I thought quail also, but when I showed the pic to someone who has hunted them he said they weren't. I just don't have a clue, there were 4 of them, 2 in the yard and the 2 in the picture.
Thank you for the answers! Wonder what they were doing in our back yard, they must have been very lost. I don't think a pear tree will do well with the snow in the back yard, but I do have a bowl full sitting on the counter That must have been what attracted them
