Raptor Migration in Nepal: Watching Eagles Cross the Himalayas
Each autumn, hundreds of thousands of raptors navigate the Himalayan ridgelines of Nepal in one of the world's most spectacular avian migrations.
Overview
Nepal hosts one of Asia's most dramatic raptor migration spectacles each autumn. From late September through November, raptors travelling from their breeding grounds in Central Asia and Siberia navigate southward along the Himalayan axis, funnelling through passes and ridgelines before descending to their Indian and Southeast Asian wintering grounds. The Himalayan barrier concentrates these birds along predictable routes, creating exceptional count sites where hundreds of thousands of birds of prey can be observed in a single season.
The Annapurna massif and the hills above Pokhara are the most productive raptor watch sites. The Indreni viewpoint near Sarangkot, and the ridge trails above Naudanda, record enormous daily counts during peak migration. Common species include Steppe Eagle, Booted Eagle, Amur Falcon, Eurasian Sparrowhawk, Crested Honey Buzzard, and Osprey. On peak days in October, single-site tallies of over 10,000 Steppe Eagles have been recorded.
The Amur Falcon migration is particularly striking. These small falcons travel from breeding grounds in northeastern China and Russia to wintering grounds in sub-Saharan Africa — one of the longest falcon migrations on earth. Flocks of thousands sweep through Nepal's midhill country from late October into November, resting in farmland and secondary forest at night before resuming their journey.
Raptor watchpoints are accessible by short hikes from Pokhara (Sarangkot, Kaskikot) and from Kathmandu (Champadevi, Phulchowki). No permits are required, and counts are best from sunrise to 10am when thermals begin forming.

FAQ
Q: When is peak raptor migration season in Nepal?
October is the peak month. The second and third weeks of October consistently produce the highest daily counts of Steppe Eagles and other soaring raptors. Amur Falcons peak in late October through the first week of November.
Q: Do I need specialised equipment for raptor watching?
Binoculars (8x42 minimum) are essential. A spotting scope helps with distant identifications and is worth carrying to popular watchpoints. A field guide to South Asian raptors or a raptor identification app will help distinguish similar species in flight.
