The Dallas World Aquarium is an excellent aviary with a few fish located in Dallas. It basically has the largest concentration of South American things that isn't located in South America. This being said, I would like to see such things. I don't know how many people have been to it, but if anyone can help with rare things, I'd appreciate it. I will contribute what I know: The aquarium has five eagle species. These are black hawk eagle, black and white hawk eagle (only specimen in captivity), Guianan crested eagle, harpy eagle, and ornate hawk eagle. From what I've read about the aquarium (website, history book, forums) they are not all on display at once. Some rotate between their exhibits and the behind the scenes (bts) breeding aviary. Most of the aquarium's hummingbirds are also in Mundo Maya. Crested and golden headed quetzals are both here also. Speaking of quetzals: The DWA has the only resplendent quetzals in the USA. They have four that were imported from Mexico. One male, three females (1.3? Did I do that right?). Two were from ZooMAT, two from a private breeder. They are in an extremely lushly planted habitat, with a real dirt floor, and on a rain system. They are camera monitored 24/7. The DWA has seen potential nesting behavior recently. Source: the second time I went to the aquarium I went with a friend. We asked lots of staff about the resplendent quetzals. When we were about to give up hope, we asked one more staff member. And one very special millionaire was standing next to that staff member: Daryl Richardson, the owner (yes, owner) of the aquarium. He was about to explain how they were off exhibit, and then said "Never mind, I'll just show you." He took us through a door near the jaguar exhibit (hate that... It is sad) and through a staff cafeteria, and up some stairs. Once up the stairs, there was a large aviary for a breeding colony of one insanely rare bird: Guianan cock of the rock. I counted at least five. In the center of the room was a large cylindrical tank with at least one leafy sea dragon. There were a few in the walls with freshwater stingrays. There were desks and offices in adjoining rooms. Up more stairs, opposite a balcony overlooking the earlier mentioned tanks, were lots of aviaries. The second one held the quetzals. I'll upload a picture later (warning: terrible quality) that has the owner and a female in it. He went over and shook a branch to make the male quetzal fly (which was an amazing experience). My day was made a lot better by that. Horned guans are behind the scenes. All (or most) of the manakins are in an Orinoco exhibit called The Lek. Brown throated three toed sloth (something rare that isn't a bird) is hard to miss in its Orinoco exhibit. Shoebill stork and Asian Arowana are in the "Borneo" entrance exhibit, as well as Pesquet's parrots. Six species of toucans (toco, Swainson's, red breasted, Ariel, plate billed mountain, and one other) are distributed through the top floor of Orinoco, with lots of aracaris and toucanets Red howler monkeys are easy to miss in Orinoco. Look up and around. I will list more later.
