The Ramsar Convention defines Wetlands as 'areas of marsh, ponds and swamps, whether Materials and Methods natural or artificial, permanent or temporary, Study area with water that is static or flowing, fresh, brackish or salty, including areas of marine The Present study was conducted in Thuraiyur water, the depth of which at low tide does not Lake (Chinna Eri) (Latitude 11° 8'49.78"N and exceed six meters'.

Wetlands are also important for birds, as freshwater lake receives water from Thuraiyur migratory and non-migratory birds depend on big lake located one kilometer north and from the wetland habitat and biodiversity. Wetlands natural rainwater.

The Chinna eri is surrounded by agricultural fields on The wetlands are lands transitional between one side and human settlements on the other terrestrial and aquatic system where the water side. The wetland water quality is highly table is usually at or near the surface, or the land influenced by influx of municipal sewage that is covered by shallow water (Cowardin et al., maintains the water level throughout the year. 1979).

It is essential to understand the causes of decline in populations and to control the changes or prevent the loss of key components of the biodiversity in wetland habitats. Suburban areas represent a middle habitat condition between natural and urban environment which has an ideal potential for sustaining varied avian communities (DeGraff and Wentworth, 1986). Water pollution is one of the major issue of urban wetlands in India due to waste disposal of human activities. In this article Figure 1. Location of the Thuraiyur Lake (Chinna Eri) we attempt to document the avifauna dependent SACON ENVIS Newsletter - Sarovar Saurabh Vol.16(3), 2020. ISSN: 0972-3153 1 Methods dominated the wetland which we attribute to the increased solid waste and pollution load Birds were observed from January 2019 to May corroborating the observations made by Sudha 2019 for a period of five months following line and Sangeetha (2017). We also noticed that the transect method during early morning 7:00 am to wetland had high aggregation of plastic waste 10:00 am as the bird activity was high during this adding to the pollution load and reducing the time of the day (Bibby et al., 1998). During the habitat suitability. field visit photos were taken using Nikon D3300 with zoom lens 55 – 500 mm. Binocular (Olympus 10 x 50) was used to record the observations from the distance in order to avoid any disturbance to birds. The avifauna was identified in the field using Grimmett et al. (2011) and the check list (Table 1) was prepared. The list was categorized as per the IUCN Red list, feeding habits and migratory status. Results and Discussion In total, 64 bird species were observed which Figure 2. Monthly variations in the bird orders belong to 16 orders and 39 families (Table 1).
