BTO science is fundamental to conservation action in the UK, and contributes significantly to Europe-wide assessments. BTO's long-term monitoring schemes provide the data to inform conservation priorities, but also BTO research contributes significantly to conservation science. This has been both at the level of individual species, identifying causes of decline and testing solutions, and providing the evidence to inform more cross-cutting policy needs.
Winter Gull Survey relaunched after 20 years to assess vulnerable gull populations
Help us collect vital data about these threatened birds.
Linking climate warming and land conversion to species’ range changes across Great Britain
The most notable changes over the past 75 years have been an increase in temperature and a loss of roughly 90% of lowland meadow and pasture, mainly converted to arable farmland and improved...
The current state of nature
The UK, like most other countries worldwide, has experienced a significant loss of biodiversity. The trends in nature presented in this report cover, at most, 50 years, but these follow on from major...
The status of the UK breeding European Turtle Dove Streptopelia turtur population in 2021
The UK Turtle Dove population is thought to have peaked around 1970, when there were an estimated 125,000 pairs. At this time, the species’ range extended into south-west England, eastern Wales,...
A crowded ocean: the need for demographic and movement data in seabird conservation
To implement effective conservation actions, locally and globally, we need to quantify the importance of the multiple, often interacting, threats to seabird population growth rates. Population models...
Detecting Brown Rats on seabird islands
Introduced Brown Rats can devastate seabird colonies, predating both eggs and chicks. Can we use bioacoustic technology to detect and monitor this threat?
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.
Do Marsh Tits modify their behaviour to reduce competition?
Competition between species has been put forward as a possible reason for the declines seen in some bird species, including Marsh Tit and Willow Tit, but confirming a causal link between competition...
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...
Monitoring five decades of change in the UK’s rarest breeding birds through citizen science: the Rare Breeding Birds Panel
Wave of avian influenza hitting Black-headed Gulls
Fears grow around the new wave of Avian Flu as the disease kills thousands of inland gulls.
What role do protected areas play in bird conservation?
The UK has many different kinds of protected area, but how effective are they for bird conservation?
A review of the impacts of air pollution on terrestrial birds
A review paper by BTO considers 203 studies of the effects of air pollution on 231 bird species. Of these studies, 82% document at least one negative effect associated with increasing levels of...
Can migrant birds wait until we have all the answers?
Research led by our CEO, Juliet Vickery, makes the case to act now to stem migrant bird population declines instead of waiting for more evidence.
Curlew collaboration to boost breeding success
Research from BTO and the University of East Anglia reveals how land management can support the breeding success of this declining species.
Conservation status of birds in Wales gets updated
Find out what the latest 'Birds of Conservation Concern' review means for species in Wales.
Framework for assessing and mitigating the impacts of offshore wind energy development on marine birds
The incursion of Highly Pathogenic Avian Influenza (HPAI) into North Atlantic seabird populations: an interim report from the 15th International Seabird Group conference
The numbers of threatened birds are greater on UK sites with the highest levels of protection.
While there is plenty of evidence to demonstrate that protected areas are effective at protecting natural habitats, their benefits for birds and other species have been less well-studied. This study...
BTO goes batty
How our Acoustic Pipeline project is contributing to bat conservation in some of Europe’s most threatened landscapes.
The Making of Into the Red
When 140 artists and writers come together, united by a common goal: to raise funds for the UK's most vulnerable birds.
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...
