Site description This IBA site includes a large marshy tract with beels and grassland in eastern Assam. It lies partly in Dhakuakhana subdivision of Lakhimpur district (Sampora area) and Dhemaji district (Bordoloni area). Situated 50 km east of Lakhimpur town, this site is important for waterbirds. The terrain is flat, being on the floodplains. During monsoon, a major part of the IBA is completely inundated.
AVIFAUNA: Although a full checklist is not available, this wetland complex was covered during various waterfowl counts and information on many threatened species is available. Particularly noteworthy are records of the Endangered White-bellied Heron Ardea insignis and large populations of the Swamp Francolin Francolinus gularis (Choudhury 2000). Vultures (common till the 1990s), Greater Adjutant Leptoptilos dubius and Spot-billed Pelican Pelecanus philippensis are other important species recorded. This IBA was proposed as a bird sanctuary in late the 1980s (Choudhury 1991). It is highly likely to harbour the Blackbreasted Parrotbill Paradoxornis flavirostris, as there are past records from the adjoining areas (BirdLife International 2001). A few thousand waterfowl, including ducks and geese, winter in this area while a few thousand Amur Falcons Falco amurensis migrate through it during fall. The site also fulfils for A4i criteria (1% of biogeographic population) due to the congregation of Amur Falcon. There is a nesting record of the Near Threatened Lesser Grey-headed Fish Eagle Ichthyophaga nana (= humilis) (Choudhury 2000).
OTHER KEY FAUNA: The Hog deer Axis porcinus, Fishing cat Prionailurus viverrina and the Rhesus Macaque Macaca mulatta are noteworthy (A. U. Choudhury pers. comm. 2003).
