One day Ian was in the barn and a big buzzard swooped down from above and aggressively flew at him. It spooked him a bit. Turns out the buzzard had a nest hidden in the barn and she was defending it. Later, I started seeing two white chicks standing in the barn window, waiting for their mother. Or maybe cooling off as I imagine it gets pretty hot under that tin roof during the day. They are getting quite large and turning black now. The buzzards are of the black vulture variety.
