## In brief

- A study published in the journal Molecular Ecology reports that genetic ancestry plays a key role in the migration of Cory's shearwaters.
- The factors behind the long-distance migrations of seabirds are not yet fully understood, and the study examines the genetic side of this question.

## Why it matters

Showing that genetic ancestry shapes migratory routes in a seabird helps explain how long-distance migration patterns are inherited and could inform conservation planning for migratory species.
