Article
Rolanda J. Steenweg, Auteur ; Pierre Legagneux, Auteur ; Glenn T. Crossin, Auteur ; H. Grant Gilchrist, Auteur ; T. Kurt Kyser, Auteur ; Oliver P. Love, AuteurMany birds change their partners every year and pairing may occur before arrival on the breeding grounds. Early pairing strategies can benefit mates by strengthening pair-bonds and increasing the rate of pre-breeding resource acquisition, leadin[...]
Article
Lykke Pedersen, Auteur ; Kevin C. Fraser, Auteur ; T. Kurt Kyser, Auteur ; Anders P. Tøttrup, AuteurUnderstanding how events throughout the annual cycle interact to influence individual fitness and hence population dynamics is crucial to optimize conservation strategies for migratory birds. Despite major advancements in technology, direct trac[...]

Kathryn M. Langin, Auteur ; Peter P. Marra, Auteur ; Zoltán Németh, Auteur ; Frank R. Moore, Auteur ; T. Kurt Kyser, Auteur ; Laurene M. Ratcliffe, AuteurEach spring, millions of songbirds migrate across the Gulf of Mexico on their way to breeding sites in North America. Data from radar and migration monitoring stations have revealed broad patterns in the spatial and temporal course of trans-Gulf[...]
Article
Marjorie C. Sorensen, Auteur ; J. Mark Hipfner, Auteur ; T. Kurt Kyser, Auteur ; D. Ryan Norris, AuteurUnderstanding the interactions between different periods of the annual cycle in migratory animals has been constrained by our inability to track individuals across seasons. In seabirds, virtually nothing is known about how diet quality during th[...]
Article
D. Ryan Norris, Auteur ; Peter Arcese, Auteur ; David Preikshot, Auteur ; Douglas F. Bertram, Auteur ; T. Kurt Kyser, Auteur1. For the overwhelming majority of species, we lack long-term information on the dynamics of populations. As a consequence, we face considerable uncertainty about how to discriminate among competing hypotheses of population decline and design c[...]

Samantha E. Franks, Auteur ; David B. Lank, Auteur ; D. Ryan Norris, Auteur ; Brett K. Sandercock, Auteur ; Caz M. Taylor, Auteur ; T. Kurt Kyser, AuteurAvian age-class discrimination is typically based on the completeness of the first prebasic molt. In several calidrid sandpiper species, juvenal flight feathers grown on Arctic breeding grounds are retained through the first three migrations. Th[...]
