Vultures have an image problem. Seen as ugly and associated with death, they are among the least loved animals in the world.
But conservationists in Africa are trying to change that.
They’ve launched an effort to save endangered vultures by trying to put a dollar figure on their incredible value.
A recent report by the BirdLife International conservation organization estimated that vultures are worth $1.8 billion a year to certain ecosystems in southern Africa, which might surprise anyone not familiar with the clean-up, pest control and anti-poaching work performed by one of the most efficient scavengers on the planet.
The report comes at an important time for Africa’s vultures; six of the 11 species found on the continent are listed as endangered or critically endangered by the International Union for Conservation of Nature, which says vultures are highly threatened in many parts of the world.
In Africa, some species have declined by nearly 90%, according to Fadzai Matsvimbo, an extinction prevention coordinator at BirdLife International.
Conservationists hope the report will make authorities and the public more aware of the positive impact of vultures.
It focused on research in Botswana, Zambia and Zimbabwe and shows how a wake of vultures — the term for a group of feeding vultures — can strip a decomposing carcass in hours, cleaning up ecosystems, reducing the chance of disease spreading and the presence of pests like rats and feral dogs, which has great benefits to communities.
Vultures also have extremely strong stomach acid, don’t get food poisoning and are able to consume and neutralize anthrax, botulism and other bacteria and toxins in carcasses that would kill other animals, removing deadly threats from the environment.
Just this week, more than 50 hippos died from suspected anthrax poisoning in a reserve in Congo.
Conservationists have raised the case of the drastic loss of vultures in India over the last 30 years and how that led to a health crisis.
A study published last year said half a million people died in India because of the spread of bacteria and infections in the absence of vultures.
“From a medical, from a veterinary and from a financial point of view they are extremely important in the environment,” said Alistair Sinclair, general manager of the Vulpro vulture rehabilitation centre in South Africa, which treats sick and injured vultures to be released back into the wild.
“If one had to just consider if the vultures died out and we got increases in foot-and-mouth, for example, the red line district would have to be increased, exports of meat out of South Africa would be curtailed, the whole coal chain process would lose money, the farmers would, as well as South Africa losing forex. So they’re extremely, extremely important.”
Vultures are unique among land vertebrates in that they only feed on carrion — dead animals.
That makes them especially susceptible to poisoning by humans, either intentionally by poachers and others who want rid of them, or by mistake when pests are the target.
Hundreds of vultures can die from a single poisoned carcass.
Vultures are also regularly killed or maimed in collisions with powerlines in Africa.
And they are increasingly being killed for belief-based reasons, said Kerri Wolter, the CEO of the Vulpro rehabilitation centre.
She said because vultures have such outstanding eyesight and instincts when it comes to finding a dead animal that they are viewed by some as being clairvoyant and able to foresee death.
Their body parts, and especially their head, are used in potions or as charms to predict the future.
“We’ve managed to rehabilitate and release just rehab birds not captive-bred birds just on 700 individuals, which is a large amount,” said Wolter on the centre’s work.
“And then with regards to the captive breeding side of things we’ve managed to release just short of 100 individuals. So, you know, we like to believe that we’ve had significant impact on vulture species in at least South Africa.”
Matsvimbo and Wolter both said vultures have been given a raw deal by moviemakers in Hollywood, where they are almost always shown as evil and sinister.
