 This ability may be widespread among echolocating bats, but in this species that faculty is well documented Indeed, pale spear-nosed bats show an unusually complex vocal repertoire, with up to 20 different calls, similar to that of many non-human primates.In addition to vocal communication, males also scent-mark their roosting sites using their throat glands, and both sexes are able to recognise specific males by their scent alone.Mating occurs primarily within the harem groups, although females may sometimes be chased by non-harem males before copulation.
