The distribution of Bufo poweri in southern Africa

Abstract

Bufo poweri is shown to be distinguishable from B. garmani on the basis of different male advertisement calls. A survey of published and unpublished sonagrams, and data summarizing sonagrams of calls, was used to determine the geographic ranges of the two species. B. garmani is found in the north and east, and B. poweri in the south and west of Africa. Further fieldwork is required at the boundary between the two species.
