Which zoos in the Usa have okapi in mixed exhibits, and which what species, I guess, mostly duikers ? I know, the Us-zoo change their combinations from time, so I think, San Diego WAP does still have them with yellow-backed duikers, so most okapi holders do,I belive ? I'm not sure about L.A and San Diego Zoo if both keep them together with Black Duikers ? Any other duikers, small antelopes or other species kept together with Okapi ? In europe,most common combo is Okapi/red Duiker ( of course not many duiker species have left)and I think, now with some birds at Rotterdam and Doue La Fontaine.
