In a historic conservation milestone, the world's first captive-bred slender-billed vultures have been released into the wild in Assam's Kaziranga National Park.

Key Takeaways

  • World's first-ever release of captive-bred slender-billed vultures (Gyps tenuirostris).
  • 10 vultures (5 slender-billed and 5 white-rumped) released at Kaziranga National Park.
  • The decline of Gyps vultures in India stands at a staggering 99% over two decades.

In a landmark moment for global wildlife conservation, Assam has witnessed the world's first-ever release of captive-bred slender-billed vultures. The birds, bred at the Bombay Natural History Society (BNHS) conservation facility near Guwahati, were released into the wild at the Kaziranga National Park and Tiger Reserve on August 7, 2026.

The release included five slender-billed vultures and five white-rumped vultures. These scavengers had undergone a three-month acclimatization period at a specialized aviary in the Biswanath Division before being introduced to their natural habitat at the Jatayu Soft Release Centre. The event was attended by Assam’s Environment and Forest Minister Jayanta Mallabaruah and senior forest officials.

Why This Matters

BozokMedia analysis shows that this release is a critical intervention to prevent the total extinction of these scavengers. Vultures play a vital role in the ecosystem by consuming carcasses, thereby preventing the spread of diseases. However, the population of Gyps vultures in India has plummeted by 99% over the last 20 years, primarily due to the ingestion of toxic veterinary painkillers like diclofenac.

"This is the first such release of the captive-bred slender-billed vulture in the world," stated Sachin Ranade, Deputy Director of BNHS.

Despite government bans on several veterinary drugs—including aceclofenac, ketoprofen, and nimesulide—secondary poisoning remains a lethal threat. Since 2018, more than 700 vultures have died in Assam due to accidental poisoning from pesticides often used illegally to target stray dogs.

Historical Background

The vulture crisis in India began in the late 1990s when the widespread use of diclofenac in livestock led to massive die-offs. This triggered a massive conservation movement led by organizations like the BNHS, which has been working alongside the State Forest Department since 2007 to breed and protect these essential species.
