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.
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

Ros works as a Research Ecologist supporting the fieldwork, analysis and reporting work on the Wetland & Marine Research Team.
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 PBR were tested. We demonstrated that PBR gives misleading results when assumptions are not met. We...
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 in the marine environment, telemetry is routinely used to characterize the area use of species, but...
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 was followed by an unprecedented level of seabird mortality, apparently due to starvation, exhaustion and...
Assessing behaviour of Lesser Black-backed Gulls from the Ribble and Alt Estuaries SPA using GPS tracking devices
Curlews and godwits - the vanishing tribe
New 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
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 widely and are influenced to a large extent by the assumptions made at the start of the analysis.
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 seabirds, considering the current environmental impact assessment process in light of the key factors...
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.
Ian supports the Ecologists within BTO who are undertaking research into bird populations and ecology.
Aonghais undertakes research examining the causes of changes in the abundance of waterbirds and seabirds, and potential impacts of man-made developments on their populations
Chris's principal role is undertaking research into changes in the abundance and foraging behaviour of seabirds and waterbirds in relation to both man-made impacts and environmental processes. He takes a central role in conducting and developing marine research projects at BTO.
Niall manages a team of seven staff undertaking pure and applied research on the UK’s waterbirds and seabirds.
Addressing Uncertainty in Marine Resource Management; Combining Community Engagement and Tracking Technology to Characterize Human Behavior
GPS tracks and cutting edge stats shed new light on seabird flight heights
New research led by the BTO has used a combination of GPS-tracking and advanced statistics to provide new insights into seabird flight heights by night and day. This study gives important information on the risk of seabirds colliding with offshore wind turbines and at a time when governments...
