I once left the door to the attic of my garage open for a day no big deal so I closed the door the next day. Probably 3 days later I go up there AND THERE WAS A RED TAILED HAWK IN MY ATTIC! I just opened the attack double door and it flew away. But it was flying around like crazy. I dont know why it went in, in the first place. Maybe for the rats?
maybe, don't know hawks but the little wrens are always on the look out for a site for the nest that they think will be safe against cats and other critters, not to afraid of humans for some strange reason
