Article
Adam K. Janke, Auteur ; Michael J. Anteau, Auteur ; Nicholas Markl, Auteur ; Joshua D. Stafford, AuteurBreeding birds use a range of nutrient accumulation and allocation strategies to meet the nutritional demands of clutch formation and incubation. On one end of the spectrum, capital breeders use stored nutrients acquired prior to clutch formatio[...]
Article
Benjamin J. O'Neal, Auteur ; Joshua D. Stafford, Auteur ; Ronald P. Larkin, AuteurA recently developed radar-based technique permitted empirical re-evaluation of the established but poorly supported theory that migrating North American waterfowl (Anatidae) use landscape features such as rivers as leading lines. Ducks departin[...]

John A. Dassow, Auteur ; Michael W. Eichholz, Auteur ; Joshua D. Stafford, Auteur ; Patrick J. Weatherhead, AuteurParent birds should take greater risks defending nests that have a higher probability of success. Given high rates of mammalian nest predation, therefore, parents should risk more for nests in areas with a lower risk of mammalian predation. We t[...]

Heath M. Hagy, Auteur ; Joshua D. Stafford, Auteur ; Randolph V. Smith, Auteur ; Aaron P. Yetter, Auteur ; Christopher S. Hine, Auteur ; Michelle M. Horath, Auteur ; Christopher J. Whelan, AuteurThe interaction of animals with their food can yield insights into habitat characteristics, such as perceived predation risk and relative quality. We deployed experimental foraging patches in wetlands used by migrating dabbling ducks Anas spp. i[...]

Benjamin J. O'Neal, Auteur ; Joshua D. Stafford, Auteur ; Ronald P. Larkin, AuteurLocal and migratory movements aloft have important implications for the ecology and conservation of birds, but are difficult to quantify. Weather surveillance radar (WSR) offers a unique tool for observing movements of birds, but until now has b[...]
