Hypothesized reconstruction of the Trichomonas-like infection of the oropharynx and mandible of MOR 980, commonly known as ‘Peck's Rex’

Note the yellowing of the oropharyngeal area at the back of the mouth and developed lesions within the mandible that penetrate the full thickness of the bone. This reconstruction is based on photographs of living birds and bird necropsies of individuals with trichomonosis.
