As the world marks the International Vulture Awareness Day, the Nigerian Conservation Foundation, NCF, on Saturday underscored the importance of vultures in the maintenance of balance in the ecosystem.
The NCF in a communique released after its five days webinar forum on Vultures, made available to news men in Lagos, noted that vultures were sanitary officers with a clean-up service on the environment.
The Director of Technical Programmes at the Foundation, Dr Joseph Onoja, in his presentation revealed that nature had bestowed on humanity vultures with the role of environmental sanitary officers with a clean-up service worth $11,000 a year.
Without vultures, humans are vulnerable to the spread of infectious diseases, because in the absence of vultures, dogs and rats become the clean-up crew.
“’The danger in this is that these animals are not equipped for such and are close to human population, exposing us to diseases.”
In his presentation, Mr Aniekan-Abasi Emmah Uwatt, a conservation biologist and ornithologist, observed that human activities were the major drivers to the vultures’ threatened status.
He added that the world could suffer from negligence if something drastic was not done to preserve the remaining vulture species in Nigeria.
“Imagine a world without vultures, it will lead to disease outbreaks such as anthrax; rabies and botulism.
‘“We would also have dirty environment with dead carcasses and foul smells,” he said.
Another facilitator, Mr Apeverga Paul Tersoo, Lecturer, Federal University, Dutse, Jigawa State , said that vultures might not be very appealing by their looks, but these birds, also known as scavengers do the dirty jobs of cleaning our environment.
Tersoo said they do this by taking care of carcasses and preventing the spread of diseases, which in turn keeps the ecosystem healthy.
“’The importance of these natural environmental cleaners cannot be over emphasised because the benefits we derive from them for free will cost us so much that it can only be imagined.
“A case study is seen in India where a crash in the vulture population was observed after the birds fed on carcasses of livestock that were treated with Diclofenac.
“The Indian white-rumped vulture was the most hit, with a decline rate of 99.9 per cent.
“What followed was a surge in population of feral dogs that were infected with rabies from litters of carcasses as a result of the absence of our natural cleaners (the vultures).
“Consequently, an increase in human deaths from rabies nearly caused a public health catastrophe that saw the government of India spending about $34 billion to fight the spread of the disease,” he said.
Malam Samaila Mohammed Alkali, Airport Wildlife Hazard Management Coordinator, Kano Airport, said that aviation was a major threat to the survival of vultures.
“This is due to bird strike. Bird strikes occur when bird physically collide with aircraft,” Alkali said
According to him, approximately 10,692 vultures were killed by aircraft between 2008 and 2015, these may represent 1,500 Vultures killed every year for the period of seven years.
Meanwhile, in his presentation, Mr Adewale Awoyemi, Head of Forest Centre, Institute of Tropical Agriculture (IITA), Ibadan observed that the vanishing vultures had critical implications on human health and existence.
Awoyemi said that the destruction of their habitats by deforestation was a threat to vulture conservation.
International Vulture Awareness Day (IVAD) is celebrated on the first Saturday of September every year to reflect on the importance of vultures and the essential role they play in a healthy ecosystem.
It also aims at spreading awareness about range of threat facing vultures and urge the people to take action and prevent extinction of the ecological bird specie.
