Which bird is described as carrying respiratory fungal diseases and ectoparasites like mites?

• A. Pigeon
• B. Starling
• C. Canada Goose
• D. Crow

Answer: (A)

Birds that roost in large numbers and leave behind lots of droppings are linked to respiratory fungal infections and ectoparasites. Pigeons fit this pattern in cities and on buildings; their droppings create environments where fungi such as Histoplasma capsulatum and Cryptococcus neoformans can thrive, and when spores become airborne, they can be inhaled and cause respiratory disease in people and animals nearby. Pigeons also host ectoparasites like pigeon mites that live on the birds or in their nests; these mites can drop off and bite humans or spread to pets. Among common urban birds, pigeons are especially associated with these risks because of their abundance and nesting habits in built environments.
