I am a research biologist with the U.S. Geological Survey's Western Ecological Research Center. I am the lead biologist in charge of the Seabird Studies program located at WERC's Santa Cruz Field Station. My work focuses on understanding the distribution and abundance patterns of seabirds at sea, nesting biology, foraging ecology and conservation science. My current studies are focused in the California Current and Hawaii.

Identifying Kittlitz's Murrelet nesting habitat in North America at the landscape scale
The Kittlitz's Murrelet (Brachyramphus brevirostris) is a small, non-colonial seabird endemic to marine waters of Alaska and eastern Russia that may have experienced significant population decline in recent decades, in part because of low reproductive success and terrestrial threats. Although recent studies have shed new light on Kittlitz's Murrelet nesting habitat in a few discrete areas, the...Felis, Jonathan J.; Kissling, Michelle L.; Kaler, Robb S.A.; Kenney, Leah A.; Lawonn, Matthew J.
Ashy Storm-Petrel Oceanodroma homochroa mist-netting and capture rates in the California Channel Islands, 2004–2007
The California Channel Islands (CCI) provide essential nesting habitat for a significant portion of the world’s Ashy Storm-Petrel Oceanodroma homochroa (ASSP) breeding population, but true abundance at this locality is not well known. Land-based nocturnal mistnetting has been conducted sporadically in the CCI since 1976, with variation in techniques and methods. Using a standardized catch-perunit...Adams, Josh
Occurrence, morphometrics, and plumage variability among Leach’s Storm-Petrels Oceanodroma leucorhoa in the California Channel Islands, 1976–2015
We mist-netted and examined Leach’s Storm-Petrels Oceanodroma leucorhoa (LESP) caught during 1991–2015 at three locations in the California Channel Islands (CCI): Prince Island, Santa Barbara-Sutil islands and Scorpion Rock. Although mist-netting methods and effort varied between two study periods (1991–1995, 2004–2007 and 2015), during 750 h effort we captured 41 LESP during April–August, with...Adams, Josh; Carter, Harry R.; McChesney, Gerard; Whitworth, Darrell L.
Predictive mapping of seabirds, pinnipeds and cetaceans off the Pacific Coast of Washington
About this report This report supports Washington-led marine spatial planning and responsible stewardship of natural and cultural resources by the Olympic Coast National Marine Sanctuary. Washington state agencies and the sanctuary continually seek the best available science to improve management of marine uses and stewardship of resources (Etheridge et al., 2010; Washington Department of Fish...Menza, Charles; Leirness, Jeffery B.; White, Tim; Winship, Arliss; Kinlan, Brian P.; Kracker, Laura; Zamon, Jeannette E.; Ballance, Lisa; Becker, Elizabeth; Forney, Karin A.; Barlow, Jay; Adams, Josh; Pereksta, David; Pearson, Scott; Pierce, John; Jeffries, Steven J.; Calambokidis, John; Douglas, Annie; Hanson, Bradford C.; Benson, Scott R.; Antrim, Liam

Population divergence and gene flow in an endangered and highly mobile seabird
Seabirds are highly vagile and can disperse up to thousands of kilometers, making it difficult to identify the factors that promote isolation between populations. The endemic Hawaiian petrel (Pterodroma sandwichensis) is one such species. Today it is endangered, and known to breed only on the islands of Hawaii, Maui, Lanai and Kauai. Historical records indicate that a large population formerly...Welch, A. J.; Fleischer, R. C.; James, H. F.; Wiley, A. E.; Ostrom, P.
