Can Cuckoos adapt their clocks to climate change?
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.
2023’s Cuckoos are tagged and ready to go
BTO has fitted 10 more Cuckoos with satellite tags, allowing scientists and the general public to follow these incredible birds on their annual migration.
Landscape fires disproportionally affect areas of conservation priority but only under low moisture conditions
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...
How important is it to standardise the measured mass of shorebirds weighed at varying intervals after capture?
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...
BTO goes batty
How our Acoustic Pipeline project is contributing to bat conservation in some of Europe’s most threatened landscapes.
Connectivity between countries established by landbirds and raptors migrating along the African-Eurasian flyway
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...
Pied Flycatcher population trends are driven by factors acting during migration and in non-breeding areas, an area which needs to be prioritised for future research.
Goose and Swan Monitoring Programme
This project tracks the abundance and breeding success of the UK’s native geese and migratory swans through winter surveys.
Tackling the challenge of avian influenza
Our Director of Science James Pearce-Higgins discusses highly pathogenic avian influenza and BTO's role in the response to the current outbreak.
Exciting research conducted by an international team shines a new light on Swift migration.
Meet the Class of 2022
BTO scientists tagged seven Cuckoos to in June 2022, to further our understanding of Cuckoo migration and survival.
PJ the Cuckoo: his legacy lives on
Record-breaking Cuckoo PJ has died in his summer territory in King's Forest, but data from his tag continues to inform our research.
What have the Cuckoos taught us?
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...
Eurasian African Bird Migration Atlas spreads its wings
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.
Achieving global targets for renewable energy
BTO's Aonghais Cook discusses the challenges associated with an environmentally sensitive, socially just transition to global renewable power.
Hotspots in the grid: avian sensitivity and vulnerability to collision risk from energy infrastructure interactions in Europe and north Africa
BTO travels to Europe!
BTO travels to key conferences in Europe to share research and experience with colleagues from around the globe.
Ringing data for conservation
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.
Rush or relax: migration tactics of a nocturnal insectivore in response to ecological barriers
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 International Team assisting in the analysis and development of a range of BTO datasets.
Warming temperatures drive at least half of the magnitude of long-term trait changes in European birds
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...
The future distribution of wetland birds breeding in Europe validated against observed changes in distribution
<p>Long-term effects of rewilding on species composition: 22 years of raptor monitoring in the Chernobyl Exclusion Zone</p>
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,...

Better utilisation and transparency of bird data collected by powerline companies
The continued increase in global energy demand requires expanding networks of power supply. High-voltage overhead powerlines, however, pose a collision and electrocution risk to some bird species if...
