I haven’t read all 700+ replies, so maybe it’s already been asked and answered, but;
Why are you guys so excited about the barn swallows?
The barn I’m in now had a pair when I moved in. They were pretty cute and raised their babies. The whole family would line up every night on a rafter in the barn and watch me do night chores, even long after the babies could have taken care of themselves.
Year two a (I believe different) pair came back. They were extremely aggressive and would dive bomb me and the horses in the barn. It was so bad the horses didn’t want to go inside.
This year, they came back again, but I said ‘no more’ and knocked down all of their nesting material as they started to build because one of them again started to harass and dive bomb me. It went so far as to follow me into the tack room.
Do I just have the nasty thug barn swallows here? Why are mine so mean?
