Genetic ancestry plays a key role in the migration of Cory's shearwaters

To what extent do genes influence the migratory routes of birds? The factors that determine the long-distance migrations of seabirds are not yet fully understood. Now, a study published in the journal Molecular Ecology reveals that, in the case of Cory's shearwater, an individual

To what extent do genes influence the migratory routes of birds? The factors that determine the long-distance migrations of seabirds are not yet fully understood. Now, a study published in the journal Molecular Ecology reveals that, in the case of Cory's shearwater, an individual's genetic ancestry is a more significant factor in their migratory decisions than their social environment in the breeding colony.
