Jane and I see loads of Swainson's Hawks on our yearly trek to North
Dakota to visit her family. The easiest field mark on the Swainson's
over all other North American buteos is the wing shape. If you look at
Broad-wings or Red-tails, they have large bulging wings with blunt or
rounded looking tips. The Swainson's has a sharp scimitar shaped wing
with very pointy primary projection. Peterson doesn't really show this
but Pete Dunne said this is the easiest field mark for picking one out
of a crowd.
