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
Sarah Guindre-Parker, Auteur ; H. Grant Gilchrist, Auteur ; Sarah Baldo, Auteur ; Oliver P. Love, AuteurWhile studies of achromatic plumage signaling are scarce relative to chromatic ornaments, achromatic ornaments have the potential to act as an efficient form of visual communication due to the highly conspicuous contrast between black and white [...]

Christine L. Madliger, Auteur ; Christina A. D. Semeniuk, Auteur ; Christopher M. Harris, Auteur ; Oliver P. Love, AuteurStress hormones (i.e., glucocorticoids such as corticosterone and cortisol) have been widely proposed as biomarkers of habitat quality and disturbance. However, there is growing evidence that baseline glucocorticoid (GC) levels are highly contex[...]

Sebastien Descamps, Auteur ; Mark R. Forbes, Auteur ; H. Grant Gilchrist, Auteur ; Oliver P. Love, Auteur ; Joel Bety, AuteurInfectious diseases can have dramatic impacts on animal population dynamics, but how they influence vital rates remains understudied. We took advantage of the appearance of an avian cholera epizootic in an arctic colony of common eiders Somateri[...]

Christie A. Macdonald, Auteur ; Emily A. McKinnon, Auteur ; H. Grant Gilchrist, Auteur ; Oliver P. Love, AuteurSex biases in distributions of migratory birds during the non-breeding season are widespread; however, the proximate mechanisms contributing to broad-scale sex-ratio variation are not well understood. We analyzed a long-term winter-banding datas[...]
Article
Eloise Rowland, Auteur ; Oliver P. Love, Auteur ; Jan J. Verspoor, Auteur ; Lani Sheldon, Auteur ; Tony D. Williams, AuteurTraditionally, studies of sexually size-dimorphic birds and mammals report that the larger sex is more sensitive to adverse environmental conditions during ontogeny. However, recent studies in avian species that exhibit moderate size-dimorphism [...]
Article
Sarah Guindre-Parker, Auteur ; Oliver P. Love, AuteurSupport against the condition-dependence of melanin plumage signals has relied on data from species exhibiting both melanin- and carotenoid-based plumage ornaments. As the mechanisms leading to variation in carotenoid- and melanin-based plumage [...]

Article
Pierre Legagneux, Auteur ; Holly L. Hennin, Auteur ; H. Grant Gilchrist, Auteur ; Tony D. Williams, Auteur ; Oliver P. Love, Auteur ; Joel Bety, AuteurTheoretically, individuals of migratory species should optimize reproductive investment based on a combination of timing of and body condition at arrival on the breeding grounds. A minimum threshold body mass is required to initiate reproduction[...]
