Bird distribution dynamics 1 - Hamerkop <i>Scopus umbretta</i> in South Africa, Lesotho and Swaziland

Abstract

A full investigation of the abundance of the Hamerkop should be undertaken, as well as trends in its abundance. We recommend an assessment of the impact of Egyptian Geese on nest sites. We also need to examine how dependent Hamerkops are on frogs of the genus Xenopus as a food resource, and to understand how the distribution and abundance of these frogs has been modified. Finally, a consideration of the full spectrum of threats faced by the Hamerskop is needed.
