Bhubaneswar: In a remarkable outcome of the mid-winter waterfowl census, Odisha’s wetlands have recorded over 15 lakh birds belonging to more than 200 species. The census, conducted by the Odisha State Wildlife Organisation, highlights the state’s thriving avian biodiversity and its importance as a haven for migratory and resident birds.
The Chilika Lagoon and Mangalajodi Wetlands stood out as key hotspots, recording a total of 11,27,228 birds from 196 species, an increase of nine species compared to the previous year. Migratory birds dominated the count with 10,87,226 individuals spanning 109 species, while resident birds accounted for 40,002 across 87 species. The Nalabana Sanctuary within Chilika Lagoon alone hosted 92 species, with a bird population of 3,43,226, reaffirming its status as a vital habitat for waterfowl.
The census in Chilika was conducted by dividing the lagoon into 21 segments, with 19 surveyed by boat and two covered by road, ensuring thorough documentation of bird populations.
Hirakud Reservoir, a vast 700 sq km expanse, recorded 3,77,732 birds from 122 species. The survey involved 32 teams and 70 participants, systematically covering 21 designated sectors.
Bhitarkanika National Park also showcased its ecological significance with 1,51,614 birds from 118 species. Among the most populous species observed were the Lesser Whistling Duck (44,825) and the Northern Pintail (18,776). The Paradeep Gypsum Pond area, part of Bhitarkanika’s ecosystem, emerged as a critical hotspot for bird congregations.
One of the key highlights of the census was the sighting of the Great Bittern at Gahirmatha, a rare observation that excited ornithologists and conservationists alike.
For the first time, the waterfowl census extended across the entire state, covering major wetlands such as Chilika, Bhitarkanika, and Hirakud. Over 200 participants, including forest staff, ornithologists, researchers, and volunteers, were equipped with spotting scopes, binoculars, and data sheets to ensure accuracy in bird identification and counting.
The comprehensive approach to the census, dividing wetlands into strategic sectors for detailed coverage, has provided invaluable data on Odisha’s avian diversity. The findings underline the importance of Odisha’s wetlands as a sanctuary for birds and a critical component of global biodiversity conservation efforts.
