Abstract: House sparrows are ubiquitous birds, intimately connected with human habitation. These sparrows adapt themselves to the different changes in their habitat, finding their own nesting place and food. According to the recent sparrow census reported in India, there has been 80 percent decline in their numbers during the past decade. Lack of nest sites, food availability, predation was the proposed cause for decline of house sparrows in urban-suburban habitats. Hence this study was done to monitor the habitat preferences of sparrow by observing the number of nests in specific areas i.e., houses, shops, temples, unused wells, electric poles. 168 places in Madurai District were surveyed for the presence of sparrows and their nesting sites. Independent sample t- test was performed to find the level of significance of preference natural and artificial nest of House sparrows. A total of 150 nests was observed in which sparrows were found to show preference to houses and shops than artificial nests.
