アカオノスリ Buteo jamaicensis

Most common roadside raptor across much of North America. Often perches atop telephone poles, light posts, and edges of trees. Incredible variation in plumages, including less common dark morphs and various regional differences. Eastern adults have brilliant reddish-orange tail and pale underparts with obvious band of dark marks across belly. Western birds are typically darker. Immatures do not have a red tail.
