I know that species management in the USA isn't done by subspecies and all of the chimps are presumably hybridized, but are there any known pure chimps of any subspecies in the USA?
I wonder because I've recently read about how Western chimpanzees are behaviorally different from their Eastern and Central counterparts in many ways and was curious if those behavioral differences were purely 'cultural' practices or if they could interfere with troop dynamics in zoos.
There are a few chimps in my local zoo who definitely have a stereotypical "Western chimp" look about them. One of them is the highest-ranking male, Kasoje. I saw that he was born in the Little Rock Zoo to two wild-born parents and the Little Rock Zoo website lists "Western Chimpanzee" among the animals they exhibit. Do we think any of those chimps are legit Western chimpanzees (and do we know where Kasoje's parents, Richard and Judy, were captured from?) or is it just like zoos labeling generic tigers as Bengal?
