Big Garden Birdwatch

This morning I did the RSPB 'Big Garden Birdwatch' and for once, no-one seemed to have warned the birds as, instead of sitting for an hour staring at an empty garden like normal, I had lots of different birds down and counted. This Rook must have had something bothering him; although it looks as though he's doing the Hokey-Cokey he was in fact having such a good scratch that in the last shot he finally lost his balance and fell off the fence.
