In 2007, the number of greater adjutant storks in India’s Assam state was estimated to be as low 450. The hargila, as it’s known locally, was classified as endangered.

Seeing the peril the bird was in, biologist Dr Purnima Devi Barman knew she had to intervene.

With the help of 10,000 rural women, Barman became the driving force in safeguarding the nests of storks as well as rebranding the prehistoric-looking scavenger from a bad omen to positive cultural symbol. The women became known as ‘Hargila Army’ or ‘Stork Sisters’.

Such was the success of the campaign that the International Union for Conservation of Nature (IUCN) reclassified the stork from Endangered to Near Threatened in December 2023. Since 2007, numbers have quadrupled in Assam to more than 1,800.

Recognising the incredible work, the Whitley Fund for Nature (WFN) have presented Barman with the 2024 Whitley Gold Award – an honour that recognises and celebrates grassroots conservation leaders – for her contribution to the project.

Aided by funding received with the Whitley Gold Award, Barman is now planning to double the Hargila Army to 20,000 women and expand from Assam to the Indian state of Bihar and overseas to Cambodia, covering all three remaining breeding grounds of the bird.

The Hargila Army is growing, with plans for the group to increase from 10,000 to 20,000 women. The community hopes to increase the population of storks to 5,000 birds by 2030 by expanding work overseas to Cambodia via local community programmes as well as to the state of Bihar in East India.

Barman’s outreach extends to schools. In one campaign, known as ‘village-to-village’, Barman and her team run impromptu field visits with locals that can last all day. “Magic happens when we involve communities.
