An assessement of bird population in Samathur pond, Pollachi, Tamil Nadu with special reference to feeding guild

  • 1, ,

Birds of Samathur pond, Pollachi were studied from July 2015 to January 2016 by line transect method by marking the
bunds at two opposite ends. Totally of 19300 individuals belonged to 80 species of birds were recorded, which also
included 22 residents, 8 migratory and three near threatened category of birds. More number of species were recorded during November (37), followed by September (36), August (36), October (34), December (32), July (29) and January (22). Number of individuals was recorded high during December followed by November and January. Maximum number of birds was feeding on insects as a major food item. The result showed that among the 80 bird species 22 (28%) were omnivores and 21 (26%) species were insectivore, followed by 11(14%) piscivores, 10(13%) granivores and 7 (9%) carnivores, and others included frugivores and nectarivores that together formed only 11% of occurrence. The difference in richness and diversity between three seasons namely south-west monsoon, north-east monsoon and winter showed greatest difference. A comparative account showed that the individual populations as well as maximum diversity of species were recorded during the southwest monsoon followed by the north-east and winter. (H: SW= 0.4022, NE = 0.1194 and winter = 0.0987) (Hmax: SW = 3.433, NE = 2.152 and winter =1.859).

Keywords: Bird population, carnivores, omnivores, insectivore, piscivores, granivores,frugivores, nectarivores.
