Rarity highlights have been at a bit of a premium this year so a White-winged Black Tern that flew through at Ferrybridge into the teeth of this morning's brisk easterly was a very welcome little event. With conditions again not at all conducive to a fall of migrants most of the day's numbers were overhead or on the sea and included 150 Yellow Wagtails over the Bill, 350 Swallows and 80 Sand Martins through over Ferrybridge and 55 Balearic Shearwaters through off the Bill; on the ground 5 Reed Warblers at the Bill was a good autumn total but little else posted a significant tally there or elsewhere. The Melodious Warbler from a couple of days ago made a reappearance at the Obs after escaping detection all day yesterday, whilst the miscellany of lesser frequent migrants included an Osprey south off West Cliffs, 2 Knot at Ferrybridge with singles of Hobby and Teal overhead there, and 2 Arctic Skuas and singles of Little Egret, Great Skua and Arctic Tern through off the Bill.
The White-winged Black Tern was the island's sixth record but the first since 1999 - Ferrybridge and the Bill are now neck and neck at three apiece. Since it literally flew straight through it was a sharp spot by Graham Bright and it was fortuitous that Pete and Debby were on station to capture what we think are the first photographs taken of any of the Portland White-winged Blacks © Pete Saunders (top two) and Debby Saunders (bottom):

No sooner had the wind shifted into the northeast - and freshened on very conspicuously for the morning at least - then both variety and numbers really perked up, with a Melodious Warbler trapped at the Obs and a passing Marsh Harrier on West Cliffs the pick of the arrivals. On the ground, Willow Warblers and Wheatears totalled 75 and 60 respectively at the Bill, where new Robins were much in evidence and the likes of 3 Redstarts, 3 Garden Warblers, 2 Spotted Flycatchers, 2 Reed Warblers and a Lesser Whitethroat provided additional interest. Numbers overhead included 400 Swallows, 100 Sand Martins and 40 Yellow Wagtails, with 10 Tree Pipits, 2 Snipe and a Golden Plover in with the mix. After their poor showing so far thus summer and early autumn a bumper haul of 325 Balearic Shearwaters passing the Bill was a very welcome return for the seawatchers, who also chipped in with 5 Gadwall and singles of Great and Arctic Skuas amongst others.
Several Bluefin Tuna and at least 20 Common Dolphins were off the Bill during the morning.
Immigrant moth numbers increased with overnight totals at the Obs that included 45 Silver Y (the highest total since 25th July) and 5 Vagrant Piercer Cydia amplana (the highest total this year).

Another little sprinkle of migrants today amongst which an Osprey over the Bill, 4 Garden Warblers at Culverwell and up-island singles of Redstart and Pied Flycatcher were about the best on offer. Numbers were nothing to shout about, with Tree Pipit, Sedge Warbler and Willow Warbler all only just getting into double figures at the Bill where the continuing lateness of the season was indicated by totals of just 7 Wheatears and 2 Yellow Wagtails. The sea was hardly more rewarding, with just 8 Balearic Shearwaters through off the Bill.

A heavily overcast sky and scarcely a breath of breeze were welcome conditions as dawn broke and it was soon apparent that there was a considerable improvement in migrant numbers, with 50 Sedge Warblers, 30 Willow Warblers, 9 Tree Pipits, 2 Reed Warblers, a Grasshopper Warbler and a Garden Warbler among the grounded selection at the Bill; the dearth of a variety of other usually routine fare such as Wheatears - just 2 were logged at the Bill and another 7 at Ferrybridge - and either of the commoner flycatchers - of which there were none - did however remain entirely baffling. Overhead passage was scarcely a feature until late in the day when upwards of 100 Swifts and 50 Sand Martins appeared over the Bill; earlier the first Hobby of the season had passed through at Ferrybridge. A steady trickle of departing Lesser Black-backed Gulls, 11 Balearic Shearwaters, 2 Yellow-legged Gulls, 2 Arctic Skuas and a single Great Skua provided interest offshore; of potentially much greater interest there was what looked to be a strong candidate for an immature booby sp passing by in loose association with some Gannets - although seen quite well for the short time it was in view it showed no signs of lingering and was quickly lost heading west.

The first calm morning of the week saw an early morning flurry of Sedge Warblers and Willow Warblers in both the garden and the crop fields. However, the highlight of the day was the first pair of autumn Rooks overhead. Ferrybridge continued to shine with: 140 Ringed Plovers, 40 Dunlin, 17 Turnstone, five Sanderling and singles of Redshank and Sandwich Tern.

Clearer conditions made for a much better passage day. The early morning saw an increase in overhead passage including a smattering of Sand Martins, six Tree Pipits and singles of Yellow and Grey Wagtail. The garden was much busier with over 30 Willow Warblers 'hu-wheating' from the tree tops, and a skulking Garden Warbler eventually revealing itself in the nets. Sea passage was also a lot more promising 15 Balearic Shearwaters, three Bonxies and a supporting cast of Kittiwakes and Lesser Black-backed Gulls. Wader passage was also notable with the Bill producing five Redshank, three each of Ringed Plover and Dunlin and two Turnstones to add to the Purple Sandpiper sighting at Ferrybridge.

A fog-bound and heavily damp morning brought little in the way of enthusiasm to the early proceedings of the day. As the weather began to clear through, it was with reluctance that we opened some nets and began emptying the moth traps. It was clear that there had been no falls of autumn migrants as seen along other parts of the coast so it was exceedingly surprising that the only bird of the day trapped was a Melodious Warbler just before lunch. Other migrants were few and far between with just singles of Wheatear and Willow Warbler at the Bill. Ferrybridge was its usual autumnal self with three Knot, three Sanderling and a Redshank among the lingering Terns.

