My aunt took these shots while visiting Presqu'ile Provincial Park (Southern Ontario), and asked for identification. I thought (and still do to a degree) that it was a tree swallow; but she insists that it was bigger than a robin, and that she is almost positive that it is not a swallow of any kind. I can't think of anything else that fits these pictures. Can anyone give me a hand?
If you click on the photo (once in Webshots) you can see it full screen.
Another clue that I forgot. She said that the branch is over water (I'm guessing L.Ont.). To me, that would again suggest swallow, as I've seen them scooping up bugs flying over the surface.
