Saw this hawk being pestered by a resident pair of Ravens. Landed on a utility tower with one of the Ravens within 6 feet. I thought it was too small for a Red-tailed Hawk. I have seen Red-shouldered Hawks in this area, but I have also been told it could be a Swainson's Hawk. I included a photo near the Raven for size comparison and the best shots I could get from the backside with the setting sun behind him. Thanks for your help.
