Question

how are sparrows getting extinct

Answer 1

Answer:

House Sparrow, once an integral part of our immediate environment, all but disappeared almost two decades ago. The common bird that lived in the cavities of our houses and polished off our leftover food, today sits on the red list of the endangered species of The International Union for Conservation of Nature (IUCN).

• The reasons for the decline of the sparrow population are loss of habitat due to rapid urbanisation, diminishing ecological resources for sustenance, high levels of pollution and emissions from microwave towers.

• “Ventilators in homes have been replaced by ACs and trees by ornamental plants and decorative flower shrubs in parks, making it impossible for the bird to make nests,” explained Khatri.

• Another reason is replacement by other avian species. “The threat is the introduction of other avian species like pigeons with greater reproduction rate and a more generalised need for survival. With pigeons being an invasive species to the sparrow landscape, the competition for resources increased, and pushed the sparrows to degraded and ecologically sub-structured regions of their natural habitat,” explained Saxena.
