Like mother like daughter: northern elephant seals exhibit fine-scale philopatry.

ABSTRACT: Natal philopatry, the practice of a mother reproducing in the same region as her natal site, has been documented in numerous species. Studies on marine mammal philopatry have primarily focused on cross-colony scales, leaving a knowledge gap for fine-scale philopatry within colonies. We sought to identify the rate of fine-scale natal philopatry in northern elephant seals, sustained site fidelity across years, and additional drivers of site selection during the breeding season. Using 20 years of mark-recapture data collected from the ~3200-m long Año Nuevo colony in northern California, we discovered high rates of fine-scale philopatry, with females pupping an average of 395 m from where they were born. Females producing pups showed high site fidelity to the site of their first pup productio
