How do energy stores and changes in these affect departure decisions by migratory birds? A critical view on stopover ecology studies and some future perspectives

H Schmaljohann, C Eikenaar - Journal of Comparative Physiology A, 2017 - Springer
In birds, accumulating energy is far slower than spending energy during flight. During
migration, birds spend, therefore, most of the time at stopover refueling energy used during …

Towards a conceptual framework for explaining variation in nocturnal departure time of songbird migrants

F Müller, PD Taylor, S Sjöberg, R Muheim, A Tsvey… - Movement Ecology, 2016 - Springer
Most songbird migrants travel between their breeding areas and wintering grounds by a

mechanisms remains surprisingly limited. It is important to identify the extent of individual …

Ecological factors influence timing of departures in nocturnally migrating songbirds at Falsterbo, Sweden

S Sjöberg, T Alerstam, S Åkesson, R Muheim - Animal Behaviour, 2017 - Elsevier
Most songbirds depart from stopover sites after sunset and migrate during the night. Several
