An attempt has been made for the very first time for ecological investigation of birds at Bakhira bird sanctuary, district Sant Kabir Nagar, Uttar Pradesh, India .Thirty-two species of birds were observed during the field investigation. The line transect method was employed for population estimates. During the field survey, we recorded a significantly higher number of migratory birds at the end of early winter (December) and at the commencement of middle winter (January). Red crested pochard (Netta rufina), Common coot (Fulica atra) and Gadwall (Mareca strepera) were the most populated species in the present study. The number of birds was not significantly different among winter months except between October/December and October/January wherein, we found significant variation in the number of birds at the Bakhira tal. Of the five main habitat types viz. lowland vegetation, upland vegetation, emergent vegetation, open water and agricultural fields, the most utilized were lowland vegetation and the emergent vegetation in the early and middle wintering stage. While in late winter, the emergent vegetation was the most utilized habitat. The findings of the present study provide the baseline information about the population of migratory birds and the rate of habitat utilization at the Bakhira bird sanctuary.Grey heron, Common Red shank, Spotted Red shank, Long toed Stint, Little Stint, European White Stork and common Sand Piper were recognized as Wintering waders in Bakhira Tal, were highly susceptible to continuous anthropogenic pressures in the form of washing of cloths, cattle bathing, cattle grazing, and entry of domestic sewage, hunting, fishing, and expansion of crop lands. Since crop lands are being destroyed by waders to some extent, Man &Wild conflict was also observed among the local people of study area and waders. Consequently, villagers started scaring campaigns by exploding crackers near the waders to make them fly from the wetland.
