This is Lyle and Eschu, two of our Drills. The Columbus Zoo acquired drills a few years back in hopes of breeding them and saving the captive population. We have had no such luck, and we are positive the problem is the male. The females can still breed so they are going to Edinburgh hopefully very soon. Lyle's fate has yet to be determined. They are not on exhibit and are being housed in the Gorilla building.
