Bhutan serves as a haven for avid bird watchers and ornithologists, boasting records of over 670 bird species, with many more awaiting discovery. About 50 of the identified species are migratory birds that seek refuge during the winter months. Birds falling under this category include ducks, waders, raptors, thrushes, finches, and buntings.

Bhutan also provides sanctuary to several endangered bird species. Specifically, it is home to the Imperial Heron, considered one of the world’s fifty rarest birds, and the elusive Black-Necked Crane. Following breeding in Tibet, this crane species journeys over the Himalayas to winter in Bhutan. Its preferred locations include Phobjikha Valley in Western Bhutan, Bumthang in Central Bhutan, and Bomdeling in Eastern Bhutan. This migratory journey typically begins in the months of September or October, with a return flight to Tibet occurring between February and March.
