The breeding success of the nests of 60 African White-backed Vultures Gyps africanus, nine Black-chested Snake Eagles Circaetus pectoralis and 12 Secretarybirds Sagittarius serpentarius was monitored for three years, during a seven-year population dynamics study on raptors in the Kgalagadi Transfrontier Park (KTP). We also report on nest site selection, timing of breeding, population fluctuations and anthropogenic factors that affect mortality. On average, African White-backed Vultures produced… Expand
Changes in nesting numbers and breeding success of African White-backed Vulture Gyps africanus in north-central Botswana
Summary African White-backed Vultures were recently uplisted to ‘Critically Endangered’ by IUCN due to declines across their range. Poisoning is widely accepted as the major reason for theseExpand
Nesting status of African White-backed Vultures Gyps africanus in the Masai Mara National Reserve, Kenya
Vulture populations have declined globally as well as regionally within Africa. Little is known about the status of the African White-backed Vulture Gyps africanus in Kenya, but ongoing studiesExpand
Population estimates of three vulture species in Kruger National Park, South Africa
Vultures are globally threatened, yet reliable population data on these birds are few, thus measuring their response to change is difficult. Kruger National Park (KNP) in South Africa is an importantExpand
An Assessment of Tree Availability as a Possible Cause of Population Declines in Scavenging Raptors
TLDR
It is concluded that on a landscape scale, tree availability is not a limiting factor for any of the species considered here (White-backed, Lappet-faced, White-headed vultures, and Tawny eagles). Expand
Birds of a Feather: Quantitative Assessments of the Diversity and Levels of Threat to Birds Used in African Traditional Medicine
TLDR
The richness of bird use for traditional medicines across Africa is reviewed, showing that 24% of traded bird species are very common and locally abundant in several habitats over a large geographic area, and the order with the highest proportion of rare species was the Bucerotiformes (hornbills). Expand
Dispersal dynamics of juvenile Secretarybirds Sagittarius serpentarius in southern Africa
TLDR
The wide-ranging behaviour of juvenile Secretarybirds exposes them to a diverse range of threats, and a better understanding of their movements will aid the development of appropriate conservation strategies for this terrestrial raptor. Expand
Risks to Birds Traded for African Traditional Medicine: A Quantitative Assessment
TLDR
Based on cluster analyses for species groups of similar risk, vultures, hornbills, and other large avifauna, such as bustards, are most threatened by selective harvesting and should be prioritised for conservation action. Expand
Raptor population trends in northern Botswana: A re-survey of road transects after 20 years
Abstract Across Africa, many raptor species, especially vultures, are in steep decline. Botswana is regionally important for numerous raptor species including vultures, but recent population trendsExpand
