Birds of Prey at the Sonoran Desert Museum near Tucson, AZ.

They have a program where the birds are in free flight.  The trainers put pieces of meat on dead tree branches on either side of the spectators.  The birds fly very close over the spectators.  The birds respond to hand signals by the trainers.  The humming birds are in an aviary, but it is still very difficult to photograph them because of the their very rapid movements.
