Description

Habitat

Vegetation: freshwater marshes, pelagic waters • Foraging Strata: Water • Center of Abundance: Lower tropical: lowlands, lower than 500 m.; tropics. • Sensitivity to Disturbance: High

Typically found at an altitude of 0 to 3,422 meters (0 to 11,227 feet).[1]

Ecology: Breeds in rock crevices and burrows in colonies on offshore islands. The breeding season is protracted, and eggs are laid asynchronously, with some pairs laying eggs while other pairs are in the midst of chick-rearing. At Southeast Farallon Island, Ashy Storm-petrels visit the colony year-round, and most breeding activity is concentrated in February through October7. At Santa Cruz Island, Ashy Storm-petrel nesting activity spans March through December6,8. Birds feed at sea on planktonic crustaceans and small fish and visit the colony at night. Foraging during the breeding season occurs mainly over continental shelves (92 - 98%), with aggregations coinciding spatially and seasonally with the spawning aggregations of sardines and anchovies14.
