Sambalpur, Odisha — A migratory bird census has begun at Hirakud Reservoir, a Ramsar site and one of Asia’s largest artificial lakes, marking the start of annual efforts to monitor avian biodiversity in the region.

Background Hirakud Reservoir serves as a winter haven for migratory birds from Central Asia, Siberia, and the Arctic. The census, conducted annually, aims to assess population trends and conservation needs. This year’s exercise follows protocols established by the Indian government’s Wetlands (Conservation and Management) Rules, 2017, and builds on data from past surveys that recorded over 100 species, including the critically endangered Siberian Crane.

Context and History The reservoir’s ecosystem supports a diverse array of wetland-dependent species, with numbers peaking between November and February. Previous censuses, initiated in the early 2000s, have highlighted fluctuations in bird populations due to climate shifts and human activity. Conservationists emphasize that the data informs regional policies to balance ecological preservation with developmental projects in the Sambalpur region.

Full Verified Sequence of Events Teams of ornithologists, supported by state forest department personnel and volunteers, began the census on 19 January 2026. Using systematic line-transect methodology, they will survey designated zones of the reservoir over the next three weeks. Key species under observation include the Bar-headed Goose, Common Pochard, and Ruddy Shelduck. Officials report that preliminary counts suggest a stable trend in numbers, though final data will be compiled post-census.

Community Impact Local communities, particularly fisherfolk and farmers, have expressed mixed reactions. While some welcome the initiative as a step toward preserving ecological balance, others cite concerns over restricted access to certain reservoir areas during surveys. District forest officer R.K. Meher assured that coordination with village leaders would mitigate disruptions. “We’re working to ensure the census doesn’t interfere with livelihoods,” he said, adding that awareness campaigns are underway to educate residents on coexisting with migratory birds.

Local Significance The census holds particular importance for Sambalpur, where the reservoir is a lifeline for agriculture and biodiversity. Conservationists note that the data will aid in drafting a management plan to protect the wetland from encroachment and pollution. The district administration has pledged support for initiatives to promote eco-tourism, aligning with Odisha’s broader goals to conserve its natural heritage.

What Happens Next The final census report, expected by late February, will be shared with the National Biodiversity Authority and the state’s environment department. Based on findings, authorities may propose measures such as habitat restoration and stricter anti-poaching patrols. For now, the ongoing survey underscores Sambalpur’s role as a guardian of migratory bird corridors in eastern India.
