Data from: Causes and consequences of partial migration in a passerine bird
Many animal species have populations in which some individuals migrate and others remain on the breeding grounds. This phenomenon is called partial migration. Despite substantial theoretical work, empirical data on causes and consequences of partial migration remain scarce, mainly because of difficu...

Many animal species have populations in which some individuals migrate and others remain on the breeding grounds. This phenomenon is called partial migration.
