What I like about the pair bonding of raptors is the uncomplicated distinction between the pair roles in creating territory, defending it and raising young. The male hunts while the female nests, and when there is a threat, the male defends. Here is the Riverside female issuing her territorial E-Chuk! call as the male comes out and then attacks some unseen intruder (my guess is the plucky Osprey that's been making trips from CP to the West Side).
While the Morningside Kestrels follow the same pattern. It is the female who call the male to mate, and he who hunts for that priviledge. Here is the female coming out of their nesting cavity to receive her prize!
Cant wait for those little chickies!!!
