Detailed description of bird: Size - Smaller than a Red-tailed Hawk, but larger than a crow. Field guides indicate 17" L & 40" W.
Color - Brown head and back. Throat & breast brown, flanks & belly were streaked with brown & kind of white, or off-white. Vent area was white. Tail was black with 4-5 thin white stripes. Wings were mottled with white, but not as distinctively as the field guides show. There wasn't any color (red or rust) on the scapulars or shoulder indicating that it wasn't an adult. There was a translucent pale crescent across wing tips.
Flight - The flight was more rapid &direct than a Red-tail. The translucent crescent was very visible in flight. When it flew straight away it flew accipiter-like with rapid wing beats & then a short glide.
Song or call & method of delivery: None
Behavior: The hawk flew from one tree to another & landed deep in tree branches rather than on top.
Habitat: Trees near water. Open area near Powell Slough (a marshy area) on the east side of Utah Lake.
Similar species and
how were they eliminated:
Red Tail juvenile - This bird had distinctive tail bands, not thin bands like a Red Tail.
Broad-winged Hawk - Tail banding different, & this hawk was larger than a Broad-winged. Not here during winter either.
Previous experience with this & similar species: Previous experience with this and similar species: I have seen Red-tailed hawk five or six times before in this state and am familiar with both the adult & the juvenile. This was definitely a juvenile Red-shouldered Hawk.
