First okapi born in captivity, in Antwerp
This photograph was taken at 5 years of age with the giraffe and okapi caretaker at the Antwerp zoo. I believe he was one of the native men (who assisted in the live trapping) that came from the Congo with one of the transports of central African wildlife. I don't have his identity, though, so I don't know.
Being naturally shy and quiet creatures, transporting live okapis out of their environment into zoos and wildlife parks was far too stressful for them to survive the trip, even when they had proper food and care. So, for a long time, only taxidermied specimens were seen outside of the Congo region. The first okapi to survive the trip lived at the Antwerp zoo, so it's only fitting that the first successful breeding of okapis would happen there, as well.
