New tracking devices our transforming our understanding of bird movements, and the fate of individuals. As part of MoveTech Telemetry, BTO plays an important role in the development of these devices, as well as using them for innovative research. Different tracking devices, such as geolocators to satellite tags, are documenting for the first time the global migrations of a range of species, from Willow Warblers and Spotted Flycatchers to Arctic Skuas and Cuckoos. At a more local scale, these technologies also enable us to study habitat use and home ranges, whether of raptors in East Anglia, or waders on the coast.

Individual variability and versatility in an eco-evolutionary model of avian migration
It has been known for some time that Blackcaps employ several different migration strategies. Birds breeding in central Europe either migrate south-west or south-east for winter, with a switch...
