The emu ( Dromaius novaehollandiae ) now belongs to a monotypic genus, because the other two species, D. ater and D. baudinianus , which were smaller (the size of a bustard) and lived, respectively, on Kangaroo and King islands, were exterminated by humans in the early 19th century.

RETROSPECTIVE STUDY OF MORTALITY IN CAPTIVE STRUTHIONIFORMES IN A FRENCH ZOO (1974–2015)
Journal of Zoo and Wildlife Medicine, 2018The husbandry and medical records, and necropsy reports, of 1,002 captive Struthioniformes that died at the Réserve Africaine de Sigean (France) from 1974 to 2015 were examined. The goal of this study was to determine the most common causes of mortality in ostriches ( Struthio camelus), emus ( Dromaius novaehollandiae), and American rheas ( Rhea ...

Ordnung: Struthioniformes – Flachbrustvögel
2020Die Ordnung der Flachbrustvogel umfasst Vogelvertreter ohne Flugfahigkeit (Ausnahme Steishuhner) mit teils wenig oder sehr stark reduzierten Flugeln, kraftigen Laufbeinen und oft reduzierten und krallenbesetzten Zehen. Bei den Strausen sind lediglich 2 Zehen vorhanden, wahrend Kiwis noch 4 tragen.

The genus Libyostrongylus includes three species, L. douglassii, L. dentatus and L. magnus that occur as parasites in the proventriculus of Struthio camelus. We confirmed a mixed infection by L. douglassii and L. dentatus in farmed ostriches from the southeast of Brazil for the first time, and provided new information on some morphological characters ...

Codiostomum struthionis is a nematode parasite of the ostrich caecum. Little is known about its pathology, being considered by many authors as a non-pathogenic parasite. Infections by C. struthionis are sometimes overlooked because its eggs are indistinguishable from another ostrich nematode, Libyostrongylus spp.

The bursa cloacae (Fabricii) of struthioniforms in comparison with the bursa of other birds
Journal of Morphology, 1982AbstractThe late embryonic and postembryonic genesis of the bursa cloacae (Fabricii) of struthioniforms and other birds is described and discussed. The bursa of ostrich and emu is a wall organ of the caudal cloacal chamber. The bursa of rhea is, like the bursa of Gallus, a cranial appendix of the proctodeum.

Emus provide an excellent opportunity for studying sustained high-speed running by a bird. Their pelvic limb musculature is described in detail and morphological features characteristic of a cursorial lifestyle are identified. Several anatomical features of the pelvic limb reflect the emus' ability for sustained running at high speeds: (1) emus have a ...

AbstractA new species of mite from the family Analgidae, Megninia casuaricola sp. n., is described from the feathers of a southern cassowary, Casuarius casuarius (L.). Until now, cassowaries were among the few terrestrial birds thought to be without feather mites. The new species of mite is readily distinguished from other described species of Megninia
