much improvement in migrant numbers. The Bill area produced a thin spread of most of the expected mid-September species but the only double-figure counts of grounded migrants were of 35 Chiffchaffs, 25 Yellow Wagtails and 10 Willow Warblers and the only very minor highlights were 3 White Wagtails, a Golden Plover and a Grasshopper Warbler. Two each of Sanderling, Curlew Sandpiper and Mediterranean Gull were the best on offer at Ferrybridge.

  September 16th

An improvement in the quality of the day's bird-list saw the sea provide most of the highlights for the first time in many weeks. The action on the sea developed late in the afternoon as a fresh south-westerly wind set in and the Bill produced totals of 27 Common Scoter, 9 Balearic and 3 Sooty Shearwaters, 2 Great Skuas, a Mediterranean Gull and singles of Arctic, Great and Long-tailed Skua; an additional Arctic Skua passed overhead at Ferrybridge. Interest on the land was restricted to 5 White Wagtails, 2 Grasshopper Warblers, a Whimbrel, a Great Spotted Woodpecker, a Ring Ouzel, a Redstart, a Pied Flycatcher and small numbers of commoner migrants at the Bill and 2 Curlew Sandpipers, 2 Sanderling, 2 Mediterranean Gulls, a Merlin and a Little Stint at Ferrybridge. Migrants were much more plentiful overhead with totals of 1300 Meadow Pipits, 35 Yellow Wagtails, 30 Grey Wagtails and 11 Tree Pipits passing through at the Bill in the first few hours of the morning.

A single Delicate was the only immigrant of the night in the Obs garden moth-traps.

September 15th

Not much change today in yet more extremely fair conditions. One or two Ortolan Buntings were seen at the Bill early in the morning but as in previous days there were no later sightings of a settled individual; the pick of the rest of the sightings were of the autumn's first Brent Goose and Ring Ouzel (at Ferrybridge and Broadcroft Quarry respectively). Migrant totals at the Bill included 250 Meadow Pipits, 50 Yellow Wagtails, 25 Wheatears, 15 each of Willow Warbler and Chiffchaff, 11 Grey Wagtails, 7 Tree Pipits, 6 Spotted Flycatchers, 4 Blackcaps, 3 Whitethroats, 2 Golden Plovers and singles of Whinchat, Redstart, Grasshopper Warbler, Lesser Whitethroat and Goldcrest, whilst elsewhere there were 3 Mediterranean Gulls, 2 Sanderling, a Merlin and a Little Stint at Ferrybridge. The only reports from the sea were of 5 Sandwich Terns and an Arctic Skua passing through off the Bill.

A single Rusty-dot Pearl was the night's only immigrant in the Obs garden moth-traps.

  

  

 

  Chiffchaff - Portland Bill, 14th September 2007 © Martin Cade

...our little series of ageing features that we started back in late August has been hampered in the last couple of weeks not only by the lack of birds but also by the lack of adult migrants (adults are usually much too worldly-wise and wouldn't entertain stopping at a god-forsaken migration watchpoint like Portland unless it was absolutely necessary) so we've decided to highlight a few individual cases as and when they crop up . Today's Chiffchaff is a nice example of a first-year with a well-marked moult limit in the greater coverts that would be just as visible in the field as it was in the hand. Not all first-year Chiffchaffs are as obvious as this and in many the moult limit is tricky to detect in the hand, let alone the field. This moult limit is absent in adults as they undertake a complete post-breeding moult before autumn migration.

  September 14th

A repeat of yesterday without most of the scarcities - in other words rubbish! The one morsel of quality was provided by a crack of dawn Ortolan Bunting over the Obs garden; 4 White Wagtails, 2 Golden Plover and a Merlin at the Bill, another Merlin at Priory Corner and 4 Mediterranean Gulls and a Curlew Sandpiper at Ferrybridge provided the only other faint hints of quality. Common migrant numbers were still dreadful, with just five migrants trapped and ringed at the Obs (where the month's ringing total stands at a paltry 80 birds) and, hirundines and Meadow Pipits aside, just Yellow Wagtail, Grey Wagtail, Wheatear and Chiffchaff reaching double figure totals at the Bill.

Overnight mothing at the Obs has been so poor in recent days that we've got out of the habit of mentioning the daily immigrant totals; today provided just 2 Silver Y and 1 Rusty-dot Pearl.

  September 13th

Hirundines aside, there was still no upturn in common migrant numbers and it was left to a small selection of scarcer species to provide the interest today. The Bill produced most of the highlights with a Pomarine Skua and a Little Gull past on the sea, a Hobby and a Spotted Redshank passing overhead and singles of Merlin, Turtle Dove, White Wagtail, Grasshopper Warbler and Firecrest scattered around on the land; elsewhere another Hobby passed over at the Grove and 2 Knot, a Black-tailed Godwit and a Curlew Sandpiper were at Ferrybridge. Hirundines were very plentiful but otherwise the selection of commoner migrants logged barely merits a mention beyond reporting that numbers were much lower than might be expected in mid-September.

  September 12th

In yet more fair weather grounded migrants remained as thinly spread as in recent days (there were for example just a dozen Wheatears at the Bill and only three new migrants were trapped and ringed in the Obs garden) but there was a fair bit of passage overhead, with 700 Meadow Pipits, 70 Yellow Wagtails, 16 Grey Wagtails, 8 Snipe, 6 Tree Pipits, 4 White Wagtails, a Little Egret, a Green Sandpiper and a Dunlin passing over at the Bill during the first few hours of the morning. The best of the grounded migrants were 2 Ortolan Buntings that dropped in at Watery Lane during the morning; the Bill couldn't muster anything of better quality than 4 Grasshopper Warblers. Seawatching at the Bill produced 2 Arctic Skuas and a Balearic Shearwater, whilst 2 Sanderling and a Mediterranean Gull the the best on offer at Ferrybridge.

