Delhi’s Sir Ganga Ram Hospital has found a strong link between prolonged exposure to pigeons and serious lung diseases.

If there is one bird that has dominated the urban landscape in recent years, it’s pigeons. City squares, roadside patches, and community spaces have transformed into pigeon feeding grounds, leading to a population explosion. While feeding these birds is seen as an act of compassion, many people are unaware that pigeons pose serious health risks.

Pigeons leave behind a trail of feathers and droppings, which causes real harm. These can carry fungal, bacterial, and parasitic infections, which may trigger allergic reactions, and even lead to serious lung diseases. According to research by Delhi’s Sir Ganga Ram Hospital, prolonged exposure to pigeons can have severe health consequences. Studies have also linked frequent feeding and proximity to these birds to increased health risks.

Health Risks Of Pigeon Feeding

Pigeon droppings may appear innocuous, but they can harbour harmful fungi like Aspergillus. When inhaled, these fungi can cause Histoplasmosis, leading to serious lung conditions such as Bird Breeder’s Lung (Hypersensitivity Pneumonitis). This may trigger an immune response, causing inflammation in the lungs’ interstitium, which is crucial for oxygen exchange.

If left untreated or diagnosed late, Hypersensitivity Pneumonitis can progress to irreversible lung fibrosis, severely impairing respiratory function. However, early detection within six weeks of symptom onset can often reverse the condition with treatment. It’s essential to be aware of the risks associated with pigeon droppings to prevent long-term damage.

How To Protect Yourself?

Pulmonologists strongly advise residents to pigeon-proof their balconies and surrounding areas. In Mumbai, many Resident Welfare Associations (RWAs) have taken proactive steps to cover balconies and eliminate potential breeding spots, setting a great example for others to follow.

You can also follow these steps to eliminate potential risks.

Don’t Feed Pigeons: Feeding attracts more pigeons, increasing population and exposure risks.

Seal Windows And Balconies: Install nets or mesh screens to keep pigeons out and keep areas clean.

Wear Protective Gear: Use an N95 mask and gloves when cleaning pigeon droppings to avoid inhaling harmful particles.

Use Deterrents Like Tape: Spike strips, reflective tape, or ultrasonic repellents can prevent pigeons from roosting.

Disinfect Regularly: Clean surfaces with bleach or strong disinfectants to eliminate pigeon droppings and bacteria.

Check Hidden Areas: Check building ducts, water tanks, and other hidden spots for pigeon nests and seal any openings.
