Vulture Flipping - the local sport of Peregrine Falcons. I'd like to say that no Vultures were injured during these sporting events but from the amount of feather floating down I cannot, in good conscious make that statement.
Flipping is not exclusive to the Vultures. Give them a Red-tailed Hawk that wanders too close and a flip is guaranteed to happen.
Dee grabs the wingtip, the Vulture flips and Dee rides the flip in a fast crack-the-whip ride. This is Dee's favorite method.
BJ favorite sport is to grab their talons and flip the Vulture.
All like to surf on the Vulture's backs.
A fledgling flies with a Vulture. She didn't quite have the nerve for a close interaction but that time will come.
When not in the mood for a wild ride all will quietly escort them out of the territory. Rose and Boone tend to do this as a team effort.