September 11th

A shift in the wind direction back to north-easterly was welcome but grounded migrants were still in short supply after a very clear night. The only oddities reported were an Osprey that flew south along the West Cliffs early in the afternoon and a Ruff that flew past the Bill. At the Bill most of what movement there was involved fly-overs and even many of the warblers and flycatchers were not stopping as they passed through the Obs garden; totals for the morning there included 250 Meadow Pipits, 40 each of Yellow Wagtail and Wheatear, 20 each of Grey Wagtail and Chiffchaff, 15 Willow Warblers, 10 each of Tree Pipit and White Wagtail, 8 Spotted Flycatchers and smaller numbers of a fair range of other expected species along with a single early-ish Reed Bunting. A trickle of passage off the Bill included 6 Arctic Skuas passing through. The only other reports were from Ferrybridge where there were 3 Sanderling and 2 Knot amongst the commoner waders.

September 10th

A brisker wind from the dreaded north-west today and the migrant tally was particularly grim. In what has become an almost daily ritual an Ortolan Bunting put in a subliminal appearance (today's individual was settled briefly at Culverwell before flying off north) but the only other oddities reported were a couple of single Little Egrets that flew over the Bill and a Yellow-legged Gull that was settled on East Cliffs. For the first time this autumn Chiffchaffs outnumbered Willow Warblers (although with the former numbering just 15 at the Bill phylloscs were hardly conspicuous); the only other species to reach double figure totals at the Bill were Yellow Wagtail and Wheatear. Seawatching at the Bill produced 3 Bar-tailed Godwits and singles of Balearic Shearwater and Arctic Skua.

A Delicate and the year's first Old Lady were minor highlights in the Obs garden moth-traps this morning; 4 Rusty-dot Pearl and 4 Silver Y were the only other immigrants in the traps.

  September 9th

A cloudier start to the morning promised a few more grounded migrants but in the event failed to deliver. The one notable highlight of the day was a Corncrake that was flushed by chance near the Obs but promptly dived for cover and was never seen again; one or more Ortolan Buntings were also seen again at the Bill although as in recent days none of the sightings were of an 'easy' settled individual. The common migrant tally was not dissimilar to yesterday's, with 40 Yellow Wagtails, 40 Willow Warblers, 14 Tree Pipits, 20 Wheatears,15 Chiffchaffs and 10 Whitethroats making up the bulk of the numbers at the Bill; odds and ends of better quality there included 2 Grasshopper Warblers, 2 Pied Flycatchers, a Yellow-legged Gull and a White Wagtail. The list from Ferrybridge included 4 Black-tailed Godwits, 4 Sanderling, 2 Knot and a Curlew Sandpiper.

We've been lazy in recent days and hardly mentioned butterflies and day-flying moths. A Brimstone was a minor highlight today in the Obs garden (this species is always scarce on the island and there are very few records for the autumn 'pre-hibernation' flight period). Two 'near-misses' in recent weeks have been a presumed Long-tailed Blue seen very briefly at the Bill during the August Bank Holiday weekend and what could only have been a Swallowtail/Scarce Swallowtail seen equally briefly by a day-visitor to the Bill last week. Among the more routine immigrants Red Admirals have been fairly plentiful, Painted Ladys have begun to appear in some numbers only in the last ten days or so and Hummingbird Hawk-moths have been extremely few and far between. 

September 8th

Not even a hint of a change in the weather but - perhaps as we are now entering the New Moon period? - slightly more in the way of grounded migrants today. The list from the Bill area included a fly-over Ortolan Bunting as the highlight, along with 60 Yellow Wagtails, 50 Willow Warblers, 14 Tree Pipits, 10 each of Wheatear and Spotted Flycatcher, 8 Grey Wagtails, 7 each of White Wagtail and Blackcap, 6 Whitethroats, 5 each of Whinchat and Lesser Whitethroat, 4 each of Sedge Warbler and Pied Flycatcher and ones or twos of Redshank, Snipe, Swift, Redstart, Reed Warbler, Garden Warbler, Goldcrest and Siskin; Meadow Pipits were also beginning to get moving overhead and as expected there were plenty of hirundines on the move. The only other reports came from Ferrybridge where 196 Dunlin, 38 Oystercatchers, 7 Curlew, 4 Mute Swans, 3 Curlew Sandpipers, 3 Sanderling, 3 Mediterranean Gulls and a Snipe were the pick of the early morning sightings.

Four Rusty-dot Pearl, 3 Silver Y and an Evergestis extimalis were the only immigrants/wanderers in the Obs garden moth-traps this morning.

  September 7th

Does prolonged fine weather as early in the autumn as early September qualify as an Indian summer? Either way the current warmth and sunshine look set to remain and aren't doing the birders any favours as grounded migrants are far from plentiful. Today's haul at the Bill included 70 Yellow Wagtail, 25 Wheatear, 16 Tree Pipit and 10 Willow Warbler; among the smaller numbers of other species there were 3 White Wagtails, 2 Spotted Flycatchers, a Merlin, a Redstart and a Lesser Whitethroat on the land and the first Diver sp of the autumn passing through on the sea. Ferrybridge continues to be well worth a look, with a Purple Sandpiper providing the highlight there today; 7 Sanderling, 2 Curlew Sandpipers, a Bar-tailed Godwit, a Mediterranean Gull and a Kingfisher were the pick of the rest of the sightings there.

Six Rusty-dot Pearl, 4 Silver Y, a Rush Veneer and an Oak Hook-tip were the only immigrants/wanderers in the Obs garden moth-traps this morning.

