Swainson's Hawk

I disagree Katie-this is definitely a Swainson's Hawk, Buteo Swainsoni.

I think this bird is a red tailed hawk. Here is some information.

Red tailed hawk - Búteo jamaicénsis - a well known and common buteo; nests in woodlands, feeds in open country. The uniformly colored tail of the adult ----- reddish above, light pink beneath ------ and the dark belly band are the best field marks. The tail of the immature is finely barred. Body is heavier than other buteos', plumage extremely variable. Flying head on, light wrist area gives impression of a pair of "headlights." Often perches on poles or tree tops. Rarely hovers. Red tailed hawks prey on rabbits and rodents. Call is a high scream, often imitated by jays.
