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.

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.
