This hawk, maybe a Cooper's Hawk, visits near the bird feeders, regularly. When they see or hear him, the small birds, mostly finches, take off.
The other day, this little house finch flew into the patio door and knocked himself silly. The hawk swooped in and landed on the birdhouse on the patio table. He left right away when he spotted Bob.
He came back, frequently, but the house finch recovered; so there was no snack for him. If you know what type of hawk this is, please let me know.
