There was lots of enjoyment to be had from today's migration happenings, with the continuing settled weather seeing plenty of birds arriving on all fronts across the island. On the ground, Wheatears were conspicuously abundant, with a likely very conservative minimum of 100 recorded around the Bill where multiple waves of birds raced through throughout the morning. Other grounded arrivals were more thinly spread: a Willow Warbler was an on-cue first of the year, with 25 Chiffchaffs, 3 Blackcaps and singles of Firecrest and Greenfinch also logged. Overhead, Meadow Pipits and Linnets continued to move through, with 193 and 45 logged respectively in a sample hour on West Cliffs, whilst other visible migrants included 30 Sand Martins, a Short-eared Owl, the year's first Ring Ouzel, 2 Siskin and a Reed Bunting. At sea, a Long-tailed Duck - a genuine Bill rarity these days - was the pick of a passage that also included the year's best Gannet total to date of 415, along with 141 Common Scoter, 9 Red-throated Diver and 7 Shelduck.
Back to the Mecca that is PBO @portlandbirdobs.bsky.social for a Trustees' meeting three days after it's 65th anniversary. Real bonus of 22 birds of 10 species ringed today with a Mega, 5m Greenfinch,(only 1 ringed in 2025) 1st Willow warbler of year, 7 Cc, 3 Blackcap, 2 Goldcrest and a Firecrest.

We don't really catch all that many Chaffinches so it was a surprise this morning that it should be one of them that accounted for our first ringing 'control' of the year. These days, the BTO is wonderfully efficient with reporting back with the ringing details of captures like this and by the end of the afternoon we'd already learnt that the bird had been ringed by our old friend Ian Dodd just across on the mainland at Littlesea, Weymouth. Ian had originally ringed the bird on 16th November last year - a timing that suggests it was perhaps a migrant arriving to spend the winter in Britain and we'll hazard a guess that it's been in the Weymouth/Portland area ever since and is just now departing back to its natal area on the continent © Martin Cade:

...and a migrant moth: a Silver Y from the Obs moth-traps last night - our first since 2 in mid-January

A perfectly birdable morning revealed no evidence of migration resuming in earnest. The only passerines of note at the Bill were lingering singles of Blackcap and Firecrest. A tiny bit more passing on the sea there included 5 Red-throated Divers and 2 Manx Shearwaters. Elsewhere, the first 6 migrant Pale-bellied Brent Geese of the spring dropped in at Portland Harbour.
Some late snippets of news for yesterday, 14th: a Merlin in off the sea at the Bill, 2 Black Redstarts in the East Cliff quarries at the Bill, 2 Firecrests at Sheat Quarry and 2 Siskins over Southwell.

An unexpectedly lovely day that didn't really deliver on the migrant front. A small flurry of new arrivals at the Bill included 8 Wheatears and a Sand Martin that were certainly new, along with several Goldcrests and singles of Black Redstart, Blackcap and Firecrest that were likely or confirmed lingerers; elsewhere, 3 Blackcaps were at Sweethill and a Black Redstart at Reap Lane. Three Red-throated Divers and a single Great Northern Diver were about all that could be mustered from the sea at the Bill.
In the absence of many birds it was the perfect afternoon for a fruitless scour of Church Ope Cove/Pennsylvania Castle for Large Tortoiseshells...

Unyielding gloom again today and in the increasingly misty conditions the constituents of the day's arrivals changed, with fewer Chiffchaffs and crests but more thrushes and finches. This had been hinted at overnight when the Redwing loggings on the nocmig recorder at the Obs upped to 117 from the low single figure totals that had been the rule during the last week or so. Nine more were logged there through the morning when 23 Chaffinches, 6 Blackbirds, 2 Song Thrushes and a Brambling also passed through. Grounded arrivals were sparse, with barely more than the odd singles of Wheatear, Chiffchaff and Goldcrest at the Bill; a lingering Blackcap occasionally in song was also at the Bill, with 2 more in song at Verne Common where there was also a currently locally very noteworthy total of 7 Greenfinches.
When you see the state of some of the bedraggled small migrants pitching up on the shore at the Bill tip on a damp day like today it does make you wonder how many others got too waterlogged during their Channel crossing and didn't make it - this Chiffchaff was a lucky one © Jodie Henderson:

The blanket of fog had cleared overnight but only to reveal that migration was at the lowest of ebbs. The odd singles of Blackcap, Chiffchaff, Goldrest and Firecrest were about at the Bill but several looked to be lingerers rather than new arrivals. A tiny bit more action overhead included 3 Lapwings along with a handful of pipits and wagtails. The sea was busier, with decent totals of 362 Kittiwakes and 182 Gannets through off the Bill along with 55 Common Gulls, 29 Cormorants, 16 Lesser Black-backed Gulls and 7 Red-throated Divers.

Great to be back at @portlandbirdobs.bsky.social even for a very fleeting visit this morning. Enjoyed the wintering flock of Purple Sandpipers and a steady up-channel passage of Kittiwakes before a day with swans at Abbotsbury enlivened by occasional visits from a White-tailed Eagle

16th-24th February
After a long barren spell the gradual introduction of milder and more more settled conditions has perked up interest no end, with 24th seeing the arrival of 2 Fieldfares and singles of Chiffchaff, Firecrest and Greenfinch at the Bill, 11 Stonechats and a Black Redstart at Reap Lane, a wandering Marsh Harrier overhead and 17 Common Scoter through offshore (...together with a handful of Redwings, Song Thrushes and Robins, and singles of Oystercatcher and Curlew logged overnight by the nocmig recorder at the Obs). Aside from routine winter fare, highlights during the preceding days concerned a released White-tailed Eagle overhead at Weston and Chiswell on 20th and a extremely unexpected island rarity in the form of a Nuthatch near Nicodemus Knob on 22nd.
After a few days when Lesser Black-back Gulls constituted the only signs of inbound passage at the Bill...
