The beaches at Birsay were covered in alba wagtails this afternoon and almost all of them were M.a.alba. I counted 53; 21 on the bay beach north of the burn and the rest on the links beach. I only saw three or maybe four yarrellii. These are amazing numbers. Interestingly they all called like yarrellii and I didn't hear the Grey Wag like call that I've sometimes heard from this form. At least three Whimbrel over whilst we were there and 5 or 6 Wheatear on the Links beach.
Earlier in the day Arctic Tern was added to the "from the garden" list courtesy of three then six on Loch of Bosquoy. A wader seen briefly flying between The Shunan and eventually landing around Bosquoy may well have been a Pec but although I saw it well it was a distant and fairly brief view so best forgotten. I went down to Bosquoy to look for it but to no avail although did count the Tufted properly 386.
In the garden were a pair of Siskin and a flock of what I think were Pink-feet stormed through at tree top level, 35 of them, before gaining height as they headed north west, presumably they were dodging a Peregrine.
At the end of the day a summer plumaged Dunlin was on The Shunan and added to the list.
Moth trapping last night produced but one moth - Hebrew Character, something must have gone wrong surely, although it was cold.
