Mathematical demography of the Cape vulture
The Cape Vulture Gyps coprotheres is one of the world's largest avian scavengers and was once widely distributed in southern Africa, to which it is endemic. It has suffered major changes of fortune in recorded history and has, at least twice, undergone large range contractions and expansions in the …

The influence of vulture restaurants on breeding success and nestling body condition of Gyps vulture populations across southern Africa
Vulture populations in many parts of the world continue to decline owing to numerous threats, such as lack of adequate food sources, poisoning and collisions with power-lines. Worldwide, supplementary feeding sites (hereafter, vulture restaurants) have been used as a conservation tool aimed at …

An investigation into the root of two of the main vulture threats: poisoning and belief-based use of vulture body parts in Southern Kenya
Vultures are crucial scavengers, removing carcasses, and maintaining the healthy and clean environments. However, their populations are rapidly declining. Six of eight Kenyan vulture species are currently listed as ‘Endangered' or ‘Critically Endangered' on the IUCN Red List. Poisoning caused by …

Identifying drivers of Cape vulture (Gyps coprotheres) space use in southern Africa
The decline of worldwide vulture populations due to multiple anthropogenic threats is recognised as one of the most important issues in avian conservation due to the loss of the important ecosystem services that they provide. The Cape vulture (Gyps coprotheres) is endemic to southern Africa and is …

The role of supplementary feeding sites in vulture conservation in South Africa
… Nowhere is it perhaps more popular, than in vulture conservation. Vulture supplementary feeding sites (SFS), also known as vulture restaurants, are specific locations where carcasses and unwanted animal parts are provided for vultures to feed on. This is proposed to be a win-win scenario in …

Black and turkey vulture roost dynamics, marking, morphology and nesting in Virginia
Black vulture (Coragyps atratus) and turkey vulture (Cathartes aura) roosting dynamics were studied at eight roosts near Radford, Virginia. Black vulture numbers at a permanent roost ranged from low monthly means in June 1982 and 1983 to peak monthly means in December 1981 and 1982. Turkey vulture …

An investigation into the decline of the bearded vulture : Gypaetus barbatus in southern Africa
The Bearded Vulture Gypaetus barbatus is a Critically Endangered species in southern Africa whose entire range in the Southern Hemisphere falls within the Maloti-Drakensberg mountains of South Africa and Lesotho, which forms the area of focus for this research. In this thesis I have attempted to …

Exploring the use of GPS-tracking to investigate the diet of African vultures
Vultures are highly mobile scavengers that cover vast distances on their daily foraging trips. Vultures display specific spatial and behavioral patterns when feeding on carcasses, and these behaviors are potentially identifiable in the tracks of geographical positioning system (GPS)- tagged birds. …

Sheep farmers and turkey vultures (Cathartes aura) in the Falkland Islands: from conflict to coexistence
… conflict regarding the lethal control of turkey vultures Cathartes aura by sheep farmers in the Falkland Islands. The conflict escalated after the passage of a government policy limiting the traditional method of vulture management (i.e., shooting). I interviewed half of the sheep farmers on the …

Assessing the anthropogenic threats to vultures in the communal farmlands of Namibia
… control livestock predators is a major threat to vulture populations across Africa. In Namibia, there is now some understanding of poison use on commercial farms, but the situation in the communal farmlands is still poorly understood. Using a series of 36 questions, I interviewed 367 communal …

Home range, habitat use, behavior, and morphology of the Gettysburg vultures
I investigated several aspects of black vulture (<u>Coragyps atratus</u>) and turkey vulture (<u>Cathartes aura</u>) ecology in southcentral Pennsylvania and northern Maryland. Black and turkey vultures did not move randomly over the study area but remained within large (X̅ = 15,993 and 62,953 ha …

Habitat selection of adult bearded vultures Gypaetus barbatus in southern Africa: implications for conservation
The Bearded Vulture, Gypaetus barbatus, was previously distributed across southern and western South Africa, as far south as Cape Town. Today, the entire population in southern Africa is restricted to the Lesotho highlands and the Drakensberg escarpment and nearby mountains in South Africa, where …

Quantifying national abundance changes of raptors across Botswana using repeat road surveys
… trends of many raptor species, especially vultures. Fortuitously, Botswana has over 55,000 km of raptor road transectsurveys originally conducted between 1991-1995. Over two decades later, researchers repeated some of those surveys (c. 21,000 km) in the northern part of Botswana, which …

Space and resource use of Cape Vultures at an isolated colony in the Western Cape: importance of livestock agriculture to this thriving population
Vultures are keystone species providing crucial ecosystem services, yet their numbers have declined globally, including in Africa, due to various threats. Understanding their habitat use and resource needs is vital for conservation. The Cape Vulture (Gyps coprotheres) colony at Potberg in the De …
