One day soon, I may attempt to work out my year list from memory. I honestly haven't kept notes.
I know I've missed lots of fairly easy ones:
Barwit, Gropper, Garden Warbler, Merlin, Eider, Slav, Razorbill, Puffin spring to mind.
Equally, I've seen some good rarities:
Black Throated Thrush, Semi P, Little Auk, Montys, G O bird etc
So who knows, or indeed cares....
