- Recent technological development has made it possible to pinpoint precise locations of small migratory songbirds throughout their annual cycle, providing the opportunity for improving our understanding of year-round habitat use. Here, we use GPS loggers to map the exact location and habitat use at stationary sites throughout the annual cycle of a long-distance migratory songbird, the Red-backed Shrike Lanius collurio. Although the main staging sites confirmed previous findings from light-level geolocation studies, one individual wintered in south-western Chad, an area with only a few historical records of this species. This study highlights opportunities for answering new questions and gaining more knowledge using fine-scale tracking of migratory songbirds.
