Within-pair similarity in migration route and female winter foraging effort predict pair breeding performance in a monogamous seabird
In long-lived monogamous animals, pair bond strength and durability are usually associated with higher fitness. However, whether pairs maximise fitness during the non-breeding season by maintaining contact during the winter or, instead, prioritise individual condition is unclear. Using geolocators r...

In long-lived monogamous animals, pair bond strength and durability are usually associated with higher fitness.
