Is that a raptor? At least it's a handsome bird. Have you ever seen a turkey vulture? [pinterest.com]
It's a magpie and during mating season they'll swoop and attack the head of anyone who gets too near to their tree and people are frequently injured by them. Last year I had one bounce off my bike helmet because I rode too close. Another good reason for wearing a helmet.
