"This success will lead to similar experiment elsewhere in the world and will help conserve and protect the birds," added Bibhab Talukdar, head of the Aaranyak conservation group that worked with the zoo to help breeding.
The storks, known as "hargilla" (bone swallower) in the Assamese language, were shunned before because of their smelly droppings, noisy calls and messy eating habits. But the Aaranyak project led a campaign to rehabilitate the species and its reputation in recent years. It assembled an award-winning brigade of village women conservationists to protect their nesting grounds, and set up the breeding platforms with Assam zoo in 2017.
"Finally we found success on November 26, 2019 when the first chick hatched," said Purnima Devi Barman, who leads the project. A second followed 10 days later.
Two three metre (10 feet) high bamboo platforms were erected in the zoo. The platform was about metre wide, the size of the stork's natural nest.
Nesting materials used by the birds in the wild were brought in for the Greater Adjutants to find. Their food supply was also carefully prepared. "The commotion created by zoo visitors was also monitored and care was taken so that the birds did not suffer from disturbance," said Mariswamy.
The Greater Adjutant is one of the rarest of the 20 species of stork left in the world. It is one of the eight species found in India. It is now only found in a few isolated districts in Assam and Bihar in India, and Prek Toal in Cambodia.
Bibhab said the loss of the tall trees where they usually nest, as well as poaching and poisoning have become major threats to the species. "Many historical breeding colonies have been lost," he said.
