Question

List the possible reasons for decline in the sparrow population

Answer 1

• Sparrows are social birds and are very closely associated with the habitation of humans. The rapid changing cities are making difficult for the birds to survive.
• They usually build nest on the roofs of the houses. The modern infrastructure of the building are not accommodating the nests of the birds.
• The change in the city structure and infrastructure majorly depends on the population levels. Thus, rise in population is also a cause of reduction in sparrows.
• The microwaves from the towers affect the brain of the birds and they drop dead instantly.
• The pesticides in the plants and water made the survival of the sparrow difficult.
