OVERLOOKED UNITS OF COMPARATIVE AND CONSERVATION BIOLOGY - A CASE-STUDY OF A SMALL AFRICAN BUSTARD, THE BLACK KORHAAN EUPODOTIS-AFRA

Two small southern African bustards, the Black-winged Korhaan Eupodoti s afra afra and the White-winged Korhaan E. a. afraoides, have long be en treated as conspecific. However, differences in their habitats, plu mage, morphometrics, displays and vocalizations of males, mitochondria l DNA restriction fragment length polymorphisms and, possibly, social systems strongly suggest that they are distinct species.
