One of the most distinguishing features of this species, male or female, is a white rump patch. While that can't be seen in the photo, the "ink dipped wings" of the male are visible (at least the right one
). They hunt differently than either the Buteos or the Accipiters as well. They work the open fields in low sweeping motions, rather than circling or hovering at heights like a Red-tailed does, or streaking in on their prey "from out of no where" like a "Sharpie" or Cooper's does.
