The Desert Museum had a free-flying raptor presentation where they let the birds fly around over the spectators and land on the cacti and other object around. It's pretty cool, although it was very crowded so I could only get and occasional glimpse of the birds. Here's one who landed on a tall cactus--I don't remember what species this is.
