The staff at Germany's Krefeld Zoo say that a tightrope walking gorilla's attempts to impress the ladies appears to have paid off. Kidogo, the gorilla, has been accepted as a mate by both of the females in his enclosure since starting his high wire act done on ropes stretched between trees. A spokesperson for the zoo said, "They can't seem to get enough of his company - his high wire hijinks really do the trick." Zoo keepers believe the inspiration for the gorilla's high wire stunts may be human visitors. The spokesperson continued, "We have observed he really seems to prefer walking upright like a human, we think he might be copying the visitors." The tightrope had been intended for him to hang from but keepers were amazed when he climbed up and began walking on it instead.
