I like the fact that it is possible for some of the birds of prey to fly over the heads of visitors. Plus, seeing harpy eagles is always a thrill because barely any zoos have them in North America.
Let me see if I can remember.
African Crowned Eagle
Milky Eagle Owl
Andean Condors
Harpy Eagle
King Vulture
Bataleur Eagle
I think that there is one more, but I can't remember what it is.
