From a friend that would know:
It's a red-tailed hawk (imm), hatched this year (HY). Immatures don't have the "red tail" of the adults. Note the fine barring on the tail which would be wider in red-shouldered (both adult and immature). The breast is clear not reddish, or finely barred, as in adult red-shouldered, or streaked as in immature red-shouldered. The bird is chunky, or heavier bodied than red-shouldered.
