Pigeons linked to rising lung ailments in cities

Urban landscapes across the world are witnessing a silent health challenge linked to a familiar bird: the pigeon. While pigeons have adapted well to city life and often symbolize urban resilience, recent studies suggest their presence may be contributing to a rise in respiratory problems among city dwellers.

Pigeons shed microscopic feathers, dried droppings, and dust laden with fungal spores. When inhaled, these particles can irritate the lungs and, over time, cause conditions such as allergic alveolitis, hypersensitivity pneumonitis, and chronic bronchitis. 

Doctors in major cities like Mumbai, London, and New York have reported an increase in patients with unexplained shortness of breath and lung scarring—symptoms often traced back to prolonged exposure to pigeon droppings and nesting areas.

The problem is compounded in dense urban environments where ventilation is poor and pigeons roost in high numbers on residential balconies, office buildings, and public spaces. Vulnerable groups, including children, the elderly, and those with pre-existing asthma or weakened immunity, face the highest risks.

Experts emphasize that the issue is not with pigeons alone but with unchecked urban proliferation and human tolerance of their presence. Preventive steps—such as discouraging feeding, installing bird deterrents, and ensuring regular cleaning of roosting areas—can reduce exposure to harmful allergens.

As cities grow, balancing compassion for urban wildlife with public health priorities becomes critical. Without awareness and intervention, the humble pigeon may continue to quietly impact the respiratory health of millions living in crowded metropolitan areas.
