Why Sparrows Are Decreasing in India

Yes, The population of the House Sparrow has reduced a lot in many parts of India, especially in cities and towns. Scientists, bird experts, and environmental groups have reported this decline for many years.
Why Sparrows Are Decreasing in India
1. Modern Buildings
Earlier houses had small holes, roofs, and ventilators where sparrows built nests.
Modern glass buildings and sealed apartments give them very few nesting places.
2. Less Food
Baby sparrows need insects for food.
Because of pesticides and pollution, insects are decreasing, so sparrows struggle to survive.
3. Urbanization
More concrete roads, malls, factories, and fewer trees reduce their natural habitat.
4. Pollution & Radiation
Some studies suggest pollution and mobile tower radiation may also affect sparrows, though scientists are still researching this.
Population Decline in India
Reports mention major declines in several Indian states:
Andhra Pradesh — up to 80–88% decline
Coastal regions — 70–80% decline
Kerala, Gujarat, Rajasthan — noticeable reduction
Compared to Other Countries
In some countries sparrows are still common, especially where:
old-style buildings remain,
green gardens exist,
bird feeders are common,
and pesticide use is lower.
But sparrow decline is also happening in parts of Europe and other regions of the world.
How People in India Are Helping
Many people now:
place water bowls outside,
build wooden nest boxes,
grow plants and trees, and feed grains to sparrows.
Bird 🐦 lovers are also running awareness campaigns to protect sparrows.
