Abstract

Understanding the diversity and structure of bird communities is essential to delineate the importance of regional or local landscapes for avian faunal conservation. Birds are an essential â�?�?bio-indicatorâ�? and are very sensitive to environmental changes. The use of bio-indicator as a tool in conservation of landscape ecology is becoming widespread. Based on this aspect, we have taken an effort to study the avifaunal diversity of south Chennai lakes and also to conserve the lakes from anthropogenic activities. A random survey was conducted in five lakes of south Chennai from 2013 onwards. We recorded 43 different bird species belonging to 29 families and 12 orders. The results revealed that, in the habitat status, 11 species come under resident migrant and 32 species come under resident. Moreover, from the noticed species 1 sp. is very common, 22 sp. are common, 9 sp. are rare and occasionally 11 sp. were noticed. According to the International Union for the Conservation of Nature (IUCN) Red list 2015 status, we have recorded near threatened 3 sp., (Pelecanus philippensis, Mycteria leucocephala, Threskiornis melanocephalus and least concern 40 species. Among these 43 species, 17 sp. are terrestrial and 26 sp. are aquatic. These bio-indicators are a good medium for pollination, seed dispersal and biological control and even they play a vital role to continue the ecological cycle. Increasing urbanization, industrialization and other anthropogenic activities are posing a great threat to this avifaunal diversity.
