This study builds on previous work as part of the ‘Polesia: wilderness without borders’ project, which developed methods to map and analyse fires using satellite imagery and other remote-sensing...
Arctic Skuas breed in dwindling numbers on Scotland’s northern coasts and islands. The Arctic Skua is the fastest declining seabird species in the UK and has been on the Birds of Conservation...
Collaborative research involving BTO has examined the effects of the conflict in Ukraine on the migration of the endangered Greater Spotted Eagle.
Last week’s blog predicted the possible early arrival of Bee-eaters in the UK. Sadly, the only individual recorded was a bird found dead in a Dorset garden. Continuing the theme, Bee-eaters are...
Research in collaboration with BTO scientists has used data from satellite-tracked adult male Cuckoos to show that although all birds returned to the same breeding grounds in consecutive years, the...
The study, led by the Institut de Ciències del Mar and Estación Biológica de Doñana, CSIC, Spain, used diet samples collected in January 2022 at the Fuente de Piedra – an inland lake in Spain...
Where do Arctic Skuas go when they are not in Scotland? Helen and David Aiton take us through their fieldwork seasons for BTO’s Arctic Skua tracking project, which has followed these fascinating...
The results showed that although the actual amount of change had been greatest on the breeding grounds, cumulative exposure to changes in direct mortality risk and climate were...
Cuckoos aren’t returning to the UK earlier, even as spring advances – but why? BTO research reveals new insights into the timing of this species’ migratory cycle.
BTO has fitted 10 more Cuckoos with satellite tags, allowing scientists and the general public to follow these incredible birds on their annual migration.
This study identified five fires reaching more than 100 km2, a threshold often used to classify ‘megafires’. Frequent spring and summer fires predominantly started in agricultural areas, where...
This paper examines this phenomenon using captures of Knot, Turnstone, Dunlin and Semipalmated Sandpiper in Delaware Bay, USA. As these waders were caught whilst actively feeding on the eggs of...
How our Acoustic Pipeline project is contributing to bat conservation in some of Europe’s most threatened landscapes.
Each year, more than two billion birds migrate along the African-Eurasian flyway. The increasing availability of tracking technology, involving attaching very small devices to migrant songbirds, has...
This project tracks the abundance and breeding success of the UK’s native geese and migratory swans through winter surveys.
Our Director of Science James Pearce-Higgins discusses highly pathogenic avian influenza and BTO's role in the response to the current outbreak.
BTO scientists tagged seven Cuckoos to in June 2022, to further our understanding of Cuckoo migration and survival.
Record-breaking Cuckoo PJ has died in his summer territory in King's Forest, but data from his tag continues to inform our research.
Over a decade since the Cuckoo Tracking Project began, we’ve learnt an incredible amount.
The Eurasian African Bird Migration Atlas makes the results of ringing and tracking data available to anyone wanting to explore the migration and movements of European birds.
BTO's Aonghais Cook discusses the challenges associated with an environmentally sensitive, socially just transition to global renewable power.
BTO travels to key conferences in Europe to share research and experience with colleagues from around the globe.
Amidst widespread declines, how can we ensure conservation is targeted and effective? Analysis of ringing data to detect patterns of survival and productivity may be key to answering this question.
