The article highlights the sharp decline of house sparrows across urban India and globally, pointing to changing city environments as the primary cause.

Once a common presence in homes and neighbourhoods, sparrows are now disappearing from modern cities due to loss of nesting spaces, reduced food sources, and environmental changes.

Traditional buildings with ventilators, tiled roofs, and small crevices provided ideal nesting conditions, but contemporary glass-and-concrete structures are sealed and inhospitable.Urban landscaping has also eliminated hedges, mud patches, and open water sources that sparrows depend on.Food scarcity is another major factor.Sparrows rely on seeds and insects, especially to feed their chicks.However, increased pesticide use and cleaner, sanitised urban spaces have drastically reduced insect populations.Air pollution and possible effects of unleaded fuel byproducts further impact their survival.Additionally, competition from pigeons, crows, and invasive species, along with predation by cats, has made urban environments more hostile.

Despite the decline, sparrows continue to survive in older, densely built neighbourhoods where mixed-use spaces and less manicured surroundings still support biodiversity.The article emphasises that sparrows are ecologically important, helping control pests and potentially reducing disease transmission risks.Encouragingly, several grassroots initiatives across Indian cities are showing positive results.

Campaigns in Hyderabad, Mumbai, Chennai, and Mysuru have introduced nest boxes, feeders, and awareness programmes, leading to a gradual return of sparrows.

Experts suggest simple actions such as installing nest boxes, leaving water and food, planting native vegetation, and allowing some natural, unmanicured spaces.

The broader message is that small, conscious changes in urban planning and individual behaviour can help restore habitats and bring sparrows back into daily life.
