Abstract

A histological study of reproduction in Egyptian free-tailed bats (Tadarida aegyptiaca) from the Eastern Cape Province of South Africa (c. 33'S) showed that females were seasonally monoestrous. Copulation, ovulation and fertilization occurred in August, at the end of winter, and births in December, after a four-month pregnancy. These results are compared with those of other molossid bats from lower latitudes in Africa. We conclude that the monoestrous habit of the Egyptian free-tailed bat at 33? S may be due to its relatively long pregnancy, and to the short summer period during which minimum temperatures are high enough to ensure an abundance of nocturnal flying insects.
