Avifaunal diversity of Koradi Lake in Nagpur District of central India
Abstract
Birds, the feathered bipeds have immense ecological value and serve as the bio indicators of ecosystem health. Present study deals with the study on the avifaunal diversity of Koradi lake (Lat.- 21°15’0N; Longi.- 79°5’60E) which is situated 10 km. North to Nagpur city of Central India. Lake and the adjoining area was surveyed on fortnightly basis for a period of two years from 2008 to 2010. Out of total 76 species belonging to 15 orders in and around the lake 54 species were recorded as resident;09 species as seasonal local migrant and 13 species as winter migrant. Order Passeriformes (26 species) dominated the avifauna of the lake which was followed by order Ciconiiformes (10species). Birds like Purple moorhen, Purple heron, Indian pond heron, Parakeet, Green bee eater etc. were found to be native while Grey heron, Black-winged stilt, Painted Stork, Woolly-necked stork migrated locally. Birds like Red-crested Pochard, Gadwall, Northern Pintail, Wood Sandpiper, Northern Shoveler, Eurasian Wigeon, Chestnut-tailed Starling, Black Redstart and Blue-tailed Bee-eater as well as the raptors like Osprey, Eurasian Marsh Harrier and Common Kestrel were recorded as migrants. Presence of such diversified avifauna indicate the healthy status of the lake and needs proper management practices to avoid anthropogenic disturbances.
