Resumo
Traumatic injuries are a significant cause of death for birds worldwide, as they are at an increased risk of collisions and other injuries due to man-made environments. This study examined the frequency and morphological characteristics of fatal traumatic injuries in endemic and migratory Passeriformes and Psittaciformes from the Cerrado Biome, a biodiverse but threatened area in Brazil. Results showed that fatal traumatic injuries were found in 21.8% of birds (285/1305), mainly in spring and summer, during the birds’ reproductive period. The yellow-chevroned parakeet (Brotogeris chiriri) and Passeriformes from the Thraupidae family were the most affected. Nearly 70% of the fatal injuries observed were to the thoracic, pelvic limbs, and skull, and types of fractures and affected bones were thoroughly evaluated. Blunt traumas were one of the most frequent causes of injuries. Injuries affecting the appendicular skeleton and head represented significant causes of traumatic death for Passeriformes and Psittaciformes. The frequency of these fatal injuries has been increasing in recent years, which may be related to the remarkable environmental changes in the Cerrado Biome and jeopardize the survival of many bird species.
