The State of India’s Birds 2020 (SoIB), a new scientific report was jointly released by 10 organisations. It was produced using a base of 867 species, and analysed with the help of data uploaded by birdwatchers to the online platform, eBird
- Over a fifth of India’s bird diversity, ranging from the Short-toed Snake Eagle to the Sirkeer Malkoha, has suffered strong long-term declines over a 25-year period.
- More recent annual trends point to a drastic 80% loss among several common birds.
- For every bird species that was found to be increasing in numbers over the long term, 11 have suffered losses, some catastrophically.
- Of 101 species categorised as being of High Conservation Concern endemics such as the Rufous-fronted Prinia, Nilgiri Thrush, Nilgiri Pipit and Indian vulture were confirmed as suffering current decline.
- Among widely known species, the common sparrow, long seen as declining in urban spaces, has a stable population overall, although they have become rare in cities and urban areas.
- Raptors overall are in decline, with ‘open country’ species such as the Pallid and Montagu Harriers, White-bellied Sea Eagle and Red-necked Falcon suffering the most.
- Migratory shorebirds, along with gulls and terns, seem to have declined the most among waterbirds.
