List of rarest species in US?

[Okapipako]

I'm aware there's a thread on this topic already, but it's been roughly 6 years since the last post in it and I have a more specific request.

Obviously this information isn't readily available publicly at the moment, but I know some members keep and have kept tabs on these things to an extent. I was wondering if anyone had on hand information on which species (if possible subspecies as well) are kept in only 10 or fewer American zoos? If it's less trouble I'm most interested in mammals. Information doesn't have to be precisely up to date but the more recent the better.

This is for the purpose of planning and prioritizing zoo-based trips, although rare species aren't the only factor I'm considering but are a significant one. If possible something like the post by Dassie rat in this thread would be appreciated, as it's helped me do the same for eventual trips to Europe: Rare and new at the zoos of europe

[Okapipako]

Thank you so much! Extremely helpful.

I'm still interested in species found in more than one but still uncommon if anyone has this information.

 

[birdsandbats]

Kangaroo Island Kangaroo Macropus fuliginosus fuliginosus - Gladys Porter Zoo

Apparently Brookfield keeps this subspecies as well.

10 or fewer still is a pretty big category. A few that come to mind offhand:

Giant Panda (San Diego, Atlanta, National, Calgary)
Tasmanian Devil
Hawaiian Monk Seal (Minnesota, Wakiki Aquarium, I think another one or two in Hawaii)
Giant Otter
Knobbed Hornbill
Red-footed Booby (Monterey Bay Aquarium, a couple in Hawaii)

 

[jayjds2]

Yellow-Casqued Hornbill Ceratogymna elata - Memphis Zoo

Kept by at least one other zoo.

Guatemalan Mantled Howler Monkey Alouatta palliata - Gladys Porter Zoo

Pigra, not palliata.

Side-Striped Jackal Canis adustus - Boulder Ridge Wild Animal Park

Kept by at least one other zoo.

Pacific White-Sided Dolphin Lagenorhynchus obliquidens - Shedd Aquarium

Kept by two other zoos.

Apparently Brookfield keeps this subspecies as well.

Brookfield keeps melanops and non-ssp individuals.

Does anyone know of any animals that need to be added to this list?

 

[TinoPup]

Here's two threads that have both been active within the last month.

Animals kept at only one zoo outside of their native range

Animals that are only found in one American zoo or aquarium

Catoctin has booted macaques. SeaWorld (San Diego, I think it was?) has a harp seal and a ringed seal, both seem to permanently live there but both species can occasionally been found at other institutions while animals are being rehabbed.

Thanks, must have missed those when searching for similar threads.

Giant Panda (San Diego, Atlanta, National, Calgary)
Tasmanian Devil
Hawaiian Monk Seal (Minnesota, Wakiki Aquarium, I think another one or two in Hawaii)
Giant Otter
Knobbed Hornbill
Red-footed Booby (Monterey Bay Aquarium, a couple in Hawaii)

Memphis Zoo also has giant pandas.

 

[birdsandbats]

Northern Tuatara (St. Louis, Toledo, Dallas)

That's the only one that comes to mind right now. I will probably think of more later.

 

[Kakapo]

I'm aware there's a thread on this topic already, but it's been roughly 6 years since the last post in it and I have a more specific request.

The last post is from... Yesterday.

Animals that are only found in one American zoo or aquarium

 

[Okapipako]

That wasn't the thread I was referring to. I had missed that and one other thread, both of which TinoPup had already linked in this thread.

Kept by at least one other zoo.

@jayjds2 what is that other zoo??

 

[drill]

No Gray's crowned guenons. I don't think Dallas Aquarium has other quetzal species besides for Golden-headed.

 

[Snowleopardqueen]

Toledo, fort wayne, and columbus zoo all have tasmanian devils now

 

[15399]

Does any zoo besides St. Louis have horned guans?
