BTO has a long history of working on migrants, from the first use of bird rings to look at the movements of birds. Our current work on long-distance migratory species covers two complementary approaches:
- the deployment of new tracking devices to understand the ecology, movements and non-breeding locations of individuals from breeding populations, many of which are declining
- analyses of long-term monitoring data, including from bespoke surveys, the Ringing and Nest Record Schemes, to identify drivers of population change
Migratory passerine birds in Britain carry Phytophthora ramorum inoculum on their feathers and "feet" at low frequency
Wind‐associated detours promote seasonal migratory connectivity in a flapping flying long‐distance avian migrant
Meet the Cuckoo class of 2019
There are still important questions to answer, so we have fitted four more Cuckoos with satellite tags this spring.
Our first Cuckoos are back
As part of our quest to improve our understanding of bird migration we have been satellite-tracking Cuckoos that breed here in the UK.

Crossing barriers: does flexibility provide resilience in a changing world?
Migratory barriers, such as the Sahara Desert, are thought to present a challenge to small migrant birds like Whinchat, but how much do we really know about the strategies these birds use when...
Bird Ringing Scheme
Bird ringing generates information on the survival, productivity and movements of birds, helping us to understand why populations are changing.
Differential migration of chiffchaffs (Phylloscopus collybita and Phylloscopus ibericus) in Europe and Africa
Avian migration strategies may include intra-specific variations, also known as differential migration.
Flight Lines: Tracking the wonders of bird migration
By pairing artists, storytellers and photojournalists with the researchers and volunteers studying our summer migrants, we are able to tell the stories of our migrant birds, and the work...
Curlews and godwits - the vanishing tribe
Collaborative research led by the BTO investigates reasons for recent losses in curlews and godwits worldwide and identifies conservation measures which could be put in place to halt the declines.
Unravelling the mysteries of Nightjar migration
New research involving the BTO has revealed important information about the migration routes and wintering grounds of the Nightjar for the first time. Their main wintering area is now known to be...
Samantha works on a range of projects examining the affect of climate and habitat change on bird populations, with a particular focus on migrants and waders.
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.
Cuckoo declines linked to different migration routes to Africa
When the BTO began ground-breaking Cuckoo tracking research in 2011, we had very little idea where these birds spent the winter or how they got there. Our latest research not only reveals...
