The Royal Society for Protection of Nature (RSPN Bhutan), a Conservation Allies partner, recently completed their 2025 annual survey of the Critically Endangered White-bellied Heron (Ardea insignis). Known for being one of the rarest birds in the world, this species faces immense threats across its limited range in Bhutan, India, and Myanmar. One of RSPN Bhutan’s main projects is to reverse the decline of this species. This year’s survey—conducted from March 3 to 7—counted a total of 29 individuals in Bhutan, including 24 in the wild and 5 at the White-bellied Heron Conservation Center (WBHCC). This represents a 15% increase from 2024.
The survey covered 17 of Bhutan’s 18 identified habitat zones using targeted field efforts and digital tools. The majority of wild sightings occurred in the Punatsangchhu River basin, where 12 individuals were observed. Four active nests were also documented—three in the Punatsangchhu basin and one in the Mangdechhu basin—signaling hopeful, though fragile, breeding success.
In addition to the heron data, surveyors recorded 178 bird species and 16 mammal species across the landscape, highlighting the region’s rich biodiversity. However, the survey also documented escalating threats to riverine ecosystems, primarily from habitat loss, infrastructure development, and pollution. RSPN Bhutan’s efforts to mitigate these impacts include habitat restoration, community outreach, and the establishment of the WBHCC, where promising breeding pairs are being nurtured for future reintroductions.
Conservation Allies is proud to support RSPN Bhutan in this vital work to protect the White-bellied Heron. Each year’s count not only reflects the species’ tenuous foothold in the wild, but also underscores the importance of sustained conservation action in one of its last strongholds.
