India begins national Red List assessment of 1,211 bird species

India has started a nationwide Red List assessment of 1,211 regularly occurring bird species, establishing a rigorous scientific benchmark to safeguard native wildlife and direct conservation policy.

The exercise follows the global framework established by the International Union for Conservation of Nature (IUCN). Led by the Union Ministry of Environment, Forest and Climate Change, the assessment is being conducted jointly by the Zoological Survey of India (ZSI), the IUCN SSC Center for Species Survival India at the Wildlife Trust of India (CSS India–WTI), and the State of India’s Birds (SoIB) consortium.

Work is moving quickly. As of 19 October, scientists had completed preliminary assessments for 107 species, covering both resident and migratory birds. Officials expect preliminary assessments for all 1,211 species to wrap up by the end of this year, while the finalised national list is scheduled for completion towards the end of next year.

What the initial assessments show

The preliminary evaluations propose specific threat levels based on three core parameters: geographic range, population size, and population trends over time.

For high-priority birds such as the Great Indian Bustard, the proposed critically endangered status matches urgent habitat protections already underway in arid regions. Meanwhile, widespread species such as the Indian Roller are being marked as vulnerable to ensure population declines are tracked before they become irreversible.

A structured roadmap to 2030

The bird audit represents an early milestone in a much larger institutional programme. At the IUCN World Conservation Congress 2025 in Abu Dhabi, India presented its National Red List Roadmap and Vision 2025–2030. Under that plan, premier government bodies—including the Botanical Survey of India (BSI) and the ZSI—are collaborating with international and domestic partners to evaluate more than 11,000 species of flora, fauna, and fungi by the end of the decade.

Vivek Menon, Chair of the IUCN Species Survival Commission, said the national assessment represents a significant step forward in strengthening the scientific data that drives conservation work.

"The National Red List initiative of India represents an important step towards strengthening the scientific foundation that underpins conservation action," Menon said. "The collaborative assessment of Indian birds demonstrates how the wider expert community can work together to build a more comprehensive understanding of biodiversity and inform its long-term conservation."

Combining field science and citizen data

To fill existing gaps in wildlife counts, institutions have set up the National Red List Assessment of Birds Forum. The platform brings ornithologists and field biologists together to cross-examine evidence and refine species estimates.

The project draws heavily on citizen science collated by the State of India's Birds, which monitors population trends across widespread species. While absolute population estimates remain difficult to measure for every species, mass observational data gives researchers a clear trajectory of distribution shifts.

Aparajita Datta, Executive Director at the Nature Conservation Foundation and Co-Chair of the IUCN Hornbill Specialist Group, noted that pooling large volumes of citizen science data gives researchers an unprecedented opportunity to evaluate species that historically lacked structured monitoring.
