Journal of Anatomy
The greater rhea (Rhea americana) is the largest bird in South America. It is flightless and cursorial, with a precocial postnatal development. This study aims to describe the postnatal morphological changes in the pelvic girdle of Rhea americana ...

Veterinary Parasitology: Regional Studies and Reports
The larval chigger mite Apolonia tigipioensis Torres and Braga is an obligatory hypodermic parasite found in South America. Its parasitism can significantly affect the host's health, leading to nodular lesions that consequently result in the host's death.

Light and Scanning Electron Microcopy Study of the Tongue inRhea americana [PDF]
Zoological Science, 2011 Morphological characteristics of the tongue were studied in adult rhea (Rhea americana). The lingual surface and the surface of epithelium-connective tissue interface of rhea tongue were examined macroscopically and by light and scanning electron ...

Multiple Intussusceptions in a Juvenile Rhea (Rhea americana) with Proventricular Impaction
Avian Diseases, 1997Multiple intussusceptions of the small intestine were identified in a 4-mo-old rhea (Rhea americana) that died acutely after chronically poor growth. The chick was one of a group of 12 chicks that exhibited musculoskeletal deformities, poor growth, and subsequent death.

1973
The karyotypes were prepared from feather pulp of specimens obtained from the Como Zoo, St. Paul, Minnesota. Takagi et al. describe a slightly hetromorphic acrocentric pair (Z and W) which they assign to size six position.

Chronic fascioliasis in farmed and wild greater rheas (Rhea americana)
Veterinary Parasitology, 2007From 50 farmed Rhea americana slaughtered for human consumption, adult forms and eggs of Fasciola hepatica were found in 4. The other three livers were free of flukes but did show lesions caused by larval fluke migration. Histological lesions were similar to those caused by flukes in cattle and sheep.

Identification of the swine pathogen Serpulina hyodysenteriae in rheas (Rhea americana)
Veterinary Microbiology, 1996Recently intestinal spirochetes were isolated from rheas in Ohio and Iowa with a necrotizing typhlocolitis. These intestinal spirochetes, strains R1 and NIV-1, were characterized and compared with other intestinal spirochetes, including strains of S. hyodysenteriae. Both rhea spirochetes were indole positive, strongly beta-hemolytic, grew under a 1% O2:

Intestinal Smooth Muscle Hyperplasia in a Rhea (Rhea americana)
Avian Diseases, 1995Smooth muscle hyperplasia of the small intestine occurred in an 18-month-old rhea (Rhea americana). The mucosal thickening was 2-3 mm, and the enlarged muscle layers averaged 5 mm thick. The intestinal villi were lengthened, pleated, and expanded by smooth muscle hyperplasia within the lamina propria.

Ontogeny of feeding and drinking in the greater rhea (Rhea americana)
Behavioural Processes, 1978Feeding and drinking movements of the greater rhea chick are analyzed. Feeding consists of five movements in the following sequence: orientation, pecking thrust, head lift, forward head jerk and swallow. Drinking is less complex, consisting of a downward movement followed by an upward movement.
