Oakland: 2.2.1, Harley is the young female and the only one I could find the name and she lives with 2 males. There's an elderly pair as well and I know one's a male but I could not find out the other hyena's gender. Harley and her exhibit-mates are from Berkeley.
Phoenix: 2.0.0, Huckleberry and Cahli
I tried to focus on AZA-accredited zoos but there's a few zoos I mentioned that aren't accredited. I'm probably missing some places but my brain hurts
Also Toronto has hyenas but they're in Canada.
