Science and Products
Marbled Murrelet Surveys off the Central California Coast
Since 2017, the U.S. Geological Survey Western Ecological Research Center has continued long-term at-sea surveys of federally threatened Marbled Murrelets in central California.
Assessing Mammalian Predator Control to Protect Endangered Birds at Haleakalā National Park
USGS researchers assessed trends in non-native mammalian predator trapping methods designed to protect endangered ʻuaʻu and nēnē at Haleakalā National Park, Hawaiʻi.
Seabird Vulnerability Assessment for Renewable Energy Projects
The WERC seabird studies team has developed a new framework for quantifying seabird species vulnerability to wind infrastructure in the California Current region of the Pacific Outer Continental Shelf. This tool supports marine resource-use planning by identifying sites where seabirds are most vulnerable and predicts how different species may be affected by wind-energy infrastructure.
Aerial Seabird and Marine Mammal Surveys
The Seabird Studies Team at the USGS Western Ecological Research Center is conducting aerial photographic surveys of the ocean off central and southern California to create comprehensive maps of seabird and marine mammal distributions. The project is supported by the Bureau of Ocean Energy Management and will inform planning in advance of potential offshore wind energy development along the...
Breeding Seabirds of the Main Hawaiian Islands
The seabird research team at the USGS Western Ecological Research Center is working with many partners to map the terrestrial and marine distributions of breeding seabirds of the main Hawaiian islands.
Ashy Storm-Petrel Range and Colony Attendance Behavior
Together with Federal and non-profit partners, WERC's Josh Adams and team are using cutting-edge technology to study the range and population attendance patterns of the Ashy Storm-petrel, an elusive seabird found throughout a large portion of the California Coastal National Monument. Their research will inform management and conservation for this species and other seabirds that use California’...
Seabird Health and Adaptive Management
Dr. Josh Adams and his science team at WERC study seabird health and support adaptive management by quantifying abundance patterns and behaviors associated with habitats at sea, where seabirds spend the overwhelming majority of their lives. Adams’s team also employs conservation science to support resource managers on land, where seabirds are obligated to nest. His group provides scientific...
Seabird Ecology and Marine Planning
Seabirds are Department of the Interior (DOI) Trust Species and are protected under the Migratory Bird Treaty Act and the Endangered Species Act. To support science-based decision capacity and Marine Spatial Planning (MSP) among U.S. Government resource managers, Dr. Josh Adams and the WERC seabird team have partnered with the Bureau of Ocean Energy Management, U.S. Fish and Wildlife Service,...
Santa Cruz Field Station
Scientists at the Santa Cruz Field Station study sea otters and seabirds in their environment. The USGS Western Ecological Research Center has two research missions based in the Santa Cruz region:
Abundance and productivity of marbled murrelets (Brachyramphus marmoratus) off central California during the 2019 breeding season
Marbled murrelets (Brachyramphus marmoratus) have been listed as “endangered” by the State of California and “threatened” by the U.S. Fish and Wildlife Service since 1992 in California, Oregon, and Washington. Information regarding marbled murrelet abundance, distribution, population trends, and habitat associations is critical for risk assessment...

Habitat affinities and at-sea ranging behaviors among main Hawaiian Island seabirds: Breeding seabird telemetry, 2013–2016
Recent Hawaiʻi state clean energy policy mandates and federal interest in developing offshore renewable energy resources have prompted unsolicited lease requests for offshore wind energy infrastructure (OWEI) to be located in ocean waters off Hawaiʻi. This study describing at-sea ranging behaviors for five seabirds was intended to provide new...
Adams, Josh; Felis, Jonathan J.; Czapanskiy, Max Spatial and temporal diving behavior of non-breeding common murres during two summers of contrasting ocean conditions
Successful foraging of marine predators depends on environmental conditions, which also influence prey availability. Neutral or negative El Niño Southern Oscillation and Pacific Decadal Oscillation ocean conditions during the summer of 2013 and strongly positive conditions during the summer of 2015 in the northern California Current System...

