Why sparrows are decreasing in India?

Factors like urbanisation, replacement of ventilators with air conditioners in houses, radiation from mobile towers, pollution, use of insecticides and pesticides in farms and emission of harmful gases are considered the main reasons that led to a drastic decline in the population of sparrows.

Why are songbirds declining?

Other possible explanations of declines in eastern migratory songbirds have to do with changes within North America. They include increased cowbird parasitism, loss and fragmentation of habitat, and increased nest predation in habitat patches.

Sparrows, though tiny, are very sensitive and strongly immune birds, and their sudden disappearance as sentinels or as ecological indicators is a warning to humans about impending environmental hazards.

Why do sparrows fly away from humans?

Above all, the recent increase in electromagnetic radiations from cell phone towers outdoors and the explosive use of diverse wireless devices indoors have also chased away the birds. It could be the synergistic effect of all these environmental pollutants that has compelled sparrows to fly away from their long-trusted human companions.
