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 success is clearly important reproductive success, it might equally that mate has a complementary strategy. We test whether partners have similar or dissimilar strategies where both share responsibilities exhibit fidelity (thick‐billed murre; Uria lomvia ). To examine thick‐billed murres showed strategies, we attached GPS accelerometers within 40 murre chick‐rearing pairs. Individuals pair were their trip distance number dives during trips compared randomized Breeding also more wing length than This result could related individual quality as individuals select sized sites lead partners. conclude strategy diversity maintained this population either because prefer own, diverge over multiple season together.
