This is as juvenile Red-shouldered Hawk. The folded primary tips stop about 2 inches shy of the tip of the tail. On a Red-tail the primaries would be even with the tail end. A Cooper's primary tips stop at the base of the tail when folded. The cere is still gray/ blue--that waxy tissue around the nostrils, unlike the horny beak itself. Adult raptors usually have a yellow cere. I saw my first 'shoulder in Oregon at Eckman Lake,(Waldport) in 2004. While it was flying l thought it was a Cooper's--the wings are so short and the tail so long compared to other local buteos. The wing load is high so Redshoulders have an Accipter giss in motion. I believe half or more of the Redshouldered Hawk detections l've made north of Polk County were in November. And with one notable exception , all first year birds.
