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

Abstract 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, migratory timings) and its association...
