DESCRIPTION OF THE BIRD(s)
Medium sized raptor with all white breast and underside. Very slender looking when perched. Light morph. Dark mustache type markings on tan colored face and head. Dark eye strip. Tan marking on shoulder extending part way onto breast. Somewhat pointed wing tips with straight leading edges. White band on tail. Yellow legs with small feet/talons.


BEHAVIOR OF THE BIRD(s)
This bird was perched in the upper third of a cottonwood snag located about 200 meters from our position. There were two observers... Fred Forssell and Regan Plumb. The bird was mostly stationary, but occasionally would leap from one branch to another. It flew from on snag to another about 40 meters away. After about 10 minutes, it flew off and out of sight.

This bird was in the area from 9/2/19 throught 9/5/19. On 9/6/19 a front moved in and it rained from 6 am until late that night. The raptor has not been seen since.

Unfortunately a lightly written report with no comparative analysis to similar species, particularly with Red-shouldered Hawk (Buteo lineatus). The excellent photos were very helpful in reviewing this record, though have to be honest, a few marks concern me – speckled scapulars and upper wing coverts, apparent light bases of outer primaries (upper and lower), and barring on underside of secondaries (all plumage features of a Red-shouldered). This said, the “jizz” of this bird is good for Broad-winged Hawk (B. platypterus) – short tail, chunky build, big head, broad wing base, and pointed wing tips (also mentioned by observer). Plumage wise, the clean white belly, little streaking of the central breast, and relatively even pale/dark tail banding also point to this being a good identification.
