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 …

Early-life conditions have critical, long-lasting effects on the fate of individuals, yet early-life
activity has rarely been linked to subsequent survival of animals in the wild. Using high …

Wildlife conservation policies directed at common and widespread, but declining, species

secondary mating strategies: divorce and extra-pair mating, with the former potentially …

Many bird species produce two annual broods during a single breeding season. However,
not all individuals reproduce twice in the same year suggesting that double brooding is …

Migrating birds have to incorporate migration into their annual cycle, next to breeding and