A cool start to the morning was not indicative of the afternoon to follow, with clear blue skies and scorching sun. Passage migrants were thin on the ground with just four Sedge Warblers trapped alongside a Grasshopper Warbler in the crown nets and a smattering of Wheatears across the Bill and Ferrybridge. The warm afternoon saw a flying ant emergence and a formation of a feeding kettle of Swifts, Mediterranean Gulls and a Sparrowhawk. Ferrybridge was busy once more with 233 Ringed Plovers, 60 Dunlin, nine Sanderlings, six Turnstones and a Redshank.

Not that a day can have several halves but today was certainly full on contrasts, what with its drippingly damp, foggy start, its sunny but stickily humid afternoon and its bright, briskly breezy evening. Bird-wise, there was little to commend, with a lone Grasshopper Warbler the best of a woefully low tally of common migrants at the Bill; Ferrybridge was considerably busier including further increases to 277 Ringed Plovers and 14 Sanderling.
This odd, buffy-toned Dunlin has been at Ferrybridge for a couple of days now; we're guessing it's melanin-deficient in some way - there's probably a correct term for this but we haven't looked it up - but in the soft light this evening it cut a subtly pretty figure amongst its still very contrasty summer-plumaged congeners © Martin Cade:

Today didn't quite pan out as expected since the promised overcast skies didn't materialise until the evening and for the most part the day was pleasantly warm and sunny but underwhelming on the migrant-front. Sedge and Willow Warblers again accounted for the bulk of the passerine numbers on the ground but both were far less numerous that they'd been yesterday; in contrast, Ringed Plovers continued to increase with 252 at Ferrybridge by the end of the day. Variety included a Wood Warbler reported briefly at the Obs Quarry and the Green Woodpecker doing another early round of the Bill.
Had we have had time to scan through the night's nocmig recording before opening the nets we mightn't have been so surprised that one of the first migrants trapped after dawn was what seemed to be a quite early Tree Pipit; although there had been a couple of singles overhead at the Bill yesterday morning and a random single calling over the Obs after dark a few evenings ago it would usually still be considered early in the season for any numbers of them. However, the nocmig recorder logged 15 calls over the Obs last night so some of them are certainly on their way pretty promptly this year © Martin Cade:

A decent arrival of migrants has been a long time coming this autumn but the wind finally falling light under a clear but moonless sky presented promising-looking conditions today. Dawn saw the Crown Estate Field in particular hopping with Sedge Warblers and it wasn't long before the warmth of some strong sunshine saw Willow Warblers emerging in quantity; variety still wasn't a feature on the ground but overhead a steady passage of hirundines developed to further bolster the numbers. Eventual day totals for the Bill included 150 Sand Martins, 100 each of Swallow and Sedge Warbler, and 50 Willow Warblers, with nuggets in interest including 3 Yellow Wagtails, 2 each of Tree Pipit and Reed Warbler, a single Garden Warbler and an island oddity in the form of a Green Woodpecker. Ferrybridge was also busier, with Ringed Plover and Dunlin conspicuously more numerous at 182 and 70 respectively, and 9 Sanderling, 2 Redshanks and a Black-tailed Godwit of further note. The increase in waders was also noted offshore, with 9 Dunlin, 4 Ringed Plovers and 2 Whimbrel through off the Bill; passage of Lesser Black-backed Gulls was also gathering momentum and singles of Balearic Shearwater and Yellow-legged Gull passed by.
It's so rare for us to get to handle an adult male Yellow Wagtail - and with ridiculous thoughts of American vagrancy still at the back of our mind - that the distant sight of the dazzling underparts of this bird that turned up out of the blue in the bottom panel of a mist-net in the densest cover in the Crown Estate Field momentarily and amusingly set in motion thoughts of a repeat of the Yellow Warbler © Martin Cade:

An unexpectedly quiet start to the day amid what's otherwise turning out to be an unwelcome downturn in the weather afforded the opportunity to get amongst a few grounded migrants, with double figure totals of Sedge Warbler and Willow Warbler, and a lone Grasshopper Warbler logged at the Bill; wader numbers also improved again, with 8 Sanderling and 2 Common Sandpipers amongst the 60 each of Ringed Plover and Dunlin, and 17 Turnstones at Ferrybridge. Three passing Balearic Shearwaters off the Bill were all that showed up once the wind and rain returned by mid-morning.
6th August
A constantly gloriously sunny day spoilt only by the near gale force strength of the westerlies; however, it was certainly a day to forget on the birding front with 2 Balearic Shearwaters through off the Bill and a Great Skua over Ferrybridge the sum total of interest.

Having had such a good run of island firsts and interesting immigrants and dispersers we thought we'd more or less run out of superlatives for this summer's mothing happenings. However, nothing had prepared us for the unmistakable sight of the hugely engorged Y-mark of a Stephens' Gem in one of this morning's Obs moth-traps - not only a first for Portland and Dorset but also just the fifth record for Britain. To boot, this is a moth with a home range confined to the Americas which makes it an all the more staggering occurrence: hitherto, our highlight of the year had been the sight of a much-wanted Rose Plume in one of the traps a couple of weekends ago but we're guessing that had only strayed a couple of hundred miles from northern France to get here - Stephens' Gem really is in an entirely different league! © Martin Cade:
