Vulture populations in one of Africa's most significant wildlife reserves have declined by 60%, say scientists. insurance
The researchers suggest that the decline of vultures in Kenya's Masai Mara is being driven by poisoning.
The US-based Peregrine Fund says farmers sometimes lace the bodies of dead cattle or goats which has a poisonous pesticide known as furadan.
This seems to be aimed at carnivores that kill the livestock, but a single carcass can poison up to one hundred fifty vultures.
Munir Virani, who is director with the Peregrine Fund's Africa programmes, has known as for use of furadan to be banned in the region "to preserve these keystone members with the scavenging community".
"People may possibly think of vultures as unsightly and disgusting, however the birds are necessary for your ecosystem," he says.
Their style for carrion basically makes them the landscape's clean-up crew - making certain the region is just not littered with bodies, assisting consist of the spread of disease and recycling nutrients.
The outcomes of this most recent survey of vultures are printed in the journal Biological Conservation.
The terrible implications of a vulture population crash have currently been demonstrated all through a case that became generally known as the Asian vulture crisis.
Populations of Gyps vultures in particular, in South Asia, crashed by greater than 95% around only a few years in the 1990s, mostly since farmers treated their cattle with all the pain-killing drug diclofenac.
The pain-killer, it turned out, was lethal towards the vultures, which fed around the dead cattle.
At the same time as driving 3 species of vulture towards the brink of extinction, the crisis furnished an enormous level of food for wild dogs, which moved in to take the location with the birds.
This had the devastating side-effect of rising the spread of rabies. And Dr Virani is involved that a similar situation could take place in Kenya.
The resolution in Africa although, could be far more easy than in South Asia.
By boosting the public picture of vultures in the region, the Peregrine Fund hopes to end people from carrying out these "revenge poisoning attacks".
Amongst 2003 and 2005, Dr Virani and his colleagues drove throughout the expansive Kenyan landscapes, counting vultures.
He and his colleagues then compared the results of these surveys with all the success of surveys completed in the 1980s. The comparison revealed a 60% decline in vultures.
Corinne Kendall's do the job has taken this survey a action more.
Ms Kendal is a researcher from Princeton College in the US, that has also been doing work with all the Peregrine Fund - monitoring and monitoring the birds to research the extent with the poisoning.
"We connected the GPS trackers like little backpacks," she tells BBC Information. "There's a piece that sits on their chest and two loops all around every wing."
"But we had four out of 16 vultures killed in the very first calendar year and 3 of those had been confirmed situations of poisoning.
"From a sample of 16, it really is challenging to understand how consultant that is certainly, but it really is particularly worrying."
