A Study of Leaf-Nosed Bats (Hipposideros caffer and Rhinolophus landeri) in a Cave in Northern Nigeria

Two species of leaf-nosed bats were netted as they emerged from their roosting cave at dusk. Collecting was repeated four times in 1966 and twice in 1967. Color of pelage, age, and reproductive condition of the bats were noted. From these data I conclude that the bats copulate late in the year, undergo a brief period of delayed implantation, give birth about April, and molt between May and July. The natural hair color of the adult is gray but quickly changes to reddish gold. Association between the breeding cycle and climate of the region is suggested.