  

  

 

   Curlew Sandpipers and Mediterranean Gull - Ferrybridge, 6th September 2007 © Pete Saunders

  September 6th

Clear blue skies and hot sunshine today - ideal conditions for migrants to pass straight overhead without stopping. The Wryneck showed briefly again at the Privet Hedge and a Great Spotted Woodpecker put in an appearance at Barleycrates Lane but in the common migrant line only passing hirundines were well represented. Yellow Wagtail, Tree Pipit, Wheatear and Willow Warbler all just managed double figures at the Bill where the only slightly scarcer species logged were 4 White Wagtails, 3 Lesser Whitethroats, 2 Grey Herons, a Snipe and a Whimbrel. Ferrybridge fared a little better with 4 Sanderling, 2 Curlew Sandpipers, a Knot, a Bar-tailed Godwit and a Mediterranean Gull the best on offer.

There was precious little change in the Obs garden moth-traps with singles of Rush Veneer, Rusty-dot Pearl, Nephopterix angustella, Convolvulus Hawk-moth and Silver Y the only immigrants/wanderers recorded.

  September 5th

Unfortunately it was back to square one today with passage reduced to a mere trickle again. An Ortolan Bunting flew over Top Fields in the morning and a Wryneck showed briefly at the Privet Hedge but among the commoner migrants at the Bill the only double figure counts were of 50 Yellow Wagtails, 23 Tree Pipits and 16 Grey Wagtails; less regular species there included singles of Snipe, Golden Plover and Kingfisher. Seawatching at the Bill produced singles of Balearic Shearwater and Arctic Skua.

Immigrants/wanderers in the Obs garden moth-traps this morning included 4 Silver Y, 3 Convolvulus Hawk-moth, 2 Rusty-dot Pearl and a Dark Spectacle.

  September 4th

A distinct improvement today with quite a few common migrants on the move and some quality in the form of at least 2 Ortolan Buntings (2 together over the Obs, a couple of fly-over singles over Top Fields and 1 settled near the Windmills at Easton) and a Wryneck (in Top Fields so maybe different to yesterday's individual). The migrant tally for the Bill area included 75 Yellow Wagtails, 65 Wheatears, 25 Tree Pipits, 25 Willow Warblers, 20 Whinchats, 13 Grey Wagtails, 10 Whitethroats, 5 Goldcrests, 4 White Wagtails and ones or twos of Grey Heron, Ringed Plover, Turtle Dove, Grasshopper Warbler, Sedge Warbler, Reed Warbler, Chiffchaff and Spotted Flycatcher, whilst elsewhere there were 25 Wheatears and 20 Whinchats scattered around the centre of the island and 120 Ringed Plover, 50 Dunlin, 18 Knot, 3 Sanderling and a Shelduck at Ferrybridge.

Still not much to report from the Obs garden moth-traps that attracted by way of immigrants just 6 Silver Y, 3 Rusty-dot Pearl and a Southern Wainscot

September 3rd

The one high point today was the (re-)discovery at the Privet Hedge of what was presumably Saturday's Wryneck that had escaped notice yesterday. On the common migrant front it was a case of hoping that the day represented the low point of autumn as numbers couldn't really get any worse (in ideal mist-netting conditions not a single bird was ringed in the the Obs garden all morning). The pick of what was around included 50 Yellow Wagtails, 15 Wheatears, 10 Willow Warblers, 8 Turnstones, 7 Grey Wagtails, 5 Whinchats, a Grey Heron, a Little Egret, a Ringed Plover, a Yellow-legged Gull and a Pied Flycatcher at the Bill and singles of Merlin, Knot and Sanderling at Ferrybridge.

Singles of Rusty-dot Pearl, Convolvulus Hawk-moth, Dark Spectacle, Silver Y and Red Admiral butterfly provided the only immigrant/wanderer interest in the Obs garden moth-traps this morning.

September 2nd

It didn't get any better today with migrant numbers dropping back to a very low level for this stage of the autumn. All that was on offer at the Bill were 40 Yellow Wagtails, 9 Wheatears, 7 Grey Wagtails, 5 White Wagtails, 5 Willow Warblers, 4 Tree Pipits, 4 Whinchats, 3 Whitethroats, a Whimbrel, a Lesser Whitethroat and a Chiffchaff, whilst elsewhere the best were singles of Merlin and Siskin at Barelycrates Lane and 200 Ringed Plover, 40 Dunlin, a Merlin and a Sanderling at Ferrybridge. With the wind still well round in the north-west sea interest was limited to 18 Common Scoter, a Balearic Shearwater and a Razorbill passing through off the Bill.

Two Rusty-dot Pearl, a Convolvulus Hawk-moth and a Southern Wainscot were the only immigrants/wanderers attracted to the Obs garden moth-traps overnight.

  September 1st

A Wryneck that showed up above Culverwell during the afternoon provided a welcome minor highlight after a relatively barren few days. Common migrant numbers improved a little at the Bill where there were 60 Yellow Wagtails, 20 Wheatears, 20 Willow Warblers, 10 Whinchats, 8 Tree Pipits, 6 Lesser Whitethroats, 4 White Wagtails, 3 Grey Wagtails, 3 Blackcaps and odd ones and twos of several of the other expected early September species; singles of Hobby and Yellow-legged Gull provided the only other scarcity interest there.

The Obs garden moth-traps remained very quiet, with 3 Rusty-dot Pearl, a Convolvulus Hawk-moth and a Vapourer the only immigrants/wanderers recorded.

August 2007

August 31st

With a subtle shift in wind direction from north-east to north-west as the week has gone on so passage has all but ground to a halt and there was certainly precious little to entertain visitors today. Odds and ends at the Bill - where Yellow Wagtail was the only one of the commoner migrants to return a double figure total - included 3 Tree Pipits, 2 each of Whinchat, Garden Warbler and Lesser Whitethroat and singles of Yellow-legged Gull, White Wagtail, Reed Warbler and Spotted Flycatcher; seawatching there produced 3 Balearic Shearwaters, 2 Great Skuas and an Arctic Skua.

