Upper Respiratory Tract Infection Caused by Cryptosporidium baileyi in Three Mixed-Bred Falcons (Falco rusticolus × Falco cherrug)
Three mixed-bred raptors (Falco rusticolus × Falco cherrug) from a German falcon breeder were presented with a history of respiratory distress. In one bird a laryngeal stridor was noted, and oral examination revealed an epiglottal swelling. In the other two birds, nasal discharge and sneezing were t...
