Found one at last!

I have a list of birds that I hope to blip this summer. This swallow is one of them. I'm just not sure if it is a barn swallow or a tree swallow, so if anyone knows, please tell us. I would look it up, but right now I have to go pick up my little Tuesday evening friend. I have no time left for researching birds, but isn't it a beauty. I was so excited to see it when I went to North Chagrin Reservation today.
