    A Migratory Divide Among Red-Necked Phalaropes in the Western Palearctic Reveals Contrasting Migration and Wintering Movement Strategies 
    van Bemmelen, Rob S. A.; Kolbeinsson, Yann; Ramos, Raül; Gilg, Olivier; Alves, Jose; Smith, Malcolm; Schekkerman, Hans; Lehikoinen, Aleksi; Petersen, Ib Krag; Þórisson, Böðvar; Sokolov, Aleksandr A.; Välimäki, Kaisa; van der Meer, Tim; Okill, J.

G.; Tulp, Ingrid (Frontiers Media SA, 2019-04-04)
    Non-breeding movement strategies of migratory birds may be expected to be flexibly adjusted to the distribution and quality of habitat, but few studies compare movement strategies among populations using distinct migration routes and wintering areas. ...

    Vegetation structure influences predation rates of early nests in subarctic breeding waders 
    Laidlaw, Rebecca; Gunnarsson, Tomas Gretar; Méndez Aragón, Verónica; Carneiro, Camilo; Þórisson, Böðvar; Wentworth, Adam; Gill, Jennifer A.; Alves, Jose (Wiley, 2020-03-13)
    Ground-nesting species are vulnerable to a wide range of predators and often experience very high levels of nest predation. Strategies to reduce nest vulnerability can include concealing nests in vegetation and/or nesting in locations in which nests ...

    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 ...
