What aspergillosis is
Aspergillosis ("Asperg" in the parrot community) is a fungal infection caused by inhaled Aspergillus spores — usually A. fumigatus. The fungus colonizes the respiratory tract and air sacs, and in some cases spreads systemically. Birds in stressful environments, with poor nutrition, or kept in damp conditions are at elevated risk.
Species most at risk
African Greys are disproportionately affected — owners learn to watch for it from day one. Macaws, Pionus, and Conures also have elevated risk. See our species pages for African Grey, Macaw, and Pionus-specific guidance.
Symptoms — and why it's caught late
- Voice changes (most common early sign in Greys)
- Tail bobbing during breathing
- Open-mouth breathing
- Lethargy, weight loss
- Decreased vocalization
Birds hide illness. By the time these symptoms appear, the disease is usually well-established. This is exactly why insurance matters — treatment costs are real, and they don't wait.
NYC treatment cost
$800–$3,500+, directional. Initial workup with imaging, bloodwork, and Aspergillus titers runs $400–$900. Antifungal medication (often itraconazole or voriconazole) for a 6–12 week course adds $300–$1,200. Severe cases requiring nebulization, hospitalization, or surgical debridement push the total well above $3,500.
Coverage status
Both Nationwide and MetLife cover aspergillosis as an illness. Standard waiting periods apply (14 days on illness for both carriers). Pre-existing aspergillosis — diagnosed before policy start — is excluded under industry-standard rules.
How to file an aspergillosis claim
- Get a confirmed diagnosis from a certified avian vet
- Submit the full diagnostic record with claim form
- Include all imaging, titer results, and treatment plan
- Save invoices for medications and follow-up visits
Prevention
- Clean cages and food/water dishes daily
- Avoid damp environments and moldy substrates
- Replace HVAC filters regularly; consider HEPA in the bird room
- Quality nutrition supports immune function
- Annual vet checkups with bloodwork after age 5
