The area around Kilbury and Pangot has historically been a part of the Kumaon region, known for its rich biodiversity and strategic importance. While the specific establishment date of the sanctuary is not widely documented, its importance as a birding hotspot has been recognized for decades. The British colonial era saw increased interest in the region's natural resources, leading to some initial conservation efforts. Post-independence, the focus shifted towards formally protecting the area's unique ecosystem and promoting responsible tourism. Over the years, local communities have played a crucial role in preserving the sanctuary's natural heritage, contributing to its continued success as a haven for wildlife and birds. Today, it stands as a testament to the importance of conservation and sustainable tourism practices.
