Journal Title: International Journal of Life Science - Year 2017, Vol 5, Issue 4
Abstract
Kolhapur is blessed with numbers of wetlands which is productive and unique ecosystem that support number of birds. The present study focus on avifaunal diversity and population status of threatened bird species by Diversity indices at in and around the wetlands of Kolhapur from 2016-2017. Bird survey was conducted according to line transect method and standard point count method. Species Diversity indices and Simpson index were used for statistical analysis. A total of 159 species of birds belonging to 17 orders and 60 families were recorded, of those 109 species of terrestrial birds and 50 species of water birds were observed. Out of 159 birds, 93 residential, 50 residential migratory and 15 are migratory. Of those one species is vulnerable, three species near threatened were observed. Among the birds recorded in study area, about 43% were insectivores and other dominating types include mixed diet 10%, piscivores 15%, omnivores 9%, carnivores 9%, granivores 9%, fructivores 2% and nectivores 3% respectively. Diversity of threatened birds was higher in Kalamba Lake as compare to other Wetlands. Urban wetlands are rich enough to attract birds and provide abundant food and safe passage for nesting, boosting and molting purpose.
