During the period mentioned above (200-2004) the house sparrows usually tried to enter the house and build their nests inside the house, typically above the fans or inside the lofts. But in past 3-5 years the sighting of these sparrows have decreased drastically. One would be lucky to find these sparrows. There might be few reasons associated with this change, such as 1. Less open grassland (trees, shrubs, plants) 2. Better sealed building envelopes which resists birds entrance inside ones home 3. Scarce food available for these birds.
