I love watchin the birds out my back- I feed them a varied selection of treats all year round to attract all different kinds.
I'm really shit at trying to identify them though.
Get and RSPB membership and their book Bob - even just the book from the library. It really helps. It's an amazing thing to do once you start. its quite addictive...but in a good way!
I love all their little personalities and behaviours. How they take turns at the food whereas others fight it out.
