Avifaunal assemblage in Urban ponds of Thirupparankundram and Koothiyarkundu, Madurai District, Tamilnadu, India

摘要

The present study deals with the species abundance, diversity and species richness of avian communities in Thirupparankundram and koothiyarkundu ponds, Madurai, Tamilnadu, India. Forty nine species of birds belonging to 29 families under 42 genera were recorded. Shannon_H and Fisher's alpha diversities, species evenness, species richness of bird communities and number of bird species in Thirupparankundram and koothiyarkundu ponds are discussed. Analysis of variance (ANOVA) for observed data was carried out and number of individuals, Shannon_H and Menhinick indices are significant. The study area was visited and surveyed in October, November and December 2018. During each visit waterfowl census was carried out and water samples were also collected todocument changes in physico-chemical parameters. Pearson's correlation coefficient (r) value is determined using correlation matrix to identify the highly correlated and interrelated water quality parameters. In both ponds, Chloride and Acidity are positively correlated and significant at the level of 0.05.
