José Luis Copete February 23, 2021
New research is challenging the assumption that previous migratory experience is necessary for birds to correct themselves when blown off course during migration. A study of Eurasian Reed Warblers shows birds can use a combination of cues derived from the Earth’s magnetic field to detect a displacement, even if all of these cues are of unfamiliar magnitude.
