NEW DELHI/MUMBAI: When play was halted twice at the India Open Super 750 in New Delhi after bird droppings fell on the court during H.S. Prannoy’s match against Singapore’s Loh Kean Yew, the moment went viral for its sheer absurdity. But the incident also landed in the middle of a much larger debate playing out across Indian cities: are soaring pigeon populations and the droppings they leave behind becoming an urban management and public health issue that needs regulation, not sentiment?
The Badminton World Federation later responded to player concerns around conditions at the venue, including bird droppings and broader environmental issues, while defending the stadium’s suitability for hosting major events.
A population surge that researchers say is visible nationwide
The core of the “pigeon crisis” argument is a sharp rise in rock pigeon numbers. The State of India’s Birds 2023 report, published by a consortium of Indian research institutions and conservation groups, notes that generalist species are doing well in human-dominated landscapes, explicitly including the feral rock pigeon. Multiple analyses citing the report state that rock pigeon numbers have increased by more than 150% since around 2000, one of the steepest rises recorded among species that are increasing.
Researchers and urban wildlife experts attribute this growth to dense cities creating endless ledges and cavities for nesting, while year-round feeding at specific urban hotspots provides a reliable food source that boosts survival and breeding.
The same report also flags that when a few behaviourally dominant generalists thrive, they can crowd out other species in urban ecosystems, gradually reshaping city biodiversity.
How a cultural practice became a civic enforcement issue
Across cities, the policy response has largely focused on feeding, not culling. In Delhi, the Municipal Corporation of Delhi has in recent years discussed restrictions and advisories around pigeon-feeding hotspots, with officials citing sanitation and respiratory health concerns linked to the concentration of birds.
Mumbai’s conflict has been sharper and increasingly legal. Court proceedings and municipal action around the city’s kabutarkhanas, especially in Dadar, have become a defining case study in how civic bodies balance religious sentiment, heritage arguments, and public health complaints. Bombay High Court records and municipal affidavits have referred to concerns about filth, feathers, and excreta in areas where pigeons congregate in large numbers.
The Brihanmumbai Municipal Corporation has also used sanitation by-laws to penalise feeding in non-designated areas, with media reports noting fines of Rs 500 per violation as part of broader enforcement drives.
The health question, what medicine actually supports
Public health experts stress that the issue is not that pigeons are inherently dangerous. The primary concern is chronic exposure. Droppings can dry, break into fine particles and mix into the air around balconies, air-conditioning units, lofts, and enclosed corners where pigeons roost repeatedly. People living close to heavy roosting sites, cleaners, sanitation workers, and those with weakened immunity are generally considered higher-risk groups.
Medical literature and public health agencies describe several illnesses associated with bird droppings or prolonged bird exposure, though many of these are considered uncommon in the general population.
According to the Mayo Clinic, histoplasmosis is a fungal infection linked to environments contaminated by bird droppings, where spores can become airborne when droppings are disturbed.
The US Centers for Disease Control and Prevention notes that cryptococcosis, another fungal infection, can occur after inhalation of spores found in the environment, including in areas contaminated by bird droppings, particularly affecting people with weakened immune systems.
The CDC also lists psittacosis, a bacterial infection associated with bird exposure, noting that infection can occur through contact with infected birds or contaminated dust. While more commonly linked to parrots, it is included in broader discussions on bird-related zoonotic disease.
Separately, Indian doctors frequently highlight a non-infectious condition that features prominently in urban pigeon debates: hypersensitivity pneumonitis, often referred to as “bird fancier’s lung.” The US National Heart, Lung, and Blood Institute describes it as an immune-mediated lung disease triggered by repeated inhalation of avian proteins from feathers and droppings.
In Mumbai’s case, the health issue has entered formal affidavits and court hearings. In one reported proceeding, Dr Amita Athavale, head of pulmonary medicine at KEM Hospital, was cited as referring to medical literature linking prolonged exposure to pigeon droppings with hypersensitivity pneumonitis and asthma aggravation, while noting that risk assessment requires a multidisciplinary medical approach.
Why the issue is escalating now
What has changed is visibility and volume. Residents’ complaints have expanded from dirty balconies and clogged air-conditioning units to concerns about ventilation shafts, children’s exposure in compact apartments, and sanitation burdens in public spaces. And when bird droppings disrupt a flagship international sports event on live broadcast, the issue moves from neighbourhood grievance to national conversation.
At the same time, municipal and legal actions have triggered backlash. Feeding pigeons is widely seen as an act of compassion in many communities, and attempts to curb it often draw accusations of cultural insensitivity. That tension has led some civic bodies to explore “regulated” or designated feeding approaches rather than blanket bans, though evidence of their effectiveness remains limited.
What experts say needs to happen next
Public health messaging, doctors argue, should remain specific and evidence-based: discouraging concentrated feeding hotspots, preventing roosting in ventilation-heavy building zones, and promoting safe cleaning protocols that reduce dust inhalation. The CDC advises that prevention focuses on limiting the accumulation of bird droppings and avoiding dry sweeping or unprotected cleanup that can aerosolise particles.
For India’s cities, the challenge is not simply “pigeons versus people.” It is governance. A fast-growing urban species, a deeply rooted cultural habit, and densely packed living environments have collided. How courts define public health risk, how consistently civic rules are enforced, and whether cities can move from reactive crackdowns to long-term urban wildlife management will likely determine whether the pigeon debate fades or hardens into a lasting civic fault line.
