Whatever they found, it must be interesting!
All jokes aside, what ARE these birds? The two large ones. You can see their scale by the sparrow in front of them. I've looked through my bird books and done several internet searches with little luck. I think they might be the juvenile form of something, but I'm just not certain.
UPDATE: So, they ARE European Starlings. They don't match the juvenile pictures in my books I guess because they're in the process of changing their coloration. I've seen that sort of thing with Canada Geese, where the older goslings look radically different as they begin to get their adult markings. I'd suspected they might be, but wasn't certain. Thanks for the help!
UPDATE 2: This picture was cleaned up for me by Animalartist16; the original was taken through a window, hence the slight fuzziness.
