A different feel today with a really brisk northeasterly having sprung up overnight and increasing cloud spilling in as the day went on. Visible migration was quite a spectacle for a while, with hirundines (mainly Swallows today) streaming through into the wind over anywhere that was being watched - sample counts suggested more than 2000 per hour were passing through into the wind at times during the morning. Most of the other expected late August over-flyers were well-represented, with oddities on the move that included a Marsh Harrier (additional to the lingerer that was still about) and a selection of other commoner raptors, along with the likes of a Green Sandpiper; a variety of other new waders dropped in, including 10 Knot, 2 Whimbrel, a Redshank and a Common Sandpiper at Ferrybridge. The sky might be filled but the bushes and the fields weren't: there were a handful of new Whinchats, Redstarts and Pied and Spotted Flycatchers dotted about but commoner warblers were conspicuously few and the likes of Wheatears were no more than thinly spread. Shearwaters remained a feature offshore, where upwards of 200 Balearics were ever-present off the Bill; Manx weren't quite so numerous today, whilst 75 departing Lesser Black-backed Gulls, 5 likely Black Terns, 2 Arctic Skuas and a Yellow-legged Gull were amongst the other movers there.
Yellow Wagtail and Spotted Flycatcher at the Bill today - the wagtail is colour-ringed and is evidently a bird from Salisbury Plain (the lettering on the colour-ring couldn't be made out so if anyone's about tomorrow do keep an eye out for this bird and see if you can get a decent view of it) © Steve Mansfield:
An interesting little event we've got involved with just lately has been the appearance of an unusual bug around the Obs garden. We don't 'do' bugs in any systematic way but last year we begun catching in the moth-traps specimens of something that was very distinctive but unfamiliar that we assumed would be a colonist from inland that we just hadn't had any previous experience of. This year they've continued to appear from time to time and word of their occurrence reached various bug specialists who quickly realised they were something hitherto unknown in Britain - it's also transpired that before we'd started seeing them at Portland John Gifford had caught one in a moth-trap in Weymouth in 2022; subsequently, we've caught specimens in the moth-trap in our garden at the Grove so we've no reason to suppose the bug isn't already widely established around Portland and perhaps elsewhere.
With its retrousse rear end this little bug's rather eye-catching and quite unmistakable; evidently it's a flatid planthopper of the genus Cyphopterum - this genus has a mostly Mediterranean distribution and none of the numerous species within it are known from Britain:
Despite a much stiffer northeasterly a fair catch of migrant moths at the Obs last night: 2 Mugwort Pearl sticticalis first this year; 6 vitrealis, 4 Porter's Rustics, 2 amplana, 1 Convolvulus Hawk best of the rest. Local specials incl late-ish Four Spotted