Overnight moth-trapping at the Obs was barely worth reporting on: 11 Rusty-dot Pearl, 4 Silver Y and a Diamond-back Moth were the only immigrants caught.

August 30th

Just slim pickings today after another very clear night. The Bill's tally of common migrants certainly wasn't interesting enough to report in full but did include 60 Yellow Wagtails, 10 Tree Pipits, 3 Lesser Whitethroats, 2 Grey Wagtails, 2 White Wagtails and singles of Hobby, Redshank, Common Sandpiper, Yellow-legged Gull, Redstart, Grasshopper Warbler, Pied Flycatcher and Spotted Flycatcher. With what breeze there was still firmly offshore there wasn't much attention paid to the sea but 2 Balearic Shearwaters did pass through off the Bill.

Overnight mothing remained uneventful: the only immigrants trapped at the Obs were 9 Rusty-dot Pearl, 7 Silver Y, 2 Diamond-back Moths and a Convolvulus Hawk-moth.

August 29th

With the exception of an Ortolan Bunting that put in a brief appearance at Barleycrates Lane early in the afternoon there wasn't too much to report today. Migrants on the land at the Bill included 50 Yellow Wagtails, 30 Tree Pipits, 25 Wheatears, 11 Whinchats, 5 Grey Wagtails, 3 Ringed Plovers, 3 Garden Warblers, 2 Grey Herons, 2 Lesser Whitethroats and singles of Yellow-legged Gull, Sedge Warbler, Grasshopper Warbler and Spotted Flycatcher; a lone Mediterranean Gull was the only sighting of note on the sea at the Bill.

Overnight mothing at the Obs was as uneventful as the birding with 16 Rusty-dot Pearl, 6 Silver Y and a Dark Spectacle the only immigrants recorded.

  

  

 

 

 

 

       

   Garden Warbler - Portland Bill, August 2007 © Martin Cade 

...continuing our ageing theme from a couple of days ago with a look at Garden Warbler, a species in which the ages classes are quite tricky to tell apart. The majority of adults don't moult until they reach winter quarters but their plumage never seems to be as worn in autumn as might be expected. First years possess uniformly fresh plumage which is a little glossier, warmer and browner than the worn, colder and greyer plumage of adults; in particular the wing and tail feathers of adults are slightly ragged and faded, although even in the hand this often subtle difference can be easily missed. Note that the tips of the adult tail feathers, although worn, are clearly more rounded than the pointed first year feathers.

  August 28th

With us now in the full moon period there wasn't much anticipation of a good fall of migrants and even a reasonable cloud cover at dawn didn't make much difference today. Among the light scatter of birds at the Bill there were 100 Yellow Wagtails, 10 Whinchats, 7 Tree Pipits, 4 Sedge Warblers, 3 Snipe, 3 Grey Wagtails, 2 Lesser Whitethroats, 2 Spotted Flycatchers, a Grey Heron, a Greenshank, a Common Sandpiper and a Grasshopper Warbler. Waders are often well represented in the full moon period and Ferrybridge continued to provide plenty of variety including 6 Sanderling and singles of Grey Plover, Knot, Curlew Sandpiper and Mediterranean Gull.

Overnight mothing wasn't too interesting: 5 Rusty-dot Pearl, 3 Diamond-back Moth, 3 Silver Y, a Pearly Underwing and a Dark Spectacle were caught at the Obs and a Southern Wainscot was the best at Southwell.

  August 27th

It was a case of quality rather than quantity today as common migrants were distinctly thinner on the ground but four Ortolan Buntings and an Osprey put in an appearance. A lone and for the most part rather elusive Ortolan roamed around the Helen's Fields area of Top Fields at the Bill and a party of three flew north over Ferrybridge (click here for a brief recording of the Helen's Fields bird calling in flight); the Osprey flew south over Southwell and the Bill during the afternoon. Among the migrants at the Bill there were 20 Whinchats, 10 Tree Pipits, 6 Spotted Flycatchers, 4 Lesser Whitethroats, 2 Grey Herons and a Grasshopper Warbler together with a light sprinkle of commoner species. Ferrybridge provided plenty of interest including 29 Redshank, 3 Grey Plover, 2 Knot and singles of Curlew Sandpiper, Little Stint, Black-tailed Godwit and Mediterranean Gull, whilst seawatching at the Bill produced 29 Redshank (presumably the Ferrybridge flock), 3 Balearic Shearwaters and a Great Skua.

  

  

 

 

 

 

       

       

   Bedstraw Hawk-moth and Redstarts - Portland Bill, 26th August 2007 © Martin Cade 

...common migrants have been plentiful in recent days and there have been good opportunities to compare adult and first year plumages of several species. In male Redstart the age classes are relatively easy to separate: the adults always look 'smarter' and have, for example, blue edged greater coverts (buff edged in first years) and broad, rounded tail feathers (narrower and pointed in first years). In the experience of this writer the age classes in females are much trickier to separate, even in the hand.

  August 26th

Plenty more of the same today although not quite the large fall that looked on the cards after a veil of cloud had appeared overhead before dawn. Willow Warblers dominated at the Bill (150 logged) but among the wide selection of other species there there were, for example, 25 Tree Pipits, 16 Whinchats, 7 Pied Flycatchers, 6 Redstarts, 2 Grasshopper Warblers and the first Goldcrest and Siskin of the autumn. Most other sites visited provided a similar array of migrants and an escaped Patagonian Conure provided additional interest at Weston.

