Habitat associations of birds at Mara Naboisho Conservancy, Kenya

Abstract

Habitat associations of birds were quantified through fixed-radius timed bird counts at Mara Naboisho Conservancy within the Greater Mara Region, Kenya. We conducted 73 timed counts in four distinct habitats (riparian, woodland, rocky outcrop and plains) in both dry and wet seasons. During this survey, we observed 188 species of birds of which 140 were recorded during the timed counts. The riparian zone had the highest species richness, more than three times that of the plains. The woodlands and rocky outcrops had similar species richness. The mean number of species seen per count was higher in the riparian zone compared with the other three habitats. Bird species composition in the riparian zone and the plains were distinct from each other and from the woodlands and rocky outcrops, although they overlapped significantly in the last two mentioned habitats. The possible conservation implication of an increasing and/or immigrant elephant population and its likely effect on the vegetation is discussed in relation to bird community composition.
