Checklist of birds at Bhatye estuary and adjacent areas, Maharashtra Shital S. Taware1, Vishwajeet M. Lagade2, Deepak V. Muley3 and Kashinath B. Koli4 Abstract This study presents avian diversity of Bhatye estuary and adjacent areas where surveys have been conducted for two years (2009-2010) in five different localities, which were categorized on the basis of habitat differences. Total 113 bird species belonging to 14 orders and 41 families were observed at five different localities. Out of these 113 species, 80 species were residential, 17 species were residential (local) migratory and 16 species were migratory. Most of the residential and migratory species belonged to aquatic bird group. Some incidences were noticed regarding human interference, especially mangrove cutting for firewood, salting and drying of fishes under net and fencing commercial trees by nets to Fig.1 Site map of Bhatye Estuary and adjacent area avoid roosting by birds, which directly I- Mouth of the Bhatye estuary and Bhatye open coast, II- Mangrove Island, III- influenced avifauna.