The pick of the night's captures in the Obs garden moth-traps was the second Bedstraw Hawk-moth of the autumn.

Fuller details of the rest of the sightings to follow later.

  

  

  

   Scar Bank Gem and Common Gull - Portland Bill, 25th August 2007 © Martin Cade 

...the Common Gull was one of the more peculiar sightings of the day; it spent much of the morning (and indeed had been present in the same spot yesterday) wandering around amongst the parked cars and holidaymakers in the field beside the Obs Quarry. Common Gulls are very infrequent visitors to the island between May and October and are hardly ever seen settled on the land at the Bill at any time.

  August 25th

For once the highlight of the day came from the moth-traps: the second Portland specimen (ca15th British record) of Scar Bank Gem was caught overnight at the Obs.

On the bird front the overall tally of species was rather similar to the last few days although numbers were quite a bit lower with less having dropped in after a virtually cloudless night. Nothing of great note was found in the Bill area where there were, for example, 75 Yellow Wagtails, 30 Whinchats, 30 Whitethroats, 12 Pied Flycatchers, 7 White Wagtails, 7 Lesser Whitethroats, a Turtle Dove, a Grasshopper Warbler and a Dartford Warbler amongst plenty of commoner migrants. Two Great Skuas passed through on the sea at the Bill and 2 Grey Plover, a Merlin, a Little Stint and a Mediterranean Gull were the pick of the bunch at Ferrybridge.

  August 24th

Another nice arrival of common migrants today in increasingly cloudy and muggy conditions. The centre and south of the island was well covered and returned totals that included 150 Wheatears, 100 Yellow Wagtails, 100 Willow Warblers, 55 Tree Pipits, 50 Whitethroats, 50 Spotted Flycatchers, 35 Whinchats, 20 Sedge Warblers, 20 Garden Warblers, 15 Pied Flycatchers, 8 Lesser Whitethroats, 20 Redstarts, 2 Greenshank, 2 Grasshopper Warblers, 2 Reed Warblers, a Purple Sandpiper, a Merlin and a Nightingale. Ferrybridge produced 2 Grey Plover, a Curlew Sandpiper and singles of Mediterranean Gull and Common Gull, whilst odds and ends passing on the sea included a couple of Great Skuas and a Manx Shearwater off the Bill.

A Great Dart was a notable highlight in the Obs garden moth-traps; 6 Rusty-dot Pearl, 5 Silver Y, a Rush Veneer and a White-speck were the only other immigrants recorded.

  August 23rd

The stiff north-easterly wind of recent days remained a feature and there was plenty more visible passage and a fair scatter of grounded migrants; at the Obs the total of 40 new birds trapped and ringed by the time of writing these notes represented the highest day total of new arrivals so far this autumn (...and provided a good indication of just how poor the early autumn has been for grounded warblers). Given the conditions it wasn't too much of a surprise that a Wryneck showed up in Top Fields at the Bill; much more unexpected at this time of year was a Serin seen briefly near the Privet Hedge at the Bill. Among the common migrants there was a strong passage of hirundines overhead and the Bill area produced counts of other species that included 200 Wheatears, 50 Tree Pipits, 50 Willow Warblers, 25 Whitethroats, 20 Yellow Wagtails, 20 Spotted Flycatchers, 10 Whinchats, 7 Sedge Warblers, 7 Garden Warblers, 5 Lesser Whitethroats, 4 Redstarts, 2 Greenshank, 2 Whimbrel, a Lapwing, a Snipe and a Purple Sandpiper; a Hobby at the Verne was the pick of the sightings elsewhere. The only reports from the sea were of an Arctic Tern and an Arctic Skua passing the Bill, whilst waders at Ferrybridge included 2 Grey Plover and the first Curlew Sandpiper of the autumn.

The brisk wind again spoilt overnight moth-trapping although immigrant totals at the Obs did creep up a little: 15 Rusty-dot Pearl, 5 Rush Veneer, 5 Silver Y and a Convolvulus Hawk-moth.

August 22nd

Lots more movement today, notably involving Tree Pipits and raptors. The latter included a Honey Buzzard flying north over the centre and north of the island during the afternoon, a Marsh Harrier over Tout Quarry in the morning and the first Merlin of the autumn at the Bill. Around 100 Tree Pipits passed over at the Bill where 10 Yellow Wagtails and 10 Ravens also passed through; on the ground there were 100 Wheatears, 50 Willow Warblers, 11 Spotted Flycatchers, 6 Common Sandpipers, 4 Sedge Warblers, 3 Garden Warblers, 2 Grasshopper Warblers, 2 Lesser Whitethroats, a Redshank and a Yellow-legged Gull at the Bill, 10 Spotted and 4 Pied Flycatchers around the centre of the island and 2 Avocets and a Greenshank at Ferrybridge. Seawatching at the Bill produced 4 Great Skuas, 3 Arctic Skuas and 2 Balearic Shearwaters, whilst a Black Tern was in Portland Harbour.

Despite a brisk wind overnight the Obs garden moth-traps were quite busy although the only immigrants trapped were 6 Silver Y, a Rusty-dot Pearl and a Convolvulus Hawk-moth.

