Slightly sad state of affairs on two counts that today's green-and-yellow ringing highlight wasn't the Golden Oriole that briefly entered one of our ringing areas but this Greenfinch that's only the third ringed here this year - last year we only ringed one! Day's migrant tally down to just 36 birds

Reduced numbers of migrant moths at the Obs last night: 71 Diamond-backs, 19 Rusty-dot Pearl, 2 Silver Y, 1 Dark Sword Grass, 1 Turnip, 1 Small Mottled Willow; Maiden's Blush a stray of interest.

Quite rewarding on the ringing front again today, particularly under patchy cloud at dawn - sadly, the migrants upped and left very quickly as soon as the sky cleared a couple of hours into the morning. Bill total of 81 included 26 Whitethroats, 16 CCs, 13 WWs, 6 Sedge W, 5 Reed W & 5 Garden W.

think i got to 12 species for certain, almost sure i had a very brief glimpse of a lulworth too and probably common blue in flight.

mainly butterflies today but a late wheatear through tout, barn owl and little owl at verne moat and a couple of lesser whitethroat belting it out, this one along the moat perimeter fence

Bit of a sea change on the ringing front at the Bill today - about time too! 79 new birds with the total of 19 species the highest so far this year. Whitethroats strongly to the fore on 22, Willow Warbler next best on 14.

A Brindled Beauty from the Grove the pick of last night's moth catch - still fewer the 10 records for the island. Migrant totals at the Obs: 55 Diamond-backs, 18 Rusty-dot Pearl, 2 Silver Y, 2Turnip, 1 Small Mottled Willow. Despite cloudy skies Painted Ladies everywhere about the island by day.

And a little bit of nocmig action from last night: we actually happened to step outside to see if there was anything audible just as this flock of Ringed Plovers and Dunlins were circling around over the Obs - it had fogged up at the time (the Bill lighthouse fog signal is sounding every 20 seconds during this recording) and the bright lights of the Obs garden moth-traps were illuminating the fog enough that it seemed like the waders were temporarily disorientated and whirring around just overhead:

Sure sign it's poor for birds when the local school call in on us and there are so few migrants coming from the mist-nets that for some hands-on natural history we're reduced to pond-dipping for newts with them!

Dawn looked to again be disappointingly quiet but a cloudier and drab spell that unfolded a little way into the morning saw migrants drop in steadily, with 40 Wheatears and 30 each of Willow Warbler and Chiffchaff joined by the first 10 Spotted Flycatchers of the spring along with a varied selection of less frequents that included 10 Lesser Whitethroats, 6 Sedge Warblers, 5 Garden Warblers, 2 Redstarts and singles of White Wagtail, Whinchat, Reed Warbler and Ring Ouzel; overhead arrivals at this time included 40 Swifts, 2 Hobbies and an Osprey although the usually commoner diurnal migrants like hirundines were oddly few. The sea was also rather quiet, with 200 Manx Shearwaters, 14 Common Scoter, 3 Great Northern Divers and 3 Arctic Skua logged at the Bill and 20 Whimbrel through at Chesil where the lingering Mediterranean Gull total topped three figures.
Lesser Whitethroats were really well represented in today's arrival of migrants - this one was visiting a garden at Sweethill © Pete Saunders:
Suggestions of a little bit more happening so far this morning in much cooler, drabber and breezier conditions: first Spotted Flycatcher of the season, 2 LWTs and 2 Sedge Warblers from the mist-nets; a Ring Ouzel seen at Culverwell

Beautiful vistas, enticing habitat but conditions still way, way too nice today to drop many migrants - this Redstart one of the few of note amongst the meagre dozen trapped between the Obs and the Crown Estate Field this morning

4 or 5 small blue at the church ope cove end of bottomcombe today , a dingy skipper there was also nfy for me today and more bizarrely red admiral. several wall brown at yeolands quarry pool but no dragons of any sort.

At the well today, a very cool recovery of a Willow Warbler previously ringed in Norway. More details to follow once we know them. @portlandbirdobs.bsky.social #culverwell #birdringing

It was fab to be back bird ringing at Culverwell with @slashercutts.bsky.social this morning. Not many birds but exciting to recover a Willow Warbler previously ringed in Norway as well as a couple of other warblers.

A few migrant arrivals on a blustery Portland this morning. Two Whinchats (distant record pic of one), one Yellow Wagtail and many Swallows at Barleycrates Lane plus Willow Warbler at the Bill. @portlandbirdobs.bsky.social @dorsetbirdclub.bsky.social

Bit of a varied day at the office today: seawatching, vismigging, a school visit, ringing - you name it, we managed to get a bit of it today...

Sensory overload at the Bill tip this morning what with there still being c8000 gulls offshore; passing seabirds poor with a single BtDiver the best for us. Lots of inbound vismig, mainly Swallows but multiples of Swift & Yellow Wagtail + single Merlin; weary Collared Dove in off.

Fun evening seawatch on Chesil but doubtless less fun for the succession of waders finding it really hard work to get over the beach/Portland Harbour into the teeth of a blasting easterly; nearly 150 each of Bar-tailed Godwit and Whimbrel + singles of Grey Plover and Knot. Great migration watching!

21st April
We can't make head nor tail of all of today's reports from around the island but our totals included 290 Sandwich Terns, 110 Bar-tailed Godwits, 38 Whimbrel, 3 RtDivers, 2 Arctic Skuas and a GNDiver from the sea and 6 Redstarts, 3 Whinchats and singles of Hobby, Yellow Wagtail and LWT from the land.

Ferrybridge 21/4 Eve. A group of 18 Bar-tailed Godwit & 7 Whimbrel dropped in. Washed & fed. 5 the Whimbrel moved on quite quickly calling, the Barwits left later. One existing ringed barwit unmoved by the fuss. Magic. 45 Dunlin most spl, 8 Ringed Plover, 3 Turnstone @portlandbirdobs.bsky.social

Bitterly cold NE wind on the Chesil this morning but a good watch nonetheless. Little Ringed Plover, Merlin, 64 Whimbrel, 23 Barwit, Arctic Skua, Mute Swan on the sea, Swift + Hirundines arriving, lots of WW and some Wheatear in off. Too cold to continue past 9:15, more clothes needed tomorrow!

about 15-20 spikes of green winged orchid suddenly appeared in the new normal spot at verne common. looking at next weeks weather, whilst it may be good for birding it may also burn these off quick.

Well we were hoping for a scarce the day after the fall but imagined something a little different to the Siberian Chiffchaff just trapped in the Crown Estate Field. Far lower numbers/variety than yesterday coming from the mist-nets so far this morning.

Another Redstart turned up in the garden this afternoon spending most of its time deep in the apple tree. Fewer immigrant birds today with 3 Blackcaps and a few Willow Warblers

female redstart near southwell barns, males at reap lane and barleycrates. at least 4, probably 5x whinchat at reap lane.

small copper at bottomcombe, still no small blue after the conservation lash up, but another clouded yellow fly through and a hummingbird hawkmoth of note
