Bird Signage in Discovery Center

I saw many of these birds (crowned pigeon, pigeons and doves, mesia, pitta, and mousebird), saw ones not listed here (a couple duck species) and failed to see others (parrot, sunbittern, go-away bird). The missing go-away bird was especially disappointing; they are a rarity in zoos and were one of my favorite birds in Tanzania.

There's definitely some interesting species listed in there. Although I do wish more aviaries in United States zoos would have more information about the bird species in their exhibits. I feel that is one area in which AZA zoos could increase their educational value.

How many collections have Greater sunbittern

Does anyone know if they still keep the Pink Pigeon?
