Linking migratory performance to breeding phenology and productivity in an Afro-Palearctic long-distance migrant

open access: yesScientific Reports, 2021
Understanding the relationship between migratory performance and fitness is crucial for predicting population dynamics of migratory species. In this study, we used geolocators to explore migration performance (speed and duration of migratory movements ...

The relative importance and biological significance of non-stop and intermittent flight strategies in bird migrants crossing the Sahara [PDF]

open access: yes, 2007
IX Summary The aim of this thesis was to investigate the flight and resting strategies of birds crossing the Sahara on migration. In order to overcome the severe limitations of ground observations, we chose radar to obtain continuous data of the temporal

open access: yes, 2006
The urge of captive birds to migrate manifests itself in seasonally occurring restlessness, termed "Zugunruhe." Key insights into migration and an endogenous basis of behavior are based on Zugunruhe of migrants but have scarcely been tested in ...

Paternal transmission of migration knowledge in a long-distance bird migrant

open access: yesNature Communications, 2022
While advances in biologging have revealed many spectacular animal migrations, it remains poorly understood how young animals learn to migrate. Even in social species, it is unclear how migratory skills are transmitted from one generation to another and ...

Spatial structure in migration routes maintained despite regional convergence among eastern populations of Swainson’s Thrushes

open access: yesMovement Ecology, 2021
Background Migratory connectivity links the different populations across the full cycle and across the species range and may lead to differences in survival among populations.

Forecasting nocturnal bird migration for dynamic aeroconservation: The value of short‐term datasets

open access: yesJournal of Applied Ecology
Placing wind turbines within large migration flyways, such as the North Sea basin, can contribute to the decline of vulnerable migratory bird populations by increasing mortality through collisions. Curtailment of wind turbines limited to short periods
