Fine keratin particles produced by specialized feathers in many parrot species (Cockatoos, African Greys, Cockatiels). Powder down coats contour feathers for waterproofing and gives parrots their characteristic dusty appearance.
Heavy powder down production requires regular bathing and air filtration. It can aggravate allergies in sensitive owners.
Mist or bathe powder-down species 2–3 times weekly. HEPA air filters significantly reduce household dust from Cockatoos and African Greys.
