World Sparrow Day, March 20, was established by the Nature Forever Society in India in collaboration with the Eco-Sys Action Foundation in France and various other national and international organizations throughout the world to promote awareness of the house sparrow and other similar birds. A few years ago, house sparrows were commonly seen in people’s homes.
As a result of rising noise pollution, the bird is now on the edge of extinction. Recent years have witnessed a decline in the number of sparrows in many parts of the world.
Six species of sparrows have been reported from the Indian subcontinent. Out of them, House Sparrow and Eurasian Tree Sparrow are associated with man-made habitats and human activity. Both House Sparrow and Eurasian Tree Sparrow share the same human habitats in many parts of North-East India. These species are closely related and ecologically similar.
