Could this be a red shouldered Hawk?
Juvenile being harassed by four crows & a bluebird for about 1/2 hr.

I'm hoping someone can identify based on the markings on the tail.
The Red-shouldered Hawk (Buteo lineatus) is a medium-sized hawk. Its breeding range spans eastern North America and along the coast of California and northern to northeastern-central Mexico. Red-shouldered Hawks are permanent residents throughout most of their range, though northern birds do migrate, mostly to central Mexico. The main conservation threat to the widespread species is deforestation.
