16th October

Quite an oddity of a day, with the complexion being set early when the first two warblers out of the mist-nets at the Bill were both Yellow-browed Warblers; however, the less said about what followed on the ground the better, since it was pitifully quiet for new arrivals everywhere with only the long-staying Red-backed Shrike salvaging the day for most visitors. Fortunately, overhead passage was far stronger and included a record total of 13 Woodlarks over the Bill. Further interest was provided by bugs, with the Monarch butterfly watched seemingly arriving in off the sea at the Bill tip a fine highlight and a Vagrant Emperor dragonfly also showing up during the hunt for the Monarch. Whether a Yellow-browed Warbler heard later in the day at Southwell was one of the Bill birds moving on wasn't established, but further interest around and about included 2 each of Great Spotted Woodpecker and Dartford Warbler, along with singles of Water Rail, Merlin, Black Redstart, Cetti's Warbler and Siberian Chiffchaff - the latter two both lingerers rather than new arrivals. The day's numbers were all overhead, with Bill totals form the morning of 4500 Wood Pigeons, 550 Meadow Pipits, 400 Linnets, 390 alba wagtails, 82 Skylarks, 70 Stock Doves, 70 Chaffinches, 25 Greenfinches, 15 Siskins and plenty of randoms including a lone Marsh Harrier.

15th October

After early signs that didn't look at all promising in a brisk and dreary southwesterly today actually ended up passing off quite successfully, with single Yellow-browed Warblers at Avalanche Road and the Grove and singles of Siberian Chiffchaff, Caspian Gull, Dartford Warbler and the lingering Red-backed Shrike and Cetti's Warbler at the Bill, with further lustre provided by a spread of less regulars that included 4 Great Spotted Woodpeckers, 2 Firecrests and singles of Sooty Shearwater, Merlin and Black Redstart. Apart from the odd patch with Chiffchaffs still in plenty commoner migrants weren't much of a feature although 7 Redwings represented their highest total so far this month.

With the nights drawing in and some noticeably cooler weather on the horizon, it's hard not to find your mind wandering back to the balmy nights of summer and what was another successful season of Storm Petrel ringing at the Bill. Across 11 sessions (and one or two duds early and late in the season when we tried but didn't actually catch anything!), a total of 52 new birds were ringed, marking the third highest annual total after 121 in 1994 and 66 in 2025. The high encounter rate of Storm Petrels after ringing always produces fascinating movement data and this year was no exception, with 12 birds captured already sporting rings from elsewhere - 5 from Alderney, 4 from Skokholm, 2 from France and 1 from the Isles of Scilly; in addition, 14 Portland ringed birds were recaptured away from the island, with 12 from Alderney, 1 from the Isles of Scilly and 1 from St Abbs Head.

14th October

Plenty of movement afoot today although the majority of it concerned overhead passage and grounded arrivals were decidedly fewer than might have been hoped. The vismig over the Bill was pretty decent and included 4060 Wood Pigeons, 490 Linnets, 450 Meadow Pipits, 220 alba wagtails, 150 Skylarks, 120 Goldfinches, 110 Chaffinches, 92 Stock Doves, 62 Jackdaws, 42 Greenfinches (...remind us when we last had a total as high as this?!), 7 Siskins, 3 Bramblings and a Woodlark. Sadly, numbers on the ground were far, far lower with 4 Long-tailed Tits, 3 Great Spotted Woodpeckers, 2 Dartford Warblers, a Corn Bunting and the lingering Red-backed Shrike and Cetti's Warbler the best of it at the Bill amongst the thin spread of Blackcaps, Chiffchaffs and other routines. Were it not for the continuing constant presence of Bluefin Tuna, a lone Sooty Shearwater would have stolen the show offshore.

Not that we were trying to, but this morning we inadvertently recaught the Red-backed Shrike on one of our rounds of the Crown Estate Field mist-nets; pleasingly, this revealed it has been replenishing reserves quite well and had increased its weight from 31.9g when it first arrived six days ago to 33.8g today © Martin Cade:

Portland Day 3 - Wasn't great! Although the standout highlight was the Red-backed Shrike re-trapped, my first seen in hand since a female I caught in 2013. A Corn Bunting, quite a good number of Stonechat, Robins and Dunnocks revealed some movement afoot but little esle to show for the legwork.

