A bird in the hand

This little fellow came to visit us tonight. After a collision with our window, he was a little stunned and quite docile. Anyone know what kind it is? He has a lovely greenish colour to him. (We'd just biked home from a soccer game - hence the bike gloves. The girls were brave enough to hold it with a glove on their hand.) We put him on a bench while we ate supper, and now he's gone. Hopefully, he flew away to a happy long life.
