Main Article Content
The composition and status of waterbirds in Perur-Sundakamuthur Lake, a wetland in Coimbatore, Tamil Nadu, was studied from May 2014 to April 2016. This wetland is home to resident and local migrant birds throughout the year and is also used by winter migrant birds during a part of the year (September to March). From the data collected so far, the highest number of birds and species diversity was recorded from February to April. It is, therefore, imperative to maintain adequate water levels in these wetlands during these crucial months for the benefit of the northward migrating waterbirds. During the study period, it was also found that activities like road building could have had a deleterious effect on the number of birds that used this wetland. We recommend that similar studies be carried out in some of the adjoining wetlands of the area in a synchronous manner to further understand the subtlety of local avian movements within the greater Coimbatore area.
