Passage of weak front aroung 11 am on Sunday Oct.3 brought a nice mixed kettle of hawks over my house in Darnestown, Montgomery Co MD:
2 broad-winged
2 sharp-shinned (repeatedly diving on the broadwings)
3 red-shouldered hawks
1 red-tailed

a little later, a harrier, several turkey vultures and black vultures brought the species total to 7 species.
