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.
Prior to 2011, we knew very little about what the UK's breeding Cuckoos did once they left the UK for the winter months. Over a decade since the BTO Cuckoo Tracking Project was born, we reflect on...
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.
New research involving BTO has confirmed the theory the migratory birds use different strategies at different points on their migratory journeys, speeding up when passing through inhospitable regions...
Máire is a Research Ecologist in the Framing Futures team and specialises in the analysis of BTO data, especially where these include the integration of field data and geospatial and remote sensing datasets, and the publication of research results.
Climate change is impacting wild populations, but its relative importance compared to other causes of change is still unclear. Many studies assume that changes in traits primarily reflect effects of...
Over 2,000 km² of Belarus previously given over to intensive agriculture and dense settlements was affected by the 1986 reactor meltdown at the Chernobyl Nuclear Plant in Ukraine. Since then,...
