Population and Distribution of Avian Community at Different Habitat in and Around my School, Oussudu, Puducherry

Abstract

In the present investigation a total number of 45 species of bird were recorded in the entire study period which consists of 14 orders and 30 families. Some of the species yet to be identified. Out of 45 bird species, 44 (97.77%) bird species were Resident (R) and one (2.23%) species was Migrant (M). The minimum population density of bird species recorded were Green Bee–eater (17.25Birds/m2), Grey Heron (3.50 Birds/m2), spotted Dove (6.13 Birds/m2), On the other hand, maximum population of bird species recorded were Red Vented Bulbul (359.25 Birds/m2), House Crow (320.25 Birds/m2), Baya Weaver (695.63 Birds/m2). Overall analysis of the birds sighted in two month periods more number of birds seen in wet marshy land followed by agricultural land and school. The study proved that the disturbance over the school area and less distribution of green patches, shrubs, bushes and trees make less preference of bird. The study also strongly says if the present ecological characteristics of wetland continue, the birds were unable to inhabit this habitat in the immediate future. Proper awareness regarding the importance of birds to the local people, through different programmes will ultimately help the protection of birds of this region. In the present study variations in the diversity of birds, based on Shannon-wiener diversity index, in different habitats was carried out. Overall Maximum diversity index was recorded during monsoon season (x = 3.241) and minimum diversity index was recorded during pre - monsoon seasons (x = 3.139).
