Résumé :	We tested endogenous migratory fuelling and nocturnal migratory restlessness in juvenile Northern Wheatears (Oenanthe oenanthe) from Alaska kept in captivity indoors. The birds showed a spontaneous seasonal, and biologically relevant, pattern of body mass development and nocturnal migratory restlessness. These data were compared to similar data of Northern Wheatears from Iceland. The Alaskan birds showed much higher restlessness but lower fuelling, which is consistent with their much longer journey but different ecological encounters.
