Summary We examined how mate and site fidelity varied with age, experience sex, breeding experience, sex affected annual reproductive success lifetime output in a declining population of Cassin’s auklets ( Ptychoramphus aleuticus ). Our 276 study birds were 2–14 years recruited at age 2–12 years, had 0–11 years’ 0–8 the same nest box. Mate was significantly greater increasing males but not females. There also significant negative relationship between density (as measured by proportion box...
Abstract Understanding encounters between marine predators and fisheries across national borders outside jurisdictions offers new perspectives on unwanted interactions to inform ocean management predator conservation. Although seabird–fisheries overlap has been documented at many scales, remote identification of vessel lagged because movement data often are lacking. Here, we reveal albatrosses–fisheries associations throughout the North Pacific Ocean. We identified commercial fishing...

Abstract Characterizing demography of fisheries bycatch is essential to understanding impacts on populations long‐lived, low‐fecundity species. Northern Fulmars ( Fulmarus glacialis rogersii) represent >50% seabird in U.S. groundfish and halibut the North Pacific. Using specimens collected by federal observer programs, we document sex, age class, body condition 1,089 fulmars between 2004 2014. regional fulmar breeding phenology, assess seasonal variation relative composition a given sex...
Abstract Artificial habitat for cavity nesting birds can provide excellent opportunities research and conservation efforts but may expose species to the negative impacts of warming ambient temperatures with climate change. nest boxes have been successfully used monitor breeding activity Cassin's auklet ( Ptychoramphus aleuticus ), a small burrow‐nesting seabird, on Southeast Farallon Island (SEFI) since 1971. Mean monthly air SEFI during summer months increased at an annual rate roughly...
Responses to climate change by seabirds in the North Pacific may include range restrictions and require colonizing new habitats. To inform conservation actions supporting adaptations, we examined colonization of Año Nuevo Island, a nearshore island central California, Cassin's Auklets (Ptychoramphus aleuticus). We quantified population growth, reproduction, band returns, mortality, habitat metrics from 1995-2017 described management that facilitated colony persistence. Auklet breeding grew...
Summary Alien species are a driver of biodiversity loss, with impacts different aliens on native varying considerably. Identifying the contributions alien to declines could help target management efforts. Globally, seabirds breeding islands have proven be highly susceptible species. The colonies pink-footed shearwater ( Ardenna creatopus ) threatened by negative mammals. We combined monitoring data hierarchical model separate effects mammal assemblages burrow occupancy and hatching success...
Plastic debris is ubiquitous and increasing in the marine environment. A wide range of organisms ingest plastic its impacts are growing concern. Seabirds particularly susceptible to pollution, with high rates ingestion. Because plastics contain an array hazardous compounds, chemical ingestion concerning. Several researches on wild seabirds suggested accumulation plastic-derived chemicals seabird tissue. However, evidences were all indirect, it unclear whether can be source these pollutants....
Animals that regularly traverse habitat extremes between the subtropics and subarctic are expected to exhibit foraging behaviors respond changes in dynamic ocean habitats, these may facilitate adaptations novel changing climates. During chick-provisioning stage, Laysan albatross Phoebastria immutabilis parents undertake short- long-distance trips throughout vast central North Pacific Ocean. We examined GPS tracking data among albatrosses Hawai‘i characterize habitats during trips. The study...
