    Low fitness at low latitudes: Wintering in the tropics increases migratory delays and mortality rates in an Arctic breeding shorebird 
    Reneerkens, Jeroen; Versluijs, Tom S. L.; Piersma, Theunis; Alves, Jose; Boorman, Mark; Corse, Colin; Gilg, Olivier; Hallgrimsson, Gunnar Thor; Lang, Johannes; Loos, Bob; Ntiamoa‐Baidu, Yaa; Nuoh, Alfred A.; Potts, Peter M.; Horn, Job; Lok, Tamar (Wiley, 2019-10-04)
    Evolutionary theories of seasonal migration generally assume that the costs of longer migrations are balanced by benefits at the non-breeding destinations. We tested, and rejected, the null hypothesis of equal survival and timing of spring migration ...

    Why do earlier‐arriving migratory birds have better breeding success? 
    Morrison, Catriona; Alves, Jose; Gunnarsson, Tomas Gretar; Þórisson, Böðvar; Gill, Jennifer A. (Wiley, 2019-07-19)
    In migratory birds, early arrival on breeding sites is typically associated with greater breeding success, but the mechanisms driving these benefits are rarely known. One mechanism through which greater breeding success among early arrivers can potentially ...
