People heading to parks and other public places to feed pigeons has become a common sight in cities. However, the unintended consequences of this activity on lung health are often overlooked.

A recent case study by a Delhi hospital discovered the harms of close contact with pigeon feathers, droppings, etc. Research reveals a startling link between urban wildlife, specifically pigeons, and interstitial lung diseases (ILDs). Bird Breeder’s Lung or Hypersensitivity pneumonitis (HP) is one of the most common forms of ILDs that can affect humans feeding pigeons regularly.
In a conversation with mid-day.com, Dr. Lokesh Gutta, Consultant Interventional Pulmonologist, Manipal Hospital, Vijayawada, explains the impact of feeding pigeons on lung health.
“Pigeons can carry various germs that are harmful for respiratory health,” he reveals.
Some of these are:
- Histoplasma capsulatum: A fungus causing histoplasmosis, which can progress to ILD.
- Cryptococcus neoformans: A fungus linked to cryptococcosis, potentially leading to ILD.
- Psittacosis: A bacterial infection causing pneumonia, which can exacerbate existing lung conditions.
He further explains, “When we feed pigeons, we disturb their droppings, releasing spores and bacteria into the air. Inhalation of these pathogens can trigger or worsen ILDs. ILDs encompass a group of disorders characterized by inflammation and scarring in lung tissue.”
Symptoms of ILDs
- Shortness of breath
- Dry cough
- Fatigue
- Chest tightness
Are ILDs only caused by contact with pigeons?
“There are many factors that can lead to ILDs,” says Dr. Gutta.
“These include environmental exposures (e.g., pigeon droppings), genetic predisposition, autoimmune disorders and occupational hazards,” he informs.
Impact of urban wildlife on lung health
Beyond pigeons, close contact with other animals, insects or rodents can also cause respiratory issues.
Dr. Gutta gives the following examples.
- Rodents: They carry allergens and pathogens, exacerbating respiratory issues.
- Cockroaches: They produce allergens and can trigger asthma attacks.
- Mold: It thrives in urban environments, contributing to respiratory problems.
Minimising impact
Follow these tips to minimise the impact of urban wildlife on lung health.
- Avoid feeding pigeons and other urban wildlife.
- Wear masks when cleaning or disturbing areas with potential pathogen presence.
- Maintain good ventilation and air quality in homes and public spaces.
- Support urban planning initiatives prioritising green spaces and wildlife management.
The link between feeding pigeons and interstitial lung diseases highlights the complex interplay between urban wildlife, environment and human health. Recognising these risks and adopting preventive measures can safeguard our lung health while promoting a more harmonious relationship with urban wildlife.
