Abstract

Birds have been considered as useful biological indicatorsbecause they are ecologically versatile and inhabit all kinds of habitats. Wetland sare fringe habitats between terrestrialand aquaticeco systems. Wetlands are the most preferred habitats for water birds. They support the birds by way of feeding, roosting, nesting and rearing young ones. Birds are essential animal group of an ecosystem and maintain a tropic level. Bird migration is a phenomenon it includes the regular, seasonal movement of populations from one geographic location to another, and is common among most varieties of birds that has long fascinated scientists and other observers. It is marked by the eventual return to the original place of departure and is most evident among certain bird species that usually follow a yearly cycle. Migratory waterfowls are one of the most remarkable components of global biodiversity. Water birds are not only the most prominent groups which attract people to wetlands, but also are good bio-indicators and useful models for studying a variety of environmental problems. The present investigation was carried out to document the variation of Diversity, Seasonal variation, Abundance and Migratory behavior of Local and Migratory Water birds, Wetland-associated bird species of Mukutmanipur dam, Bankura, West Bengal India, from December 1017- March 2018. The present study recorded 81 bird‘s species of 13 families. In which 61% species are migratory of which 59% & 3% species are winter migratory & summer migratory respectively. The maximum tradition of birds are come to the MukutmanipurDam in winter season in the month of December to February. It indicate the high rate of productivity of the wetland. Beside this but 12 Vulnerable, 4 Near Threatened, and also 8 Endangered Species also recorded. This represents the reflection ecological importance of the dam.
