The study carried out and the data collected are a contribution to questions about the values of subsequent vertebrae in the spine of birds belonging to the subclass Palaeognathae. The methods used for measuring the metric traits of cervical vertebrae and the results obtained can also support and complement studies on bone mineral concentration (BMC - insufficient content of minerals in the bone tissue) and bone density (BMD - improper mineral density) in the birds being kept under industrial conditions and seasonally affected by the laying (Kim et al, 2006; Dzierze.cka & Charuta, 2010) and exposed particularly during this period to calcium-phosphate imbalance.
Whether ETHBV can infect other species within the Palaeognathae or whether it is host restricted within other tinamou species remains to be elucidated.
Elegant-crested tinamou (Eudromia elegans) belong to the family Tinamidae, which includes 47 species and 9 genera of birds native to Central and South America, and are related to ratites under the superorder Palaeognathae. (1) Elegant-crested tinamou is the most common captively held tinamou species in North America.
