This activity is undertaken to raise awareness of the declining number of house sparrow in India especially in metro stations and the need for its conservation. Trying to preserve the existing populations and undertake measures to raise their numbers within the area. About 15 years ago the house sparrow was one of the most common bird to be seen. The house sparrow population in declining fast. Food supplies in the metro stations have been reduced with the development of new buildings. House sparrows need aphids, weevils, grasshoppers and caterpillars to feed their young and these may now be harder to find in metro stations. The intensified use of pesticides and herbicides which reduces the amount of insects and weed seed food, changes in agricultural practices. Reduction in the availability of nest sites through the renovation of old buildings, and modern architectural designs, especially roofs with a reduction in access to roof space, clearance of shrubberies in parks and removal of creepers from wall. Finally the effect of predation by sparrow hawks, crows, and the domestic cat. All these factors have considerably reduced population of Indian house sparrows.
