Translocated rhinos, Kenya 1984-1995. Overall there was no bias in the sex ratio of calves born to translocated rhinos (22 males, 21 females, 1 unsexed). However, sex ratios of calves born in particular sanctuaries did show a marked, but not consistent bias. For example, male calves exceeded female calves by approximately 2:1 in the Ngulia and Lake Nakuru sanctuaries (6:3 and 9:5 respectively) but the reverse was found for calves born at Lewa Downs (4 males: 8 females).
