Rainy Day Robin

Getting a good bird photo through the (closed) kitchen window is a bit of a challenge, but the only option on a rainy day like today. (To be honest, it's also the best option on other days, as they are much less likely to take fright and flight).

Anyway, this cheery little chap was happy to sit still long enough for me to get a reasonable close-up, without too much reflected light. Any tips on shooting through glass will be welcome!