13th October

A murky, damp and very windy night - conditions that dragged on for a while after dawn - didn't look at all likely to have done us any favours and once the clearance arrived fieldwork largely drew a blank. The Red-backed Shrike did resurface at the Bill, with a couple of Great Spotted Woodpeckers and a Cetti's Warbler also likely to be lingerers but a Merlin, a Reed Bunting and fair numbers of Blackcaps and Chiffchaffs were all that could be mustered on the ground. It was just as slow overhead, with a handful of Siskins the only variety amongst the trickle of departing Swallows and Linnets. With the wind quickly veering into the northwest the only worthwhile rewards from the sea were 3 Arctic Terns and 2 Arctic Skuas.

12th October

For a day that dawned downright miserably - windy, mizzly and with almost no visibility - and promised nothing more than a nice lie-in, being salvaged by a half-decent seawatch seemed like a pretty good result, with totals of 2500 auks, 1000 Kittiwakes, 14 Arctic Skuas, 13 Sooty Shearwaters, 12 Common Scoter, 2 Great Skuas and singles of Great Northern Diver, Common Tern and Arctic Tern accumulated at the Bill. There were a few new arrivals on the land that included 4 Redwings and 10 Song Thrushes amongst the light scatter of Wheatears, Blackcaps and Chiffchaffs at the Bill.

Portland Day 1 - Yes, I'm at it again! A slow start with strong S wind + stubborn drizzle, eventually a few hundred meters of sea became visible so that was the order of the day! 13 Sooty, 9 Arctic Skua, Great Skua, Arctic and Common Tern, GN Diver, 2k Auks, 800 Kittiwake, better than expected!

11th October

The return of quiet conditions was welcome and produced plenty of passage although perhaps not quite the quantity of grounded arrivals that might have been hoped after a turbulent interlude. The day's numbers were overhead, with 2450 Wood Pigeons, 420 Linnets, 200 Meadow Pipits, 140 alba wagtails, 70 Goldfinches, 60 Skylarks, 45 Chaffinches and 24 Stock Doves the higher totals amongst the morning movers over the Bill. On the ground, 100 Chiffchaffs and 40 Blackcaps made up the bulk of the Bill totals, with the lingering Red-backed Shrike and Cetti's Warbler, at least 3 Great Spotted Woodpeckers, 3 Dartford Warblers and 2 Long-tailed Tits providing the best of the quality there; at least another 3 Great Spotted Woodpeckers were elsewhere on the island. Two Wigeon, a Brent Goose and an Arctic Skua were the pick from some unrewarding seawatching at the Bill.

10th October

What with a nagging, stiff northwesterly a constant feature routine birding wasn't easy again today but there was some movement to tap into, notably including the first signs of Wood Pigeons getting going, with 360 leaving to the south at the Bill. The Red-backed Shrike lingered on to entertain weekend visitors, with a continuing Short-eared Owl also on offer at the Bill. Sheltered spots still harboured plenty of Blackcaps and Chiffchaffs but beyond these and the likes of a Redstart and a Goldcrest at the Bill there wasn't really much to excite in the common migrant line. A lone Balearic Shearwater was the only worthwhile sighting on the sea.

9th October

A stiff westerly that set in overnight freshened towards gale force as the day went on and scuppered most serious fieldwork today. The Red-backed Shrike was still present in the Crown Estate Field, singles of Merlin and Short-eared Owl were new at the Bill and 2 Purple Sandpipers were still present there but otherwise little more was logged on the land than a scatter of Chiffchaffs in sheltered spots and the Ferrybridge Brent Goose flock that had increased to 116. Singles of Balearic Shearwater and Arctic Skua passed through on the sea at the Bill.