Abundance and productivity of marbled murrelets (Brachyramphus marmoratus) off central California during the 2018 breeding season
Executive SummaryMarbled murrelets (Brachyramphus marmoratus) have been listed as “endangered” by the State of California and “threatened” by the U.S. Fish and Wildlife Service since 1992 in California, Oregon, and Washington. Information regarding marbled murrelet abundance, distribution, population trends, and habitat associations is critical...
Felis, Jonathan J.; Kelsey, Emily C.; Adams, Josh Diving behavior of Pink-footed Shearwaters Ardenna creatopus rearing chicks on Isla Mocha, Chile
Recent information reporting Pink-footed Shearwater Ardenna creatopus mortality from fisheries bycatch throughout its range has encouraged fisheries managers in Chile to evaluate and consider shearwater foraging behaviors to better evaluate risk. In response, we tracked six chickrearing adult Pink-footed Shearwaters from Isla Mocha, off south-...
Adams, Josh; Felis, Jonathan J.; Czapanskiy, Max; Carle, Ryan D.; Hodum, Peter J. Collision and displacement vulnerability to offshore wind energy infrastructure among marine birds of the Pacific Outer Continental Shelf
Marine birds are vulnerable to collision with and displacement by offshore wind energy infrastructure (OWEI). Here we present the first assessment of marine bird vulnerability to potential OWEI in the California Current System portion of the U.S. Pacific Outer Continental Shelf (POCS). Using population size, demography, life history,...
Kelsey, Emily C.; Felis, Jonathan J.; Czapanskiy, Max; Peresksta, David M.; Adams, Josh Carotenoid-based skin ornaments reflect foraging propensity in a seabird, Sula leucogaster
Carotenoid-based ornaments are common signalling features in animals. It has long been proposed that such ornaments communicate information about foraging abilities to potential mates. However, evidence linking foraging with ornamentation is largely missing from unmanipulated, free-ranging populations. To investigate this relationship, we studied...
Michael, Nathan P.; Torres, Roxana; Welch, Andreanna J.; Adams, Josh; Erandi Bonillas-Monge, Mario; Felis, Jonathan J.; Lopez-Marquez, Laura; Martínez-Flores, Alejandro; Wiley, Anne E. Selective occupancy of a persistent yet variable coastal river plume by two seabird species
Advances in telemetry and modeling of physical processes expand opportunities to assess relationships between marine predators and their dynamic habitat. The Columbia River plume (CRP) attracts sooty shearwaters Ardenna grisea and common murres Uria aalge, but how seabirds respond to variability in plume waters is unknown. We...

Felis, Jonathan J.; Adams, Josh; Kelsey, Emily C. Population-level plasticity in foraging behavior of western gulls (Larus occidentalis)
BackgroundPlasticity in foraging behavior among individuals, or across populations may reduce competition. As a generalist carnivore, western gulls (Larus occidentalis) consume a wide range of marine and terrestrial foods. However, the foraging patterns and habitat selection (ocean or land) of western gulls is not well understood, despite their...
Shaffer, Scott A.; Cockerham, Sue; Warzybok, Peter; Bradley, Russell W.; Jahncke, Jaime; Clatterbuck, Corey A.; Lucia, Magali; Jelincic, Jennifer A.; Cassell, Anne L.; Kelsey, Emily; Adams, Josh Plastic ingestion by Black-footed Albatross Phoebastria nigripes from Kure Atoll, Hawai'i: Linking chick diet remains and parental at-sea foraging distributions
We quantified the incidence (percentage of samples with plastic) and loads (mass, volume) of four plastic types (fragments, line, sheet, foam) ingested by Black-footed Albatross Phoebastria nigripes chicks raised on Kure Atoll, the westernmost Hawaiian colony. All 25 samples contained plastic, mostly in the form of foam and line. On average (± SD...
