Sparrowhawk double

It had to be a shorter session than usual at Billinge this morning because I had an appointment to go to but it turned out to be interesting nevertheless. There weren't many thrushes moving but over 2,000 Woodpigeons were counted going south by 9:00am (per CAD). A single Brambling was the first of the autumn and another or the same was heard again later. There were no warblers, not even a Chiffchaff, but Goldcrests found their way into the nets at regular intervals and a total of 13 were ringed. A couple of Sparrowhawks livened things up with a 1cy male being caught first and a 2cy female being caught in the same net an hour later. Catching 2 Sparrowhawks in the same session doesn't happen very often but the 3 previous occasion it has happened have all been in mid October like today's double act. The lively theme continued when a rather feisty Jay was caught and it did its best to take lumps out of me, as they usually do. The last net round produced a group of 5 Lesser Redpolls and, interestingly, 4 of the 5 were adult males which continues the predominance of adults in the Redpolls caught so far this month.

The female Sparrowhawk had an unusual and very hard accretion on the tip of one of its claws. I have never seen anything like this before and have no idea what could have caused it..

Ringing totals (retraps in brackets) for 15.09.18 were: Sparrowhawk 2; Jay 1; Coal Tit 2, Blue Tit 1; Great Tit 1; Goldcrest 13; Blackbird 1; Song Thrush 3 (1); Bullfinch (2); Lesser Redpoll 5. Total 29 new birds and 3 retraps.
