Patrones comportamentales y detección de causas de mortalidad en águila perdicera (Aquila fasciata) a través del acelerómetro triaxial de emisores GPS-GSM (Iglesias-Lebrija et al., 2023).
The accelerometer of GPS transmitters is a very useful tool for inferring behavioral patterns in wildlife. One of the most interesting applications in endangered species is to determine their causes of mortality. Most GPS-GSM devices for wildlife tracking currently incorporate an acceleration meter in the three axes of space, called accelerometer, which allows the interpretation of changes in the animal`s position at any given moment. In this study we used Bonelli`s eagle specimens in captivity (n=4) and in the wild (n=72) equipped with GPS-GSM transmitters using Ornitela thoracic harnesses and the OT-30 model to remotely infer behaviors by interpreting the accelerometry graphs. The results show that the information provided by the “x” axis in the balanced position of the transmitter, the “y” axis in the forward rolls and the “z” axis that complements the previous ones, allow a quick visual interpretation of basic behaviors such as feeding, flight, territorial fights, resting, incubation, or chick fattening. But it becomes very important in determining the cause of death, especially in endangered species, which can have legal repercussions in the case of criminal convictions.
