It's been a good few days for the London and Surrey birding fraternity - an Ortolan here, an Osprey there - all decent stuff for the inland patcher. With a slightly delayed start, and tweets coming in reporting a bit of viz-mig in southern Surrey, I entered Canons Farm in a state of anticipation.
After half an hour it seemed as if the birds had decided to bypass me. But then a few hirundines started to show, then a Yellow Wagtail called, a Lapwing rose up from Harrier Field and left westwards and everything became a lot more promising. The four hour session resulted in: 7 Cormorant (a messy flock north), 6 Common Buzzard, 2 Sparrowhawk, 1 Peregrine (an immature bird trying its luck with Woodpigeons at Tattenham Meadow, maybe one of this years Sutton birds), 1 Lapwing (grounded in Harrier Field then left westwards), 2 Common Swift, 420 Swallow (mostly heading SSW), 80 House Martin (likewise), 6 Yellow Wagtail (all singles flying S or SW), 1 Whitethroat, 6 Chiffchaff and 3 Yellowhammer. Grounded migrants (bird in general really) were sparse.
The sun had plenty of warmth, and despite a stiff breeze there were many butterflies on the wing, including Red Admirals, a Painted Lady and a Clouded Yellow (the latter at Circle Field). Most numerous were Comma (below) and Speckled Wood (bottom).
