A gradual migratory divide determines not only the direction of migration but also migration strategy of a social migrant bird

The paper uses satellite tracking and Gaussian processes to show a gradual migratory divide in greylag geese that affects migration direction and strategy between flyways.

When and where to count? Implications of migratory connectivity and non-breeding distribution to population censuses in a migratory bird population

The paper tracks migratory birds to assess how migratory connectivity and non-breeding distribution affect census accuracy and population size estimation.
