I've observed Cooper's Hawks in the past with their white undertail coverts "fluffed" (for lack of a better word) - almost appearing to have a fully white rump. I know I read somewhere (not sure where though...) that they do this either as a breeding display, or as a sign of defense or alarm.

We live in a mixed forest and open rural area. Harriers in migration will show up overhead, and sometimes low to the ground near the edges of the woods.

A few years ago I was in the field, and on 2 occasions in late winter/early spring, I flushed a harrier out of a small grassy patch in a small opening in thick forest a little before sunrise. I assumed roosting there, maybe in migration.
