Life in grey and white

Today we've had heavy snow and very poor visibility. The good news is that the weather brought birds into the garden in good numbers, sadly though nothing new for my blip challenge, which I feel is grinding inexorably to a standstill. I'm still confident of reaching 40 - 2 more garden regulars and a wildcard. I've posted the feral pigeon today, because keeping this until my last bird might seem like an act of desperation, and also because this image seemed to fit the mood of the day. No prizes for guessing my 2 remaining "garden bankers", but you're welcome to have a go. The wildcard - well your guess is as good as mine. But that's birds for you! :-D
