Red-shouldered hawks seem to have increased their range over my lifetime. This is an observation and may or may not be true. They are most often seen in riparian areas. They are very vocal and their call is loud.
They are a member of the Buteo family of raptors and their wings appear a bit stubby, apparently to help them fly through trees and brush while pursuing their prey.
Here are a couple of my best red-shouldered hawk photos. These pictures are of the same hawk, that flew to a pond where I was standing with camera in hand.
