Abstract

Obtaining craniometric data is key to establishing parameters that can help in the anatomic identification and understanding of species. The aim of the present study was to establish the craniometric data and describe the main skull bones and structures of Amazona aestiva, which has become common in veterinary clinics, originated from the legalized purchase or trafficking of animals. A total of 20 adult specimens were used, donated for studies by the Paraíba Wild Animal Screening Center (Centro de Triagem de Animais Silvestres da Paraíba (CETAS-PB)/IBAMA-PB, Brazil. The skulls were dissected and macerated with water. First were identified the frontal, maxilla, mandible, nasal, jugal and quadrate bones that served as a base to identify other bone structures that were then compared with the skull of other bird species already described in the literature, especially psitacids. Values were obtained by measuring with a digital pachymeter, and the maximum skull length was 63.0 mm, the maximum width 33.0 mm and the rhamphotheca was 33.8 mm long. No significant differences were observed between males and females and well developed cranial kinesis was a remarkable characteristic of the species. The data obtained serve as a base to identify and characterize the species. These data can also aid in the clinic, imaging and veterinary surgery.
