Jonathan Felis
Biography
The research Jonathan Felis is involved in seeks to understand seabird foraging ecology and identify the processes responsible for habitat selection, particularly through the use of tracking technologies and at-sea surveys. As a geographer, Jonathan's goal is to apply these data spatially in order to better inform conservation and management decisions in the context of marine spatial planning.

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.
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.
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...

Pacific Continental Shelf Environmental Assessment (PaCSEA): Characterization of Seasonal Water Masses within the Northern California Current System Using Airborne Remote Sensing off Northern California, Oregon, and Washington, 2011–2012
Here, we use ocean color measurements (Figure 1) and sea surface temperature (SST) data collected using sensors mounted on low-flying aircraft to characterize NCCS water masses and identify patterns among seasons and between years. To accomplish this, we applied k-means clustering to measured and derived ecologically-relevant physical and bio-...
Schulien, J A; Adams, Josh; Felis, Jonathan J. 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...

Trends in mammalian predator control trapping events intended to protect ground-nesting, endangered birds at Haleakalā National Park, Hawaiʻi: 2000–14
Predation and habitat degradation by non-native species are principal terrestrial threats to the federally endangered Hawaiian Petrel (ʻuaʻu, Pterodroma sandwichensis) and Hawaiian Goose (nēnē, Branta sandvicensis) within Haleakalā National Park (HALE), Maui, Hawaiʻi. Since 1981, HALE has maintained a network of live traps to control invasive...

The pink-footed shearwater Ardenna creatopus has a breeding range restricted to 3 central-Chilean islands and travels north in the eastern Pacific Ocean during the non-breeding period. Despite its Vulnerable IUCN status, the locations and relative importance of core non-breeding areas and migratory pathways of the species are not well understood....
Felis, Jonathan J.; Adams, Josh; Hodum, Peter; Carle, Ryan D.; Colodro, Valentina Overlap of Pink-footed Shearwaters and central Chilean purse-seine fisheries: Implications for bycatch risk
Understanding susceptibility of seabirds to fisheries bycatch requires quantifying overlap of seabird at-sea habitat with fisheries’ distribution and effort. Pink-footed Shearwaters (Ardenna creatopus) are vulnerable seabirds that breed only in Chile. Recently, high rates of Pink-footed Shearwater bycatch (i.e. >1,500 observed mortalities 2015–...
Carle, Ryan D.; Felis, Jonathan J.; Vega, Rodrigo; Beck, Jessie; Adams, Josh; Lopez, Veronica; Hodum, Peter J.; González, Andrés; Colodro, Valentina; Varela, Tiare Does perspective matter? A case study comparing Eulerian and Lagrangian estimates of common murre (Uria aalge) distributions
Studies estimating species' distributions require information about animal locations in space and time. Location data can be collected using surveys within a predetermined frame of reference (i.e., Eulerian sampling) or from animal‐borne tracking devices (i.e., Lagrangian sampling). Integration of observations obtained from Eulerian and Lagrangian...

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...
