Abstract: Lay Summary Migrating birds regularly perform long continuous flights lasting several days, but what compass mechanism they use is still a mystery. Here, we apply an individual-based model, taking compass mechanisms based on celestial and geomagnetic information and wind into account simultaneously, to investigate what compass is used during continuous migrations. We found that wind compensation and a magnetoclinic route, based on detection of the angle of inclination during migration flights, were most likely used.Twitter: @Susanne_Akesson
