Trajectory Analysis of Griffon Vulture in Kvarner Bay
Keywords:Griffon Vultures, trajectories, statistical analysis
Advancements in technology have allowed for detailed tracking of animal movements, revealing the complexity of their behaviour, and aiding in conservation efforts. The study of Griffon Vultures in the Kvarner Bay is a prime example of the importance of trajectory analysis in understanding habitat requirements, migration patterns, and disease surveillance of endangered species. This study helps in analysing their trajectories for better understanding of their behaviour. The results suggest that Griffon Vultures soar in trajectories with low straightness and low velocity which confirms the hypothesis based on their natural movement, mostly for searching for food. Every day approximately 12 hours of data were recorded, and the average distance crossed in one day was 600 meters. The calculated fractal dimension is close to 1, which suggests directed movement towards a clear target.
