The short answer
Bordoibam-Bilmukh Bird Sanctuary: what visitors should know first
Only for committed bird watchers with a spare day. Bird numbers have fallen sharply, visitor facilities are not published and the trip is long, so go in winter with a local guide and confirm access with the forest office first.
History and context
The story behind Bordoibam-Bilmukh Bird Sanctuary
The wetland is described as a freshwater lake formed after the 1950 Assam earthquake, once connected to the Subansiri River, which now runs several kilometres away. It was declared a wildlife sanctuary in 1996 and covers roughly 11.25 square kilometres on the boundary of Dhemaji and Lakhimpur districts.
A 2022 to 2024 survey recorded 47 bird species, against 167 species noted in 1997. The researchers link the fall to habitat destruction, disturbance and bird hunting.

Why it matters
Why Bordoibam-Bilmukh Bird Sanctuary is worth your time
Bordoibam-Bilmukh is a remnant of the wetlands that once spread across the Subansiri floodplain. It formed as a lake after the 1950 earthquake and was declared a wildlife sanctuary in 1996, which makes it one of the few protected bird wetlands in this part of upper Assam.
It also shows what is at stake for the region's birds. Studies there recorded 167 species in 1997 but only 47 in a 2022 to 2024 survey, with Lesser Adjutant and Greater Adjutant, both Near Threatened, among those still present. For visitors who watch birds at Majuli's beels, seeing a stressed wetland helps explain why the island's adjutant colonies matter.
Highlights
What not to miss
- 01
Winter waterfowl
Migratory ducks and wading birds arrive in the cold months, making November to February the time to go.
- 02
Adjutant storks
Lesser Adjutant and Greater Adjutant, both Near Threatened, are among the larger birds still recorded here.
- 03
A wetland under pressure
The sharp fall in species since 1997 makes it a sobering, honest look at wetland conservation in Assam.
Plan your visit
How to experience it
Plan this as a full-day expedition rather than an add-on. It lies on the north bank of the Brahmaputra, away from Majuli's ferry routes, so ask your host or a Jorhat tour operator to work out the road route, check the sanctuary is open and recommend a driver who knows the area. Do not rely on a fixed timetable or a map pin alone, as access tracks change with the floods.
Go in winter, between November and February, and reach the water at first light. Winter brings migratory waterfowl, and the wetland also supports resident birds such as the adjutant storks, egrets, herons and bitterns. Walk slowly along bunds with binoculars, keep quiet and stay out of the marsh.
Set your expectations honestly. A recent survey recorded far fewer species than in 1997, and hunting and habitat loss are blamed, so this is a place to see a modest wetland with patience, not a large bird spectacle. Carry food, water and a warm layer for the day.
