| Abstract | Migratory behaviour in young individuals is probablydeveloped by using a complex suite of resources, frommolecular information to social learning. Comparing themigration of adults and juveniles provides insights into thepossible contribution of those developmental factors tothe ontogeny of migration. We show that, like adults, juve?nile Icelandic Whimbrel Numenius phaeopus islandicus flynon-stop to West Africa, but on average depart later, fol?low less straight paths and stop more after reaching land,resulting in slower travel speeds. We argue how the varia?tion in departure dates, the geographical location of Ice?land and the annual migration routine of this populationmake it a good model to study the ontogeny of migration. |
