Delineating large‐scale migratory connectivity of reed warblers using integrated multistate models

Assessing the extent of large‐scale migratory connectivity is crucial for understanding the evolution of migratory systems and effective species conservation. It has been, however, difficult to elucidate the annual whereabouts of migratory populations of small animals across the annual cycle. Here, we use the reed warbler (Acrocephalus scirpaceus) as one of the most frequently ringed passerines in Europe to demonstrate how ring re‐encounter and geolocator data can be used to effectively quantify range‐wide distribution of different populations.
