World Sparrow Day is being observed worldwide today, marking an annual effort to raise awareness about the rapid decline in sparrow populations. Celebrated every year on March 20, the day was first observed in 2010 across various parts of the world. This day emphasizes the effects of urbanization, pollution, and habitat destruction on these small birds. Sparrows play a vital role in maintaining ecological balance by controlling insect populations and supporting plant pollination. Conservation measures, such as setting up bird feeders, planting native vegetation, and minimizing pesticide use, can aid in their protection and ensure a healthier environment for urban wildlife.
