Late-stage granulomatous interstitial pneumonia secondary to near-drowning in an osprey (Pandion haliaetus)

This report describes case management of a granulomatous pneumonia occurring in an osprey (Pandion haliaetus) after a neardrowning incident. The bird initially responded to aggressive antimicrobial therapy, but was euthanized after 26 days due to severe pulmonary hemorrhage. Necropsy revealed the source of the hemorrhage to be a multifocal granulomatous and heterophilic interstitial pneumonia affecting 30% of the lungs. The bird was cachectic on presentation and required aggressive nutritional support. A major achievement of this case was to stimulate an osprey to eat on its own in captivity by using live fish.
