I would be very interested in a list of native species, if it's not to much effort.
Sorry for not getting back to you earlier about this! I've finally compiled a list of El Nispero's native species. This is just going off of memory and a few pictures I have, but should provide a fairly accurate idea of their general collection.
Jaguar
Ocelot
Tayra
Coyote
Grey fox
Northern raccoon
Crab-eating raccoon
Black spider monkey
White-faced capuchin monkey
Geoffroy's tamarin
Central American agouti
Baird's tapir
Great tinamou
Great curassow
Muscovy duck
Black-bellied whistling-duck
Common ground dove
Ruddy ground dove
Blue ground dove
White-tipped dove
Pale-vented pigeon
Scaled pigeon
Band-tailed pigeon
Grey-necked wood rail
Wood stork
Common black hawk
Savanna hawk
White hawk
Short-tailed hawk
Grey-lined hawk
Keel-billed toucan
Yellow-throated toucan
Scarlet macaw
Great green macaw
Blue-and-yellow macaw
Painted parakeet
Blue-headed parrot
Red-lored amazon
Mealy amazon
Yellow-crowned amazon
Northern crested caracara
Collared forest falcon
Pond slider
Green iguana
American crocodile
I've also been able to find pictures of American barn owl, Lowland paca and (probably Panamanian?) Night monkey on google, but I didn't see these three species at the zoo so they are presumably no longer present on-show. Hope this helps!
