This study aimed to describe the anatomical specificities and morphometric values of the quadrate bone of two species of psittacines. Were used the quadrate bones of twenty specimens of Amazona aestiva and three specimens of Diopsittaca nobilis donated for studies by the Paraíba Wild Animal Triage Center (CETAS-PB)/IBAMA. The bones presented similar characteristics, having the same crests and depressions. The results obtained provide data that may assist the veterinarian in better understanding the anatomy of this essential bone for craniocinesis.
