Three decades of western sandpiper stopover dynamics during northward migration on the Pacific Coast of North America, 1992–2022

open access: yesJournal of Avian Biology, Volume 2026, Issue 2, March 2026.
Shorebirds typically spend more time fueling and refueling during migration than they spend in actual flight, and consequently their stopover ecology has important implications for fitness and conservation. We examined spatial variation and long‐term changes in stopover duration of radio‐tagged western sandpipers Calidris mauri over three decades on ...

Annual survival estimation of migratory songbirds confounded by incomplete breeding site-fidelity: study designs that may help [PDF]

open access: yesAnimal Biodiversity and Conservation, 2004
Many species of bird exhibit varying degrees of site–fidelity to the previous year’s territory or breeding area, a phenomenon we refer to as incomplete breeding site–fidelity. If the territory they occupy is located beyond the bounds of the study area or

Anthropogenic and Environmental Factors Influence Kentish Plover (Anarhynchus alexandrinus) Survival in a Conservation-Reliant Coastal Population

open access: yesBirds
Bird survival is influenced by both natural and anthropogenic factors, including weather conditions and oil spills. In this study, we examined the impact of a major oil spill (Prestige oil tanker) and climatic conditions (precipitation and wind) on ...

Contrasting abundance and residency patterns of two sympatric populations of transient killer whales (Orcinus orca) in the northern Gulf of Alaska [PDF]

open access: yes, 2012
Two sympatric populations of “transient” (mammal-eating) killer whales were photo-identified over 27 years (1984–2010) in Prince William Sound and Kenai Fjords, coastal waters of the northern Gulf of Alaska (GOA).
