Species within the Aspergillus viridinutans complex are being increasingly recognized as pathogens of animals and humans. An orange-winged Amazon parrot (Amazona amazonica) was referred for a 6 month-history of a slowly developing swelling involving the right nostril. Abnormal physical exam findings included a mild firm swelling at the dorsolateral aspect of the right nostril with no nasal discharge. Computed tomographic examination showed mild deformation of the right naris and nasal conchae without distinct granuloma. A cryptic Aspergillus species in Aspergillus section Fumigati was cultivated and identified by PCR and comparative sequence analysis as Aspergillus pseudoviridinutans. Successful treatment was achieved using topical clotrimazole and systemic antifungals (itraconazole, terbinafine). This is the first report of A. pseudoviridinutans infection in a bird.
