The UK supports internationally important populations of breeding seabirds. BTO is a partner in Britain and Ireland's Seabird Monitoring Programme and supports the current national census – Seabirds Count. Information from BTO's Retrapping Adults for Survival scheme and Nest Record Scheme also contributes to our understanding of seabird demography. Through analyses of data and field-based tracking projects, our research considers the many drivers of seabird population change, including climate change and renewable energy schemes.
Public preferences for multiple dimensions of bird biodiversity at the coast: insights for the cultural ecosystem services framework
Operation Wader Appeal
Urgent action is needed to tackle the decline of breeding wader populations in the UK.
UK wetlands get a health check
The Wetland Bird Survey Alerts, published today, assesses change for 471 site-species populations on 82 SPA’s. Found out how our protected wetland sites are faring.
Avian vulnerability to wind farm collision through the year: insights from Lesser Black-backed Gulls (Larus fuscus) tracked from multiple breeding colonies
New BTO research has explored how vulnerable Lesser Black-backed Gulls breeding in Britain are to collisions with wind turbines whilst on migration and during the winter months, as well as during...
Stories of rampaging 'seagulls' dominate column inches in the holiday season. Our BTO gull experts take a look at the facts behind the headlines.
Quantifying avian avoidance of offshore wind turbines: Current evidence and key knowledge gaps
Northern Ireland Seabird Report 2018
Puffin numbers remain stable, Herring and Lesser Black-backed Gull both increase and Mediterranean Gull breeds in its highest numbers in 2018.
Dodging the blades: gulls and wind farms
Initial findings suggest that Lesser Black-backed Gulls in north-west England fly within wind farms, but may avoid wind turbines once there.
Improving understanding of the possible relationship between improving freshwater and coastal water quality and bird interest on designated sites - phase 1 review
Over the past 50 years there has been widespread improvement in water quality in many freshwater and coastal systems driven by domestic and European legislation, most recently the EU Water...
Assessing habitat use of Herring Gulls in the Morecambe Bay SPA using GPS tracking devices
Number of coastal Herring Gull populations have reduced markedly in recent years.
Results of the third Non-Estuarine Waterbird Survey, including Population Estimates for Key Waterbird Species
During December, January and February of the winter of 2015/16 the BTO organised the third Non-estuarine Waterbird Survey (NEWS III), the fourth in a series of coordinated winter surveys of...

Katharine works as a Research Ecologist analysing quantitative data from a range of projects from Wales and the rest of the UK with a focus on wetland and marine species.
Implicit assumptions underlying simple harvest models of marine bird populations can mislead environmental management decisions
Potential Biological Removal (PBR) is a simple harvest model. PBR is used for assessing impacts of offshore wind farms on seabird populations. Implicit assumptions about density dependence within...
Sample size required to characterize area use of tracked seabirds
Conflicts in resource use between humans and wildlife populations are increasingly determined through quantitative approaches. To better understand interactions between birds and human activities...
The seabird wreck in the Bay of Biscay and South-Western Approaches in 2014: A review of reported mortality
Between December 2013 and February 2014, a series of storm events occurred in areas of the North Atlantic frequented by migratory seabirds. Prolonged exposure to sustained storm conditions...
Urban Breeding Gull Surveys: A Survey Design Simulation
Includes annex: Results for Northwest England.
Assessing behaviour of Lesser Black-backed Gulls from the Ribble and Alt Estuaries SPA using GPS tracking devices
Curlews and godwits - the vanishing tribe
Collaborative research led by the BTO investigates reasons for recent losses in curlews and godwits worldwide and identifies conservation measures which could be put in place to halt the declines.
Providing Data for Rapid Condition Assessment of Non-Breeding Waterbird SPAs in England: Phase II
This report explores means by which a standardised trend analysis of data from the Wetland Bird Survey (WeBS) can aid rapid assessment of condition for non-breeding waterbird SPAs in England.
Assessing the impact of offshore wind farms on seabird populations
New research from the BTO has examined the different analytical tools used to assess the likely population-level impact of offshore wind farm developments on seabirds, finding that these vary...
Assessing offshore wind farm impact assessments for breeding seabirds
As the number of offshore wind farms increases, it is important to correctly assess the impact that these developments can have on wildlife. New research led by the BTO examines this situation for...
Liz's current job is to develop research projects principally concerned with wetland and marine issues. Her most recent work has focused on understanding the impacts of the renewable industry on seabirds. Previously to joining the BTO, Liz's main research interests involved quantifying the factors that determine the foraging performance and energetics of seabirds.
