Joe,
   Mississsippi Kites should be in South America now, or perhaps just started on the way north.  Harrier seems more likely for gray hawks at this time of year.

Since they had no windows in the wing and were gray, I decided it was time to get out the books -- my best guess is that I saw two Mississippi Kites (a first for me but that makes the call all the more questionable).
