Which environmental condition increases the risk of aspergillosis in captive birds?

• A. Dry, dust-free air
• B. Cool temperatures
• C. Damp organic material
• D. Bright light

Answer: (C)

Aspergillosis in captive birds is driven by inhaling mold spores that thrive on damp organic material. Wet litter, spoiled feed, and decaying plant matter in poorly ventilated aviaries provide ideal conditions for mold to grow and release spores into the air the birds breathe, increasing infection risk. Dry, well-ventilated environments reduce exposure, while bright light or cooler temperatures don’t promote mold growth as much. Keeping bedding dry, removing damp material promptly, and ensuring good ventilation lowers the risk.
