The authors tracked the movements of 30 birds, including Eric the seagull, using solar-powered GPS units in real-time. The study focuses on Eric's life, a male Lesser Black-backed Gull breeding in Zeebrugge colony, over two months. CartoDB technologies were used to create interactive maps and analyze Eric's movement patterns, providing insights into his daily habits. The authors also made the data available under Creative Commons, allowing others to explore and build upon their work.
