    Vulture Population in India

    • Declining status: 
      • Number of vultures has seen a constant decline since the 1990s.
      • Between the 1990s and 2007, numbers of three presently critically-endangered species, the Oriental white-backed, long-billed and slender-billed vultures, decreased massively with 99% of the species having been wiped out.
      • The number of red-headed vultures, also critically-endangered now, declined by 91% while the Egyptian vultures by 80%.
      • The decline in vulture populations came into limelight in the mid-90s.
    • Importance of Vultures:
      • Vultures are  carcass feeders & play a significant role in the natural mechanism of infection control.
        • Despite feeding on infected carcasses, vultures do not get infected. The acids in their stomach are potent enough to kill the pathogen.
      • It will clean up, and keep the ecosystem healthy.
      • The birds also prevent the contamination of water sources, especially in the wild. 
    • Causes for decline:
      • Use of Diclofenac: A veterinary nonsteroidal anti-inflammatory drug (NSAID) in 2004 found in the carcass of cattle the vultures feed on. 
        • The veterinary use of this was banned in 2008.

    • Pesticides: The presence of organochlorine pesticide, polychlorinated biphenyls, polycyclic aromatic hydrocarbons and heavy metals were also the cause of mortality.
    • Lack of Nesting Trees
    • Electrocution by power lines
    • Food Dearth and Contaminated Food

     

    • Conservation Efforts
      • Vulture Action Plan 2025
        • The Vulture Safe Zone programme is being implemented at eight different places in the country where there were extant populations of vultures, including two in Uttar Pradesh.
      • The Central Zoo Authority (CZA) and Bombay Natural History Society (BNHS) also established the Vulture Conservation Breeding Programme.
      • The MoEFCC released the Action Plan for Vulture Conservation 2006 with the Drugs Controller General of India (DCGI) banning the veterinary use of diclofenac in the same year.
      • At present, there are nine Vulture Conservation and Breeding Centres (VCBC) in India, of which three are directly administered by the Bombay Natural History Society (BNHS).

    Way Ahead

    • There is a need for the strict implementation of the Insecticide Act 1968 to regulate the use of pesticides.
    • Creating awareness among the cattle owners is the only way to prevent deliberate poisoning aimed towards eliminating problematic large carnivores.
