“Researchers have suggested that cockatiels may be predisposed to bacteria-related lockjaw because of an unusual cranial air sac or nasal sinus conformation through which an upper respiratory infection can easily disseminate to adjacent muscles, nerves, or joints. An alternative hypothesis was that young cockatiels have weaker local immune responses in their nasal passages than other young psittacine species.”
