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.

Short-eared Owl tracking Appeal
Short-eared Owls are declining. By funding further research we will be able to work towards securing their future.
Tracking a research revolution
Newly-published work by BTO has reviewed the long-term patterns in the use of tracking devices on individual birds, and how the effects of the use of such devices are reported. This work highlights...
Track our Cuckoos as they migrate
The Cuckoo Tracking Project has been revealing new discoveries about how British Cuckoos migrate, and the challenges they face. Follow and support this ground-breaking project.
Dodging the blades: gulls and wind farms
Initial findings suggest that Lesser Black-backed Gulls in north-west England fly within wind farms, but may avoid wind turbines once there.
Assessing habitat use of Herring Gulls in the Morecambe Bay SPA using GPS tracking devices
Number of coastal Herring Gull populations have reduced markedly in recent years. The breeding gull colony of the South Walney and Piel Channel Flats Site of Special Scientific Interest (SSSI),...
Sample size required to characterize area use of tracked seabirds
Conflicts in resource use between humans and wildlife populations are increasingly determined through quantitative approaches. To better understand interactions between birds and human activities in...
Rachel acts as scientific liaison and research lead for Wales. Environmental law and the main drivers of ecological change differ between the Principality and England, and her job is to ensure that Welsh research priorities are reflected in BTO’s portfolio; that Welsh projects are developed and can be managed locally; and that Welsh policy and environmental audiences maintain a good understanding and appreciation of the BTO’s research activity.
Assessing behaviour of Lesser Black-backed Gulls from the Ribble and Alt Estuaries SPA using GPS tracking devices
Chris is a Senior Research Ecologist in International Research Team where he works on the ecology and conservation of Afro-Palaearctic migratory birds and of forest birds across the world. Projects primarily focus of population changes, habitats and migration strategies of these species.
