Green Hairstreak
We finally woke up to the long-prayed for SE breeze with some cloud cover so there was a touch more anticipation than of late but it proved to be a quiet morning with few grounded migrants; birds of note comprised 4 Black Redstarts, another 377 Brent Geese out of the river and north at sea, 2 Chaffinches, 18 Common Scoter north, 2 Common Tern, 2 Dunlin, 2 Fulmars, 3 Kittiwakes, 5 Lesser Whitethroats, 3 Mediterranean Gulls, a Reed Warbler, 15 Sanderling, 9 Sandwich Terns, 14 Swallows south, a Wheatear and 5 Whitethroats.
Ringing: Starling 2, Linnet 2 (including the first fledged juvenile)
Angle-barred Pug of the form "unicolor" can be very common here. It used to be called Ash Pug with the subspecies living here, Tamarisk Pug with all three of these formally different, now lumped together as one species (I think that's right - according to the scribbled notes that I'm copying from anyway!)
