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.
Youth Summit 2024 – much more than we hoped for
Read how dedicated volunteers, speakers and partners all came together to make this an incredible second Summit.
Spatially targeted nature-based solutions can mitigate climate change and nature loss but require a systems approach
Reducing greenhouse gas (GHG) emissions is one of the greatest challenges humankind is currently facing. A growing coalition of countries are now pledging to achieve net zero emissions, which means...
Anthropogenic climate and land-use change drive short-and long-term biodiversity shifts across taxa
This collaborative research involving BTO attempted to start understanding how habitat change and climate change interact. The study examined changes in over 1,000 bird, butterfly, moth and plant...
Astounding Short-eared Owl movements revealed
International research led by BTO has revealed that Short-eared Owls make astonishing nomadic migrations between nest sites as far apart as Scotland and Arctic Russia.
Future impact of climate change on threatened seabirds
New BTO research predicts seabird declines of up to 90% by 2050 in Britain and Ireland under a ‘business as usual’ climate scenario.
Adjacent habitats vital for intertidal waders
A new study has revealed contrasting habitat use between and within Bar-tailed Godwits and Curlews wintering on the Wash.
Winter Gull Survey relaunched after 20 years to assess vulnerable gull populations
Help us collect vital data about these threatened birds by volunteering for the Winter Gull Survey.
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.
