Abstract

A brief study is conducted in Jamakhandi town which possesses both urban and rural traits to understand the population trends of house sparrow, Passer domesticus L, for a period of six months. The current study area is divided into four parts of the town viz,. Rural East, Rural West and Urban East, Urban West.