  August 21st

Birding was quite hard work for much of the day in an unexpectedly strong north-east wind. An overflying Marsh Harrier at the Bill and Southwell was the best of the oddities although a decent movement of Tree Pipits at the Bill and an obliging Greenshank at Ferrybridge provided further interest. The migrant tally at the Bill included 50 Tree Pipits, 30 Wheatears, 20 Willow Warblers, 3 Dunlin, 3 Whinchats, 3 Sedge Warblers and singles of Little Egret, Ringed Plover, Yellow Wagtail, Grey Wagtail and Grasshopper Warbler, whilst Ferrybridge chipped in with 170 Ringed Plover, 30 Dunlin, 14 Wheatears and 3 Sanderling

  August 20th

With yesterday's stiff wind having dropped right away overnight there was much more to see on the land early in the morning before the arrival of yet more rain spoilt proceedings. The small flurry of new arrivals at the Bill included 70 Willow Warblers, 20 Wheatears, 15 Tree Pipits, 11 Sedge Warblers, 10 Whitethroats, 2 Whinchats, 2 Garden Warblers and singles of Grey Heron, Snipe, Redstart, Grasshopper Warbler, Reed Warbler and Blackcap; elsewhere there was a Yellow-legged Gull at Barleycrates Lane. Some light passage on the sea at the Bill included 22 commic terns, 13 Manx and a Balearic Shearwater, 12 Common Scoter, a Great Skua and a Sandwich Tern passing by.

A lone Rusty-dot Pearl was the only immigrant attracted to the Obs garden moth-traps overnight.

August 19th

Fresh north-westerlies today - one of the local birder's least favourite conditions! On the land passage remained at a virtual standstill with nothing much more than a dozen Wheatears, 4 Willow Warblers, 2 Spotted Flycatchers and singles of Ringed Plover, a Whimbrel, Whinchat and Sedge Warbler at the Bill and 150 Ringed Plovers, 30 Dunlin, 4 Knot and 3 Sanderling at Ferrybridge. The offshore wind did the seawatchers no favours and just 12 commic terns, 8 Manx Shearwaters, 8 Common Scoter and singles of Arctic Skua, Great Skua, Sandwich Tern and Arctic Tern were logged passing through off the Bill.

Overnight mothing was no more productive and 4 Silver Y, a Rush Veneer and a Pearly Underwing were the only immigrants caught in the Obs garden traps.

Late news for yesterday: further late afternoon/evening sightings at the Bill included at least two more Sooty Shearwaters and reports of a Cory's Shearwater (and another probable Cory's) passing through on the sea.

August 18th

Another seawatching day in windy and often quite wet conditions. Birds were hardly streaming by but there was a little more on the move than earlier in the week, with the Bill returning totals that included 29 commic terns, 14 Manx, 6 Balearic and 5 Sooty Shearwaters, 14 Common Scoter, 5 Arctic Skuas, 3 Redshank, 2 Razorbills and a Yellow-legged Gull. Odds and ends on the land included 15 Wheatears, a Tree Pipit and a Whinchat at the Bill.

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

  August 17th

Rather uneventful on land and sea. The light scatter of common migrants at the Bill included 30 Wheatears, 25 Willow Warblers, 8 Tree Pipits, 6 Redshank, 2 Sedge Warblers, 2 Reed Warblers and a Ringed Plover on or overhead on the land and 4 commic terns and a Manx Shearwater passing through on the sea, whilst at Ferrybridge there were 170 Ringed Plover, 24 Dunlin, 3 Sanderling, a Knot and a Mediterranean Gull.

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

August 16th

A nicer day today, albeit still on the windy side, saw more reports from the land. The pick of the bunch were a couple of Yellow-legged Gulls at the Bill and a fly-over Wood Sandpiper at Weston whilst common migrant totals at the Bill included 60 Wheatears, 35 Willow Warblers, 11 Tree Pipits, 2 Ringed Plover, 2 Sedge Warblers and singles of Reed Warbler and Lesser Whitethroat. The sea was actually a little more productive in a brisk north-westerly today than it had been in strong south-westerlies during the last couple of days, with 19 Manx Shearwaters, 18 commic terns, 4 Balearic Shearwaters, 4 Common Scoter, 2 Great Skuas, 2 Sandwich Terns, an Arctic Tern and a tardy auk sp passing through off the Bill.

Overnight moth-trapping produced just a handful of immigrants/wanderers: 4 Silver Y, 2 Rusty-dot Pearl, a Rush Veneer and a Small Rufous; Garden Dart was new for the year.

  August 15th

Autumn seawatching at the Bill in rough weather is invariably a dead loss and today proved to be no exception: no Little Shearwaters, no large shearwaters, no Audouin's Gulls....in fact not a lot of anything. The few things that were logged passing through included 7 Ringed Plover, 3 Manx Shearwaters, 3 Great Skuas, 2 Arctic Skuas, 2 Sandwich Terns, a Balearic Shearwater, a Sooty Shearwater, a Whimbrel and a Common Tern; the only reports from the land were of a Yellow-legged Gull and several Wheatears and Willow Warblers. Elsewhere there were 4 Common Terns, 3 Sanderling, 2 Bar-tailed Godwits, 2 Kittiwakes, 2 Arctic Terns and a Little Tern at Ferrybridge.

August 14th

Seawatching was the order of the day after a southerly gale and heavy rain had swept in overnight. The main feature at the Bill was an extremely heavy passage of Gannets with sample counts indicated that in excess of 5000 flew east between dawn and mid-afternoon (the previous highest day total there was 2500 on 5th October 1988); unfortunately there was remarkably little else on the move and the only other worthwhile sightings were of 16 Balearic Shearwaters, 2 each of Sanderling, Knot and Arctic Skua and singles of Dunlin, Whimbrel, Great Skua and Common Tern. The only other reports were of single Common Sandpipers at the Bill and Ferrybridge, a Yellow-legged Gull settled at the Bill and 2 Sanderling at Ferrybridge.

....the Fastnet Race fleet passed the Bill late today; most steered well clear of the tide race a mile offshore but a few came so close along the East Cliffs that they were disappearing from view behind the trees at the bottom of the Obs garden before they jostled for position as they rounded the Bill.

