Population Size of House Sparrow (Passer domesticus) and Stress Factors Affecting Its Numbers in Selected Habitats in Thanesar, Kurukshetra District, Haryana, India

This study investigates the population dynamics of the House Sparrow (Passer domesticus) in various habitats within Thanesar, Kurukshetra District, Haryana, India, over a two-year period from 2010 to 2011. The research focused on three main habitats: rural open areas, warehouse environments, and agricultural fields. Population counts were conducted monthly, revealing significant variations in sparrow numbers across different environments and years. In rural open areas, a considerable number of adult males, females, and young sparrows were observed, while warehouses showed significantly lower populations. Agricultural fields also exhibited reduced sparrow numbers compared to rural open areas. The study highlights the impact of habitat type and potential stress factors, such as urbanization and agricultural practices, on sparrow populations. Understanding these dynamics is essential for developing conservation strategies to protect this once-common urban bird.
