Mining social networks to track the irruption of a boreal seabird in the Mediterranean

In an era of rapid climate and environmental changes, reporting on uncommon wide-range animal movements may help to depict potential carry-over effects at the population level. In winter 2022-2023, a typical seabird of the North Atlantic, the razorbill Alca torda, irrupted in unusual large numbers in the Mediterranean. Mining social networks, we estimated the spatio-temporal progression of the irruption event and reported first data on the foraging habits of razorbills, at regional level.
