Preliminary observations on the food preference of bird’s inhibiting in various cropland system of Tandojam

Passeriformes bird’s are generally regarded as insectivorous bird’s. These avian predators play paramount role to control the insect pest population form different cropland and forest ecosystem. Bird population occurring in the croplands of Tandojam during the year 2015 was pertaining to order Passeriformes including Common Babbler, Common Myna, House Sparrow, Indian Wren Warbler, Jungle Babbler, Rosy Pastor, Yellow throated Sparrow, Common Wood Shrike, Gray Wagtail and Crow were mainly insectivorous, whereas, Pigeon and Parrot belong to Columbiformes and Psittaciformes found occasional insectivorous. Beside this, status of 9 bird species were resident and only 3 species i.e Rosy Pastor, Grey wagtail and Yellow throated Sparrow were migrant in nature. Among the most dominant bird species, the Jungle Babbler and Common Myna were of significantly important, they exclusively derived their food from insect source. It was observed that insect based food was dominated by the order Hymenoptera compose on ants and thin larvae and wasps and their larvae, Hemiptera comprise on bugs, scale insects, aphids and lice. This study support to implement conservation tactics to increase the bird populations in different cropland ecosystems where they could function as a biological control agent of insect pests.
