Subsidence and upliftment of landmass were encountered in Andaman & Nicobar Islands due to the 2004 tsunami. The subsided landmass at the coastal front was permanently waterlogged ensuring a conducive new habitat for wetland birds. Pre- and post-tsunami Landsat satellite data products were used to demarcate the permanently waterlogged areas. A total of 63 bird species belonging to nine families comprising of five orders were identified and documented through direct observation technique in six stations of the 2004 post-tsunami-created wetlands in South Andaman. Order Charadriiformes and Anseriformes recorded the highest (47.62%) and least (4.76%) taxonomic composition of wetland birds, respectively. Scolopacidae family recorded the highest (56.67%) species composition. Among the six stations, the highest diversity of birds was observed in Sippighat and Ograbraj stations.