8th October

While quantity was again a feature, with Blackcap and Chiffchaff both topping 150 on the ground at the Bill alone and lots of overhead passage to get amongst, quality won out today with a new Red-backed Shrike trapped in the Crown Estate Field stealing the show. As has been the case so far this month, Meadow Pipit, Blackcap, Chiffchaff and Linnet dominated the grounded totals, but further interest at the Bill included singles of Snipe, Great Spotted Woodpecker, Cetti's Warbler and Dartford Warbler. Overhead totals at the Bill included 850 Meadow Pipits, 375 alba wagtails, 360 Linnets, 140 Goldfinches, 50 Chaffinches, 35 Skylarks and 16 Song Thrushes, with a lone Woodlark the best of the oddities. Offshore, 2000 auks and 400 Mediterranean Gulls passed the Bill but there was precious little else of note.

On the ground, Chiffchaffs are still pretty abundant and are popping up all over the place, often well away from their usual haunts in the trees...

...but, scarcities aside, a lot of today's interest came from overhead passage with, amongst others, the strongest passages of alba wagtails and Song Thrushes so far this autumn and yet another Great Spotted Woodpecker © Martin Cade:

7th October

Today saw a rather unhelpful set of conditions to contend with as persistent bands of rain for the better half of the morning were gradually replaced by an increasingly blustery and cold northwest wind. Despite this, it was clear that the overnight rain had dropped a few migrants our way, with Chiffchaffs once again in bountiful supply as well as a single Redwing from the Obs garden and, from the comparative shelter of private gardens at Southwell and Weston respectively, new arrivals in the form of both Barred Warbler and Yellow-browed Warbler. Whilst the looming grey clouds seemed to dissuade many of the routine diurnal movers from departing over the island, several scarcer birds were recorded overhead with singles of Great White Egret, Cattle Egret, Short-eared Owl and Marsh Harrier at the Bill/Southwell. Unsurprisingly there were those that decided to stick it out in the dreary weather, with the lingering Cetti's Warbler still at Culverwell and yesterday's Hobby continuing its aerial assault on the migrant Red Admirals.

6th October

It was another busy autumnal day with a plentiful spread of new arrivals that included several on-cue firsts for the season, with 1 or more Dartford Warblers at the Bill along with singles of Redwing and Ring Ouzel in the middle of the island. Whilst Blackcap numbers appear to have waned in the recent settled weather, the same could not be said for Chiffchaffs, with 400 recorded from the Bill alone and reports of many more from the denser vegetated patches further up island. A varied list of less frequents were also on offer, with 2 Pied Flycatchers, a lingering Cetti's Warbler plus singles of Great Spotted Woodpecker, Garden Warbler, Grasshopper Warbler, Whinchat and Common Sandpiper present as well as 3 Woodlarks, 2 Golden Plovers and a Hobby overhead. The sea was comparatively poor, with just 15 Dark Bellied Brent Geese of note.

5th October

A pretty ripping morning saw a good cloud cover and no more than a waft of a breeze drop a succession of scarce migrants that included 4 Yellow-browed Warblers, a Little Bunting, a Siberian Chiffchaff and a Cetti's Warbler at the Bill and another Yellow-browed Warbler at Southwell; the long-staying Barred Warbler was also still at the Bill, whilst a further miscellany of irregulars around the island that included the likes of multiple Great Spotted Woodpeckers and singles of Hobby, Woodlark and Firecrest all added to the excitement. These goodies arrived in tandem with a hatful more Chiffchaffs and Blackcaps - including 300 and 150 respectively at the Bill alone - and lots of other grounded routine migrant variety, along with a steady if numbers-wise less impressive flow of visible migrants overhead; the tardy or interesting in other ways list from around and about included 4 Yellow Wagtails, 2 Redshanks, 2 Purple Sandpipers and singles of Golden Plover, Common Sandpiper, Whimbrel, White Wagtail and Whinchat. There were rather too many distractions for full attention to be paid to the sea but off the Bill a resurgence in departing Lesser Black-backed Gulls was noted along with the recently customary 2000 or more auks and singles of Sandwich Tern and Arctic Skua.

