Abstract

The research reported here, conducted at Archipiélago de Espíritu Santo National Park, Baja California Sur, Mexico, establishes the first successful application of biologging on a Black Storm Petrel Hydrobates melania. Results yielded preliminary insights into this population's marine movements during nesting. The device used, weighing less than 3% of the bird's body mass, recorded a 181-km foraging trip. Subsequent trajectory analysis indicated navigation behavior that potentially was optimized to use crosswind assistance. The individual showed no weight loss post-retrieval, a finding that suggests this method is viable and unharmful, demonstrating the feasibility of using miniaturized tracking devices to unravel the ecology of this elusive seabird.
