Abstract
The house sparrow, Passer domesticus (Linnaeus, 1758) is closely associated with human habitations and cultivation from historic times. The house sparrow is distributed all over India up to 4000m in the Himalayas. Distribution of House sparrow is not uniform in the country, and in the recent years disappearing of sparrows is also reported from various parts of the world including India. But reliable information on sparrow populations is not available. Less work has been carried out actually for counting and keeping a record of the sparrows. This article summarizes the possible decline in its population through literature review in many parts of the world including India. Several studies carried on house sparrow have cited varied reasons for their decline. So this article also summarized the possible cause and threats for the decline in population. This article compares the role of semi nomadic pastoralist community for conservation of house sparrow with secondary literature. We also tried to suggest the various activities for resolving the issues related with conservation of house sparrow.
