Which disease is commonly associated with pigeons?

• A. Avian influenza
• B. Newcastle disease
• C. Coccidiosis
• D. Frounce

Answer: (D)

Pigeons are most characteristically affected by frounce, a protozoal infection of the mouth and upper digestive tract. It causes yellowish, cheesy plaques in the mouth and throat that can extend into the crop, often leading to drooling, foul breath, and reduced feeding. The disease spreads readily in crowded or flock settings through contaminated feed, water, or direct contact, making it a common concern for both captive and racing pigeons.

Avian influenza and Newcastle disease are viral illnesses that can infect many bird species, not just pigeons, so they aren’t as specifically associated with pigeons. Coccidiosis is a gut parasite that can affect various birds as well, though it’s less uniquely linked to pigeons than frounce. Recognizing the characteristic mouth lesions and understanding transmission helps pinpoint frounce as the pigeon-associated disease. Treatment and control should be guided by a veterinarian, with attention to sanitation and flock management to prevent spread.
