Breeding Partners Have Dissimilar Foraging Strategies in a Long-Lived Arctic Seabird.

ABSTRACT: For long-lived species with biparental care, coordination and compatibility in the foraging behavior of breeding mates may be crucial to successfully raise offspring. While high foraging success is clearly important to reproductive success, it might be equally important that the mate has a complementary foraging strategy. We test whether breeding partners have similar or dissimilar foraging strategies in a species where both partners share breeding responsibilities and exhibit high mate fidelity (thick-billed murre; Uria lomvia). To examine whether thick-billed murres showed complementary in foraging strategies, we attached GPS accelerometers to both partners within 40 thick-billed murre chick-rearing pairs. Individuals within a breeding pair were dissimilar in their foraging trip d
