THE STATUS OF AFRICAN VULTURES

In 2015, the IUCN Conservation Status of several vulture species were ‘uplisted’ based on their rate of decline. African vultures are facing several threats, making their conservation a formidable task.

Vultures form an important ecological component of our natural environment, cleaning up dead carcasses and decreasing the spread of some diseases. The relationship between vultures and people is also a venerable one – vultures played roles in some early societies, including the Egyptian and the Hindu societies; vultures continue to be used as symbols or metaphors in modern societies; and vulture body parts are used in muthi.

Today, vultures face an unprecedented onslaught from human activities. They have to cope with electrocutions and collisions with electrical structures, poisonings, land-use changes, a decrease in food availability and exposure to toxicity through veterinary drugs, to list just a few of some of the challenges facing vultures today.

Vultures, positioned at the top of the food chain, are an indicator of the health of the environment below them – and dependent for their survival on a healthy environment. As such the work of the Vulture Conservation Programme (“VulPro”) is intended and expected to favourably impact on many other aspects of the environment – beyond vultures.

While a single poisoned elephant can kill hundreds of vultures, wiping out an entire colony or local population, power line electrocutions and collisions are the most profuse threats to vultures in South Africa. The power line grid is expansive and often structures are out of date and unsafe for the large birds to perch on. 

Poisoning incidents seem to be on the rise, or at least are much more regularly reported. Poisonings occur from a few means – poachers lace elephant or rhino carcasses to intentionally kill vultures and as scavengers, vultures inevitably ingest any poison implemented to kill other animals (either ‘problem’ animals like jackals or leopards) or prized animals targeted by poachers. 

Superstitious beliefs are prominent, creating a demand for vulture parts, especially the head (brains, eyes) and feet, in the establishment of luck and forecasting the outcomes of events like soccer matches and the national lotto.

As humans have expanded over the South African landscape, carcasses from natural deaths are sparse, prompting the creation of over 250 vulture restaurants over Southern Africa. These sites provide food specifically for vulture populations mostly from pig and cattle farm mortalities. These sites are strictly managed as some Non-steroidal anti-inflammatory drugs (NSAIDs) used on cattle can be, even in small amounts, lethal to vultures. Diclofenac in particular (Voltaren for people) caused the deaths of millions of vultures on the Indian Subcontinent in the early 2000’s.

Gyps africanus was first described by Salvadori in 1865 in the raptor family of Accipitridae.

Once the most common and widespread of the vulture species on the continent of Africa, the White-backed Vulture population has declined extremely rapidly, by over 90% throughout its range.

All threats and fatal incidents such as persecution, poisoning, habitat loss, reduced and contaminated food and harvesting for cultural practices, are compounded due to the gregarious nature of this species.

Electrocution and collisions with electrical infrastructure pose significant threats of injury and mortality, made progressively worse by recorded nest sites on power line pylons.

African White-backed Vultures are more vulnerable to anthropogenic disturbance, nest harvesting and capture as they are arboreal nesters and social roosters.

Bearded Vulture

Gypaetus barbatus

Gypaetus barbatus, belonging to the Accipitridae family of Aves, was first described as Vultur barbatus by Carl Linnaeus in 1758.

The misnamed Lammergeier is primarily a bone-eating vulture inhabiting remote mountainous areas. This widely-ranging species is restricted to the Maloti-Drakensberg region of South Africa where it is severely under threat due to collisions with power lines and wind turbines.

Other major threats include non-targeted poisoning, anthropogenic disturbance of nesting sites, habitat degradation and inadequate food availability contributing to a negative population trend.
