The population of house sparrows (Passer domesticus) in India has shown a declining trend in recent decades. In many places like Punjab, Haryana, West Bengal, Bangalore etc a very sharp decline has been observed by ornithologist. The species has shown a conservation concern in its native ranges. According to a recent study by Indian Council of Agricultural Research (ICAR) the house Sparrow population in Andhra Pradesh has reduced up to 88% and in other states like Kerala, Gujarat, Rajasthan it has dropped down up to 20%. In coastal areas of India the population has tremendously dropped to 70 to 80%. The main cause of decline of this species remains unidentified but it is believed the unavailability of nests because of modernization, constructions, and deforestation can lead to their decline. The other causes might also include rapid use of insecticides, competition with other species etc. Modern houses do not leave any space for the species to build their nests but in past few years artificial nest boxes are promoted like wooden nest boxes, shoes boxes as nests or earthen pots as nests, which give house sparrows an alternative to live in.
