A bridled white-eye (Zosterops conspicillata) was captured in a mist net on the island of Saipan and transported to the island of Guam for an experimental study. Beginning on day three, it was immunosuppressed by intramuscular injections of dexamethasone. It was unexpectedly found dead on day 20, at which time it had lost 0.9 g (12.9% of initial body weight). Gross Pathology: Despite the weight loss, the white-eye was in good flesh, with abundant subcutaneous and visceral fat. The spleen was 3 x 11 mm, about 5 times normal size. The striatum of the forebrain was congested. There were no other lesions. Histopathology: There were microscopic abnormalities in skeletal muscle, brain, and gizzard (Figs. 1 and 2; Figure 2 is from a different white-eye which had virtually identical gizzard lesions).
