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.
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. You can read about the fortunes of 20 seabird species in...
Dodging the blades: gulls and wind farms
Offshore wind farms may affect birds in many ways, such as stopping them moving between places, or restricting access to areas where they feed. Collision risk is a key concern for seabirds, yet 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 Framework...
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. The breeding gull colony of the South Walney and Piel Channel Flats Site of Special Scientific Interest (SSSI),...
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 the non-...
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
Assessing the potential impact of additional mortality from anthropogenic causes on animal populations requires detailed demographic information. However, these data are frequently lacking, making...
The seabird wreck in the Bay of Biscay and South-Western Approaches in 2014: A review of reported mortality
Urban Breeding Gull Surveys: A Survey Design Simulation
Includes annex: Results for Northwest England. To support delivery of the latest census of the breeding seabird population of Britain and Ireland, a previous Natural England commissioned report (...
Assessing behaviour of Lesser Black-backed Gulls from the Ribble and Alt Estuaries SPA using GPS tracking devices
Curlews and godwits - the vanishing tribe
The study synthesised expert knowledge to determine the severity of various threats both in the breeding and non-breeding sites of the birds across all the major global flyways. Threats differed...
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. For...
Assessing the impact of offshore wind farms on seabird populations
New research led by Aonghais Cook of the BTO has tested a variety of analytical tools, or models, to assess the likely population-level consequences of the impacts arising from any individual wind...
Assessing offshore wind farm impact assessments for breeding seabirds
The construction of offshore wind farms is rapidly increasing as governments aim to reduce carbon emissions. However, since there is a growing body of evidence linking offshore wind farms to...
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.
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.
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
Addressing Uncertainty in Marine Resource Management; Combining Community Engagement and Tracking Technology to Characterize Human Behavior
Small-scale fisheries provide an essential source of food and employment for coastal communities, yet the availability of detailed information on the spatiotemporal distribution of fishing effort to...
GPS tracks and cutting edge stats shed new light on seabird flight heights
Offshore wind farms are now operating or under construction in many locations, but while spinning turbine blades are crucial for generating renewable energy, they also represent a potential threat...
