Biodiversity of Jal Mahal Lake and Kalakho Lake, Rajasthan, India with special reference to avifauna

摘要

This paper reports ecological studies with special reference to avifauna at Jal Mahal Lake (urban) and Kalakho Lake (rural), Rajasthan. Both lakes provide habitats for various migratory and resident birds. More than 180 species of birds, some listed in the Red Data Book, belonging to 49 families were recorded. The birds commonly sighted included some endangered, uncommon, vulnerable, threatened and near threatened species. The overall status of avifaunal species recorded was much better at the less polluted Kalakho Lake than at the Jal Mahal Lake. The human activity around the Jal Mahal Lake and agricultural practices in the dried up area seem to be responsible for the decline in the number of bird species. Drastic regulations are warranted to save these wetlands.
