5th September

What a shocker: rain set in only an hour or so after dawn and continued for the duration of day and well on into the night. Birding opportunities were necessarily very limited although the sea and Ferrybridge did get good coverage. The wash-out on the land was disappointing since there looked/sounded to be a good bit more about than yesterday but in the short time available nothing more than 3 Spotted Flycatchers and a Redstart in the vicinity of the Obs could be found amongst the conspicuously numerous phylloscs and Wheatears. The Ferrybridge wader tally was constantly changing, but 29 Knot, 8 Sanderling, 3 Little Stints, 2 Bar-tailed and a Black-tailed Godwit, a Whimbrel and a Redshank were there at various times amongst the routine array; Sandwich Terns reached a peak of 21 there. Balearic Shearwaters were again ever-present off the Bill where there were often 50 or more at a time and likely still well into the hundreds altogether; plenty of Manx and a single Sooty Shearwater also passed by there.

Today's rainfall radar images (this one was from 1pm) were something to make the heart sink - or if you like seeing migrating/disorientated waders they were something to get excited by:


Ferrybridge was one of the few places that was birdable today and, as so often happens in these conditions, there was a constant turn over of birds. These Black & Bar-tailed Godwits, Sanderlings and a Whimbrel were there at dawn before it rained © Pete Saunders:




...but with nightfall, the continuing heavy rain and the tide rising enough to cover the sandflats all coinciding at the end of the day there was some fantastic late movement to tap into. Three Little Stints dropped in for a few minutes...


...but the most compelling sight was the constant departure of noisy flocks of waders rising up into the leaden sky and heading away south...


...it was getting so dark by the time two successive flocks of Knot zoomed through that but for their  constant calling they were barely identifiable. Really, really exciting birding! © Martin Cade:


Today's wet weather did give us a chance to finish off a little project we were messing around with back in August. Bastard-toadflax Thesium humifusum is a rare-ish plant of good-quality calcareous grassland that grows here and there on the Slopes at the Bill; entomologists also know it as the only host-plant of two obviously equally rare-ish insects, the micro-moth Chalk Hill Ridge-back Epermenia insecurella and the Down Shieldbug Canthophorus impressus. Our particular interest has always been in the moth and as we hadn't seen that for a while we thought we'd try and get some in-situ photographs of it; this proved to be a lot more tricky than anticipated but did lead to the cobbling together of some video and stills that hopefully give a slight feel for what the plant and its bugs look like in the field. Many thanks to Erin Taylor, Mark Cutts, Martin King, Matt the Botanist and Jodie for various assistances - particularly for help with locating the plant in the first place which wasn't all that easy since most of it had already gone over for this year © Martin Cade:
