WERC Seabird Biologists on False Klamath Rock

USGS biologists with the Western Ecological Research Center (WERC) climb the upper slopes of False Klamath Rock, off the California coast. They are deploying acoustic monitoring devices near the nests of Ashy Storm-Petrels, an elusive, nocturnal seabird known to nest only on offshore rocks and islands throughout California and northern Baja California, Mexico. The scientists’ goal is to learn...

Fresh Storm-Petrel Nesting Burrow

Fresh excavation of a storm-petrel nesting burrow on an island in Humboldt County. Note the fresh dirt that has been scraped by the bird onto grass in front of the burrow entrance. Storm-petrels only visit these secretive sites nocturnally and are very difficult to monitor or study, which is why USGS biologists are using acoustic monitoring technology to detect storm-petrel vocalizations at...

WERC Wildlife Biologist Climbs Offshore Islet

USGS wildlife biologist Emma Kelsey searches for potential Ashy storm-petrel nesting habitat on Piedras Blancas rock, off the California coast. Ashy storm-petrels make their home in burrows and crevices on offshore rocks and islands, and only enter and leave nests under the cover of darkness. USGS scientists are using passive acoustic monitors to record Storm-petrel calls as they return to...
