Old records being what's on Global Species? That's where I looked and it has them down as
non-subspecies and nominate. Old ZIMS is what I call those records simply because saying the old name might just send a ping to good old Uncle Sam
The original Sun Bear population into the 90's were all nominate (there never have been any actual non-subspecies Sun Bears in the US), then in the 90's we switched to
euryspilus. Neither population has done particularly well and most animals have never bred. All are getting pretty old now, but any nominate would be particularly old. The animals listed in 2010 for Atlanta are the same bears still there, so if old records list nominate then presumably they'd be very old nominate bears (though they definitely didn't look it). However, as you said, Columbus has
euryspilus not nominate and the Atlanta came from there according to the
article about their arrival. Possible Columbus had nominate and switched to Bornean? That's what I'm curious about. I've definitely seen both subspecies anyhow so it's not a huge issue for me, I'm just curious about the status of this species in US zoos. We do not have many left.