4th October

The loveliest of days to be out birding in unbroken sunshine and summer warmth - conditions that wouldn't usually be viewed as favourable for a good drop of migrants but in the event there were birds in quantity everywhere. The trio of Meadow Pipit, Chiffchaff and Blackcap accounted for a good proportion of the groundings - reaching totals of 1000, 300 and 200 respectively at the Bill alone - but there were strong showings of good range of other arrivals amongst which shorter-range migrants such as Dunnock, Robin and Stonechat were particularly prominent; thrushes have barely figured at all so far this autumn so the first Song Thrush of the season was hopefully the vanguard of plenty more to come. Overhead passage wasn't quite so prominent with hirundines rather oddly almost completely absent, but totals of 800 Meadow Pipits, 280 alba wagtails, 200 Linnets, 65 Skylarks and 35 Chaffinches were all worthwhile at the Bill, with singles of Great White Egret and Woodlark there and 2 Bramblings and a Ring-necked Parakeet over Coombefield adding some spice. Sea interest perked up a little, with 3000 auks, 40 Dark-bellied Brent Geese and 18 Wigeon of note off the Bill.

3rd October

A veil of light cloud overhead that marked the dreg end of a weak weather front departing very slowly southeast did us a favour today and dropped a steady arrival of a varied selection of mid-autumn migrants. Amongst the routine fare there were a couple of best-forgotten frustrations in the form of a likely non-British Yellow Wagtail flying straight through and a maybe Olive-backed Pipit heard and watched dropping into Culverwell but subsequently vanishing; scarcities that got a better grilling were limited to a presumed Siberian Lesser Whitethroat trapped at Culverwell and an Osprey departing to the south off the Bill, whilst less frequent migrants included 10 Long-tailed Tits, 3 Great Spotted Woodpeckers and a Firecrest at the Bill and 2 Pied Flycatchers and a Woodlark around the centre of the island. Although the likes of Blackcaps and Chiffchaffs weren't especially well represented there were a lot of other seasonable migrants to get amongst, including good groundings of alba wagtails and Meadow Pipits together with burgeoning flocks of off-passage Linnets and big increases in Robins and Dunnocks in particular. Overhead passage at the Bill included 700 Meadow Pipits, 220 Linnets, 130 alba wagtails, 24 Skylarks, 23 Chaffinches and 7 Greenfinches, whilst the sea remained quiet there with little more than 130 Mediterranean Gulls, a Red-throated Diver and an Arctic Skua to show.

Although there were one or two scarcer migrants on offer included the departing Osprey © Martin Cade and a couple of Pied Flycatchers © Joe Stockwell...

Something of a really frustrating "one that got away" this morning. This Yellow Wagtail appeared to be tagging a flock of Skylark, giving quite an odd, buzzy type call, followed by more descending flava'ish calls. Immediate thought was thunbergi but sadly without better views it wasn't clinched.

2nd October

No great change in our fortunes today, with overhead passage a little more conspicuous but grounded arrivals notably inconspicuous. Visible passage over the Bill included 600 Meadow Pipits, 310 Linnets and 130 alba wagtails, with 2 Merlins and a Hobby amongst the tag alongs; elsewhere, the autumn's first Redpoll was over Coombefield. The decidedly thin spread of arrivals on the ground included another autumn first in the form of a Short-eared Owl at the Bill, a Firecrest at Coombefield/Thumb Lane and a late Whimbrel at Ferrybridge but only very low totals of more routine fare; a brief Barred Warbler at the Bill was likely to be the lurking lingerer although it couldn't be established if it was a ringed bird or not. Auks and Kittiwakes totalling 1500 and 580 respectively made up most of the numbers off the Bill, with 3 Balearic Shearwaters the only particularly worthwhile sightings amongst them.

Stiffiish SW going more S overnight, with ..again a warm, sunny day did little for new birds at PBO. @portlandbirdobs.bsky.social . A tardy total of 13 birds from CEF, with 5 from the garden! in 9 hrs! Robin4, MeadpIp 6, Blakcp2, CC 3, & Swallows 3. Retrap Robins order of the day and Grey Wagtail.
