We have a hawk living in the treetops. I thought it was a red tail hawk, but doing some research and listening to their call I think it is actually a red shouldered hawk. I haven't caught it with my camera yet, hopefully soon.
Red shouldered hawk: A loud, screaming "kee yar" dropping in pitch, typically uttered 2-4 times. Red-shouldered hawks are quite vocal (blue jays frequently mimic their call), especially during spring courtship.
Red tail hawk: Often described as a scream, resembles a long, wheezy "kkeeeeer." Used on television, regularly dubbed over as the sound of an eagle or vulture.
What bird website you can listen to the different voices. Here is a photo of a Red Shouldered Hawk from Wikipedia.
Beautiful bird, I love hearing it call... Kee yar kee yar kee yar kee yar... be well... Tj.
