A biosurvey was conducted in Samendu Lake and its surrounding wetlands of Eastern Himalayan Hill region of Mirik in Darjeeling in West Bengal, India. In the study, endemic and locally rare bird species Zapornia bicolor (Walden, 1872)was studied with point transect method regarding its population and habitat. Very low population (only 21 individuals) and habitat degradation (encroachment, pollution, invasive plant species) was observed at the study sites. Conservation measures for this species have been suggested.
