For the first time, a report on the grassland bird survey has been published in Kaziranga National Park. This survey identified 43 different species of grassland birds, including one critically endangered and two endangered species. Based on these findings, Kaziranga has been recognized as one of the significant regions for grassland bird diversity in India.
Conducted between March 18 and May 25, 2025, the survey covered parts of eastern Assam, including Biswanath and Nagaon districts. Researchers collected data using point counts and sound recording equipment to observe bird activity in specific locations.
The survey focused on ten bird species that are either globally threatened or found exclusively in the floodplain of the Brahmaputra River. Notable among these species are the Bengal Florican, Swamp Francolin, and the Finn’s Weaver. The discovery of a breeding colony of the endangered Finn’s Weaver in the Kohora range is particularly significant, indicating healthy conditions in the grasslands. These birds are known for their unique nests built on trees.
The use of sound recording devices has greatly assisted researchers in tracking birds without disturbing them, resulting in improved accuracy in data collection, especially for shy species.
The report sheds light on the vital grasslands in Kaziranga, which support vulnerable bird populations. It emphasizes the need for effective conservation and management of these habitats.
The survey was executed with the collaboration of forest officials, scientists, and conservationists, who provided significant contributions to the effort.
This survey represents a crucial step in the conservation of grassland birds. It highlights the importance of ongoing monitoring and management for safeguarding fragile ecosystems. Kaziranga is known as a global biodiversity hotspot and serves as an essential sanctuary for birds. The insights gained from this survey could serve as a model for similar research and conservation initiatives in India and beyond.
