An ex-goldfinch |
I noticed that a couple of the rooks on the school field have white pins and streaks in their wing feathers. I understand this is an animal protein deficiency in their diet, it seems quite common in carrion crows but I wouldn't have expected to see it in rooks, which have a more mixed diet. Perhaps it's been a bad year for worms and leather jackets, the long, hot Spring might have had an effect. Could also explain why there's only been a handful of juveniles on the field this year.
More bad news as I found the remains of a goldfinch on the path by the back door. No idea of the culprit, of course, though one or other of the local hairy hooligans is a likely suspect.
