I really hate it when birds fly into our windows. I heard a thump yesterday, then found this little guy on the ground looking dazed.
I picked him up, looked him over, then after chatting with him for a while I put him in the Greengage tree.
He stayed there for a while in the sunshine, looking around, then after about 15 minutes he flew off; probably with a headache.
I'm not sure what variety he is; a Serin maybe. Fare ye well little guy.
