Rare Animals in US AZA Facilities

Just to remind everyone, the OP said that including non-AZA is OK:


So Sika and melanistic leopards are pretty common (Amur melanistic is still rare).

Yes, but sometimes people ask specifically about AZA.

Deer in general are pretty rare in AZA and immensely common outside of it. There are places with hundreds of fallow, a few in the 500+ range. Walk-through zoos tend to stick to the main three (fallow, white-tail, sika). The other species tend to almost always be in safari areas, with Pere david's and axis being 4th and 5th in numbers overall and the most common of the species found nearly exclusively in those. Mule deer are 6th in numbers and are the only other species found predominantly found in walk-throughs, the are none east of the Missouri and they aren't present in Texas facilities.
 
Saint Louis Zoo I believe is the only US facility to have horned guans on display to the public.
Are they a species that will be kept (and bred?) long-term?

Parakeet Auklet - Aquarium of the Pacific
Did the North Carolina Zoo have them at one point?

Are these species managed by the AZA?
Vietnamese sika
banded mongoose
spot-necked otter
golden white-eye
bridled white-eye
South-central black rhinoceros
Eurasian wolverine

Correct me if I'm wrong on the holders, but I think this list is probably mostly accurate:
- Madagascar green-pigeon - Riverbanks Zoo and Garden
- dhole - Minnesota Zoo, San Diego Zoo Safari Park, Bronx Zoo, The Wilds, Zoo Miami
- golden takin - San Diego Zoo
- semipalmated sandpiper - New England Aquarium, Smithsonian's National Zoo
- Conant's mushroom-tongue salamander - Toledo Zoo
- Laysan albatross - Monterey Bay Aquarium
- silvertip shark - Georgia Aquarium
- red-bellied lemur - San Francisco Zoo
- brown-mantled tamarin - Jenkinson's Aquarium
- Malagasy pond heron - San Diego Zoo
- red-backed bearded saki - Omaha's Henry Doorly Zoo and Aquarium, Wildlife World Zoo?, Dallas World Aquarium
- Sri Lankan junglefowl - Central Park Zoo, Minnesota Zoo, Bronx Zoo
- Madagascar partridge - Minnesota Zoo, San Diego Zoo, Charles Paddock Zoo
- jeweled chameleon - Bronx Zoo
- Brongersma's pit viper - Bronx Zoo
- Travancore tortoise - Philadelphia Zoo
- one-toed amphiuma* - Philadelphia Zoo, possibly others
- Anderson's salamander* - Philadelphia Zoo
- bare-eyed pigeon - Buttonwood Park Zoo
- great black-backed gull - Toledo Zoo and Aquarium

I actually have meant to ask for a while if black or white variant big cats are still present in the AZA at all? Sounds like black leopards still are. I assume the tigers are gone within AZA by now?
 
Semipalmated Sandpiper, not Semipalmated Plover, which is a completely different species.
Thanks for correcting me. I don't know how I missed that, given that I had thought up away to distinguish the species names. "Semipalmated sandpiper" is alliteration and "scarce" starts with the same letter.
 
Interesting to know. Are these included in any of the current population list threads or anywhere? Last I tried looking I only found an older thread.
Not current, especially for white tiger as they are generic and most of the population lists don't include generic tigers.

I am not too familiar with the population threads but I do not believe there is a jaguar population thread on this site. How I would go about it is searching for black or melanistic jaguar in media and seeing if what facilities have recent uploads, then investigating those facilities further to verify.
 
The update I'm working on will include both :)
That's good to know, I appreciate it in advance. I imagine it sounds very juvenile to express interest in color morphs given their lack of conservation value, but there's a few I'd like to see someday.
