Assam releases captive-bred vultures into wild in global first
Vultures are big birds that help keep the environment clean by eating dead animals.
Many years ago, a medicine given to farm animals made vultures very sick, and nearly all of them disappeared from India.
Scientists and forest workers started a special programme to raise vulture chicks safely in captivity.
In Assam, a state in India, the birds were cared for until they were strong enough to live in the wild.
On Friday, ten vultures stepped out of a special enclosure into the forest.
It was the first time anywhere in the world that captive-bred vultures were released into the wild like this.
A rope and pulley opened the gate from far away so the birds would not be frightened by people.
Each vulture wears a blue ring on its leg and a tag on its back so officials can watch where they go.
People are being asked not to use harmful medicines on animals so vultures can safely return.
Ten captive-bred vultures — five slender-billed and five white-rumped — were soft-released into the wild at the Jatayu Soft Release Centre in Tewaripal, Biswanath district, Assam, in what officials described as a global conservation first.
The release is the culmination of a conservation breeding programme jointly run by the Assam forest department and the Bombay Natural History Society (BNHS) since 2007.
India's Gyps vulture populations declined by 99 per cent in the last 20 years due to poisoning from veterinary non-steroidal anti-inflammatory drugs, particularly diclofenac, which the government has since banned.
The birds were shifted from the Vulture Conservation Breeding Centre at Rani to the release aviary three months ago for acclimatisation before their introduction to the wild.
The aviary gate was opened from a distance using a pulley, officials monitored movements from a CCTV-equipped tower, and each bird carries a numbered blue leg ring and back tag for tracking.
