This study describes the skeleton of Amazona aestiva parrots and compared it with representatives of other Amazona species. To this end, we used 22 specimens of Amazona aestiva, two specimens each of Amazona vinacea; Amazona rhodocorythae, Amazona farinosa and one specimen each of Amazona brasiliensis and Amazona pretrei donated after natural death by Poços de Caldas Breeding Park. Full body radiographs were taken, in either the right or left lateral decubitus position, in the case of laterolateral projections, and in supine position, in the case of ventrodorsal projection. Regardless of the species, skulls of the parrots were classified as prokinetic, because of free movements in their rostral portion. In most cases, the spine consisted of: 12 cervical vertebrae, six free thoracic vertebrae, synsacrum (formed by the fusion of the last thoracic vertebrae, 7 lumbosacral vertebrae and one caudal vertebrae), five free caudal vertebrae and the pygostyle (formed by three fused caudal vertebrae). Despite punctual differences, thoracic and pelvic appendicular skeleton proved to be very similar to that observed for other genera of birds. In addition, there was no sexual dimorphism considering the anatomical characteristics of the skeletons of parrots analyzed. |
