Loss of vultures damaging for humans, ecosystem: study

There are quite many of the species of the world which are slowly moving towards the verge of extinction. The primary among the birds includes vultures. The primary threat to the vultures includes the toxins being present in the carrion which they consume. This particular loss being caused to the vultures is allowing the other scavengers for flourishing and the proliferation of such scavengers is allowing for bringing the viruses and bacteria for carcassing over into the human cities. According to the report being released by the biologists of University of Utah, such a kind of loss would be proving to be serious consequences in terms of the ecosystems and even to the Indian populations.The findings is being published in the Journal Biological Conservation.

Vulture: Under Extinction

On many of the continents this vultures are being the unfortunate victims of the poisoned carcasses which is especially impactful. Populations of many of the vultures from around the world is either now being declining or over the brink of the extinction. During 2004, Şekercioğlu published a study being examining the repetitive extinction risk of all of the bird species. He specially noted that vulture is the single most threatened group of the birds. Even now decades later, Buechley and Şekercioğlu has examined the factors which are affecting the extinction risks of quite more than 100 of the bird species which is also including 22 species of the vultures which is eating carrion exclusively.

The results are quite suggestive of the several inherent ecological traits which can possibly contribute towards the risk of extinction of the vultures, which is also including their large body mass, slower productive rates, and also the highly specialized diets. The main cause of the extinction was mainly being detected to be a drug being named as diclofinac which is a veterinary anti-inflammatory drug which has relieved the pain in the cattle. But it is proving to be very toxic in case of the vultures.

Flocking over the cattle carcass

Hundreds of the vultures would be flocking for each of the cattle carcass. If the cattle is being recently treated with the diclofinac, hundreds of the vultures would possibly die. Looking into the view of the highly gregarious behaviour which is being less than one percent of the cattle carcasses being contaminated with the diclofenac is being accounting for the steep decline of the vulture. Looking at the decline of the vultures, India is being experiencing a strong uptick of the feral dogs which is quite estimated to be one million.

The rise of the dogs which is ultimately being feeding over the disease-ridden carcasses is being thought to be having atleast partially caused rabies outbreak which is being estimated to have killed about 48,000 people from the duration of 1992-2006 in India. Deaths may possibly been avoided if not for the case of disappearance of vultures. Now the centre of the vulture crisis is now in the sub-saharan Africa. In case of Africa it is quite lot more challenging being the darkest story.