  August 13th

Another very limited list of sightings to report today, with all the news coming from the Bill where there were 20 Willow Warblers, 3 Wheatears, 2 Sedge Warblers, a Ringed Plover and a Reed Warbler on the land, 3 Balearic Shearwaters lingering offshore and 2 Manx Shearwaters, a Sooty Shearwater, a Great Skua and a Sandwich Tern passing through on the sea.

A particularly miserable overnight haul of moths in the Obs garden traps included by way of immigrants just 2 each of Diamond-back Moth and Rush Veneer and singles of Rusty-dot Pearl and Silver Y.

  

  

  

   

   Little Stints, Gold Spot and Beautiful Gothic - Ferrybridge and Portland Bill, 12th August 2007 © Pete Saunders (stints) and Martin Cade (moths)

  August 12th

A marked change in the weather which saw cloud cover and even the odd light shower arrive around dawn - decent fall conditions you'd have thought - did nothing to improve the general migrant situation and it was quieter than for some while. Three Little Stints were new arrivals at Ferrybridge but the land was remarkable quiet at the Bill where 12 Wheatears constituted the only even faintly noteworthy count of commoner migrants. Seawatching at the Bill produced 623 Gannets, 2 Common Scoter, a Balearic Shearwater, a Garganey and a Great Skua.

The pick of a dire night's mothing at the Obs were 6 Silver Y, a Rusty-dot Pearl and a Gold Spot along with the first records for the year of Flounced Rustic and Beautiful Gothic.

Late news for yesterday: a total of 469 spikes of Autumn Lady's Tresses were counted along the East Cliffs at the Bill.

August 11th

Another fine almost cloudless day - once again not the sort of conditions to expect much of a fall of migrants. At the Bill most of the expected commoner species were represented in small numbers with the pick of the better quality being 3 Yellow-legged Gulls, 2 Lesser Whitethroats, a Grasshopper Warbler and fly-over singles of Wood Sandpiper and Greenshank; the sea chipped in with 5 Balearic and 2 Manx Shearwaters, a Great Skua and a Black Tern.

Two Evergestis extimalis were the best of the immigrants caught overnight in the Obs garden moth-traps; 5 Rusty-dot Pearl, 4 Silver Y, 2 Rush Veneer and an Oak Nycteoline were the only other captures worth mentioning.

  

    

   

   A Wood Warbler comes under close scrutiny - Portland Bill, 10th August 2007 © Martin Cade

  August 10th

Hirundines aside the only one of the commoner migrants to manage a double-figure total at the Bill was Willow Warbler of which there were around 40; a lone Wood Warbler trapped at the Obs provided some quality but by and large there was little reward for the fieldworkers this morning. Odds and ends passing by on the sea at the Bill included 17 commic terns and 10 Common Scoter

Despite very clear night skies the Obs garden moth-traps have been quite busy this week although immigrants and wanderers remain pretty thin on the ground; this morning's tally included 12 Silver Y, 3 Rusty-dot Pearl, 2 Rush Veneer, a Dark Sword Grass, a Slender Brindle, the second Porter's Rustic of the week and a Red Admiral butterfly.

August 9th

Once again not as much about as might be hoped for in mid-August but the continuing very fair weather is hardly suitable for dropping migrants in any quantity. Wheatears and Willow Warblers (50ish of both) accounted for the bulk of the migrants at the Bill where the single figure totals of other species included just a lingering Yellow-legged Gull and a fly-over Great Spotted Woodpecker by way of any quality. The sea was just as dull with a lone Manx Shearwater providing the most minor of highlights.

The immigrant tally in the Obs garden moth-traps included 11 Silver Y, 3 Diamond-back Moth, 2 Rush Veneer, 2 Dark Sword Grass, a Rusty-dot Pearl and 2 Red Admiral butterflies; Canary-shouldered Thorn and an early Lunar Underwing were year-ticks.

August 8th

Another fair selection of migrants today with the Bill area producing totals of 60 each of Wheatear and Willow Warbler, 10 Whitethroats, 6 Sedge Warblers, 5 Garden Warblers, 3 each of Grey Heron and Tree Pipit, 2 Reed Warblers and singles of Whimbrel, Kingfisher, Whinchat, Dartford Warbler, Spotted Flycatcher and Pied Flycatcher along with a steady trickle of Swifts and hirundines overhead. In a stiff offshore breeze not much attention was paid to the sea and the only sightings of note at the Bill were of 3 Manx Shearwaters, a Ringed Plover and a Mediterranean Gull passing by. Elsewhere there were 41 Dunlin and 7 Sanderling at Ferrybridge.

The cool northerly hardly helped overnight moth-trapping and the only immigrants/wanderers trapped at the Obs were 12 Silver Y, 2 Rusty-dot Pearl and singles of  Convolvulus Hawk-moth, Dark Sword Grass and Crescent.

Late news for Monday 6th: a presumed Black Stork (a naked eye sighting but well described by the observer) was seen flying north-west over Easton during the morning.

  

    

   Porter's Rustic - Portland Bill, 7th August 2007 © Martin Cade

  August 7th

A little more variety to report today but overall it remained relatively quiet. Migrants grounded or passing over at the Bill this morning included 50 Willow Warblers, 15 Wheatears, 14 Tree Pipits, 10 Sedge Warblers, 2 Grey Herons and singles of Yellow Wagtail, Redstart, Whinchat, Grasshopper Warbler, Reed Warbler, Dartford Warbler and Garden Warbler; the sea came up with nothing more than 5 Common Scoter and a single Sanderling.

The Obs garden moth-traps were slightly busier than of late with 2 Convolvulus Hawk-moths and a Porter's Rustic providing some quality amongst the catch; a single Bulrush Wainscot was an unexpected wanderer from elsewhere whilst 11 Silver Y, 6 Rusty-dot Pearl, 2 Dark Sword Grass and a Diamond-back Moth were the more routine immigrants logged.

