Hemochromatosis was diagnosed at postmortem examination of 5 birds, representing 3 species of lories, including 2 Duyvenbode's lories (Chalcopsitta duivenbodei), 2 black lories (Chalcopsitta atra), and 1 rainbow lory (Trichoglossus haematodus). All 5 birds were housed in the same zoological collection and were fed the same commercially available lory nectar. Classic histopathologic lesions, consistent with hemochromatosis, were observed in all 5 birds. Increased iron concentrations were detected in the nectar diet (1450 ppm) and in the sample of liver (3500–7600 ppm) of affected birds.
