Animals that are only found in one American zoo or aquarium

Maryland zoo and toledo zoo both have white breasted cormorants.

 

Taganyika Wildlife Park keeps a group slightly larger than Bronx's.

I believe Memphis is the only place with yellow-casqued hornbill.

 

Apologies, should have written within the US

 

Yes, I got your meaning. But TWP is within the US: Tanganyika Wildlife Park
Witchita, Kansas.

 

That animal is dead....

 

I know this question is off topic but since Ethiopia has a export ban on their wildlife, how will San Diego zoo get geladas in the future?

 

From Europe. There are quite a lot of them in the European zoos.

 

From Rheine (Zoo), IIRC?

 

Coolio the northern elephant seal, Pittsburgh

 

I think Omaha might still have them?

Edit: maybe not if TWP does, as I think there is supposed to only be one other holder.

 

Omaha does not, but TWP's individuals were imported from Howletts. Not sure where Omaha's went.

 

And Bronx's group is getting on in age and hasn't had a baby in a long time. Will be interesting to see what the zoo is planning on replacing them with eventually. Maybe proboscis monkeys

 

One can only hope...

They will probably be replaced either by Francois' or silvery langur, the two species with AZA breeding programs. Unless they decide to go against the grain and import a different species from somewhere else (a new group of Javans, for instance).

 

Do any zoos have brocket deer in the U.S.A?

 

Yes. Gladys Porter, Bergen County, Phoenix, and Tanganyika Wildlife Park all have them.

 

According to the Milwaukee County Zoo, they are the only institution in North American to display Ornate flying snakes.

 

There are a decent amount of zoos that have southern sea otters, but which zoos have northern sea otters (other than Pittsburgh, and not Seaworld or an aquarium)

 

I mentioned this once and was told Toledo has them as well

 

Most likely Francois', as silvery is already exhibited elsewhere in the building. Personally, though, I hope the exhibit is renovated a bit first. It isn't bad, but the climbing structures are all on the same level, so there's little variation in height. What are some other interesting species that could go in there?

Animal World and Snake Farm Zoo has this species, and I believe they're in a few other institutions as well- California Academy of Science perhaps?

Minnesota Zoo has I believe three individuals. Not sure why you made the unnecessary exclusion of aquariums, but the New York Aquarium might have one still, and I believe the Georgia Aquarium has one as well.
