Fig. 1From: Pre-migratory flights in migrant songbirds: the ecological and evolutionary importance of understudied exploratory movementsExploratory movements have been observed in migratory songbirds across the annual cycle. These movement types are found in all age classes. For example, on the breeding grounds, a bird may prospect for extra-pair copulations (EPCs) or prospect other territories to evaluate how successful they have been, while on migration, a bird may explore a stopover site to locate foodBack to article page
