Patterns of nest placement of lappet faced vulture (<i>Torgos tracheliotos</i>) in Lochinvar National Park, Kafue Flats, Zambia

Abstract

This study assessed the nesting patterns oflappet faced vulture inLochinvar National Park, on the Kafue flats,Zambia. Road drives and foot patrols were used to identify and take GPS coordinates of lappet faced vulture nests. The main objectives of the study were: 1) to obtain basic breeding information of lappet-faced vulture in Lochinvar National Park and the Kafue Flats in general, 2) to determine size of the breeding population in the National Park, 3) todocument distribution of the nesting sites, 4) tofacilitate development of a monitoring programme that would secure the nesting sites from human disturbance, and 5) to determine availability of suitable nesting sites and major threats that may interfere with breeding. Tree species on which nests were found were identified and height of nest above ground was estimated. A total of 22 nests were recorded with 5 (23%) being lappet faced vulture nests on seven species of trees. The mean height for nest placamenet was10 mabove ground. Host tree physiognomy, size and height were important characteristics in nest placement. Large trees of 10mand above are critical in facilitating nest placement and must be protected in identified breeding sites.
