Nope. In fact the barn swallows that make their nest in the barn alley just can't understand I'm not going to hurt them, they fly out any time I go in. I really have no choice but to go near the nest since it is on the floor joist right in front of the stall coop, not 6 ' away. I've never gone real close to the tree swallows in the birdhouse on the post out by the pond though. Don't know if they would dive bomb me as a threat.