  August 6th

The promised change in the weather didn't amount to much more than a few spots of rain overnight and a slightly fresher feel to an otherwise sunny day and certainly wasn't enough to drop a substantial arrival of migrants. Willow Warblers increased to 50 or more in the Bill area but the only other reports from there were of 12 Wheatears, 5 Sedge Warblers and 2 Garden Warblers on the land, a few departing hirundines overhead and 3 Common Scoter passing on the sea. Elsewhere there was a Grey Heron over Fortuneswell and 94 Ringed Plover, 32 Dunlin, 15 Common Terns, 4 Sanderling and the summering Red-breasted Merganser at Ferrybridge.

The fourth Portland record of Dark Spinach provided the overnight highlight in the Obs garden moth-traps; 9 Silver Y, 5 Rusty-dot Pearl and singles of Diamond-back Moth, Palpita vutrealis and Dark Sword Grass were the only recognised immigrants caught and Saltern Ear was a year-tick.

....the Large Tortoiseshell was one of the four reported to have been seen on the island in early July. We have recently received further details of this sighting and in fact it refers to just one individual that was seen at Tout Quarry during the weekend of 7th/8th July.

  August 5th

Still very quiet in fine and increasingly warm conditions. The migrant tally at the Bill included 200 Swifts, 17 Wheatears and 10 Willow Warblers along with low single figure totals of a handful of the other expected early August species; seawatching there produced 400 Gannets, 10 Manx Shearwaters, 8 Common Scoter and a single Balearic Shearwater. The only other reports were of 84 Ringed Plovers, 15 Dunlin, 2 Sanderling and a Red-breasted Merganser at Ferrybridge.

Mothing seems to be going from bad to worse: 6 Rusty-dot Pearl and 3 Silver Y were the only immigrants caught overnight in the Obs garden traps; Wormwood was a year-tick.

  August 4th

Weekend visitors had a relatively lean time of it today with little more than routine sightings everywhere. Migrants at the Bill included 30 Willow Warblers, 3 Wheatears, 2 Garden Warblers, a Redstart and a Whinchat on the land, a trickle of Swifts and hirundines overhead and 10 Common Scoter, 5 Balearic Shearwaters, 5 Great Skuas and an Arctic Skua on the sea. Pick of the sightings elsewhere included 113 Ringed Plovers, 27 Dunlin, a Red-breasted Merganser and a Sanderling at Farrybridge, a Yellow-legged Gull and a Whinchat at Barleycrates Lane and the Great Spotted Woodpecker again at Southwell. 

Another Convolvulus Hawk-moth was the pick of the overnight captures in the Obs garden moth-traps that otherwise didn't come with more than 9 Silver Y, 4 Rusty-dot Pearl and a Diamond-back Moth by way of immigrants. 

  

 

     Swift - Portland Bill, August 3rd 2007 © Martin Cade

  August 3rd

Just steady and relatively uneventful return passage to report today with the crystal-clear night sky ensuring that most migrants carried on overhead without stopping. The Bill area produced totals that included 200 Swifts, 100 Swallows, 100 Sand Martins, 25 Willow Warblers, 15 Wheatears, 4 Whimbrel, 4 Whinchats, 2 Sedge Warblers and singles of Ringed Plover, Greenshank, Green Sandpiper, Yellow-legged Gull and Yellow Wagtail; 12 commic terns, 4 Common Scoter and 2 Balearic Shearwaters also passed by on the sea. The only report from elsewhere was of a Great Spotted Woodpecker at Southwell.

It was very quiet overnight in the Obs garden moth-traps, with 12 Silver Y, 6 Rusty-dot Pearl and 3 Dark Sword Grass the only immigrants recorded.

  August 2nd

The arrival of a party of 4 Kentish Plovers at Ferrybridge provided a real surprise and there was also quite a long list of other sightings albeit not of anything in any great quantity. 

The Bill area produced 25 Willow Warblers, 15 Wheatears, 6 Tree Pipits, 2 Whinchats, 2 Sedge Warblers, a Mallard, a Yellow-legged Gull, a Yellow Wagtail, a Nightingale and a Dartford Warbler on the land and 6 Common Scoter and 4 Balearic Shearwaters on the sea, whilst elsewhere there were 2 more Sedge Warblers at Reap Lane and 50 Ringed Plovers, 50 Dunlin, 5 Teal, 2 Yellow-legged Gulls and singles of Redshank, Greenshank and Whimbrel at Ferrybridge.

The Obs garden moth-traps keep turning up the odd scaps of quality - today it was a single Convolvulus Hawk-moth - without there being any sign of a more general upturn in immigration; the pick of the rest of the morning's catch were 7 Silver Y, 3 Rusty-dot Pearl, a Diamond-back Moth and a Dark Sword Grass; Chocolate-tip and Mouse Moth were both year-ticks. 

  

 

   Jersey Tiger - Portland Bill, August 1st 2007 © Martin Cade

  August 1st

Something of a repeat of yesterday - fine weather and nothing more than a thin sprinkle of migrants. The Bill area produced totals of 20 Willow Warblers, 12 Wheatears, a Ringed Plover, a Dunlin, a Common Sandpiper and a Sedge Warbler on the ground, small numbers of hirundines overhead and 23 Common Scoter and single Manx and Balearic Shearwaters overhead. Equally small numbers of common migrants elsewhere included 16 Dunlin at Farrybridge and a Sedge Warbler at Reap Lane.

The only immigrants in the Obs garden moth-traps this morning were 9 Silver Y, 6 Rusty-dot Pearl, 2 Dark Sword Grass and a Pearly Underwing; Barred Rivulet was a year-tick.

Late news for yesterday: a Common Scoter was at Ferrybridge.
