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.
