Okapis on NPR

There is a brief report on the radio program Living on Earth regarding okapis. "Radio Deutsche Welle's Rupert Cook traveled to the Congo in search of the okapi and to find out about conservation efforts." You can read the transcript or listen to the audio here.
(I'm uncertain, though, why they say that European colonists called them the "African unicorn." There are stories of a "unicorn" in Africa, but I don't recall any folkloric connection to the okapi. If anyone can provide a citation for such, I'd be interested...)
