The Birds.

Not a sharp photo as it was taken quickly on auto setting, but these appear to be young blackbirds. About ten minutes before I took this, about eight of them hit the front window. When I went outside to check they were OK, a flock of over fifteen flew out of one of my tall conifers. They later settled on a tree across the street. I managed to grab my camera and get them as they left that tree.
I thought at first they were young starlings, but their call and song was definitely that of a blackbird. If anyone knows of blackbirds flocking like this, can you let me know?
