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.
Winter Gull Survey relaunched after 20 years to assess vulnerable gull populations
Help us collect vital data about these threatened birds.
Flight heights obtained from GPS versus altimeters influence estimates of collision risk with offshore wind turbines in Lesser Black-backed Gulls Larus fuscus
As previous BTO research has shown, bird-borne tracking devices are essential for shedding light on seabird flight behaviour. Different methods for gathering flight height information within tracking...
How do offshore wind farms affect seabird behaviour?
Research reveals a crucial link between wind farm design and Sandwich Tern behaviour in the North Sea.
Arctic Skua migration: stories from the field
Where do Arctic Skuas go when they are not in Scotland? Helen and David Aiton take us through their fieldwork seasons for BTO’s Arctic Skua tracking project, which has followed these fascinating...
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...
Emma is responsible for managing the BTO Winter Gull Survey (WinGS) through the coordination of the BTOs Regional Network of volunteers.
Help monitor the UK’s threatened gull species by taking part in the Winter Gull Survey.
The Winter Gull Survey collects information about our wintering gull populations, through the coordinated effort of volunteer surveyors across the UK. It will run over the winters of 2023/24 and...
Avian influenza spreads into more threatened seabird species
Thousands of seabirds suspected to have died from avian influenza are once again washing up on UK beaches.
Analysis of waterbird population trends for Northern Ireland’s sea loughs: assessing the potential impacts of aquaculture and disturbance. Part 3 – Larne Lough, Killough Harbour and Dundrum Inner Bay
Assessing movements of Lesser Black-backed Gulls using GPS tracking devices in relation to the Galloper Wind Farm<br />
Reduced breeding success in Great Black-backed Gulls Larus marinus due to harness-mounted GPS device
Studies involving fitting animals with bio-logging devices have provided essential information on behaviour, ecology, physiology and ultimately species conservation. Much BTO research in recent years...
Avian influenza mortality rises in threatened gull and tern colonies
Black-headed Gulls continue to suffer as the disease spreads to Common Terns.
Waterbirds in the UK 2021/22: The Wetland Bird Survey and Goose & Swan Monitoring Programme
Northern Ireland Seabird Report 2022
The 10th NI Seabird Report charts the fortunes of Northern Ireland's breeding seabird species and sheds light on the initial impact of avian flu.
Avian flu: what next?
The HPAI workshop report includes discussions about the impacts of the disease, planning for future outbreaks, and conservation and research priorities.
Daily, seasonal and annual variation in area use of Lesser Black-backed Gulls (Larus fuscus) related to offshore renewable developments
A review to inform the assessment of the risk of collision and displacement in petrels and shearwaters from offshore wind developments in Scotland
Framework for assessing and mitigating the impacts of offshore wind energy development on marine birds
Thoracic harnesses are not suitable for Kittiwake tagging studies.
Biologging devices including GPS and satellite tags, which attach to individual animals and collect information on their movements, are increasingly deployed in ecology and conservation research....
The incursion of Highly Pathogenic Avian Influenza (HPAI) into North Atlantic seabird populations: an interim report from the 15th International Seabird Group conference
Analysis of waterbird population trends for Northern Ireland’s sea loughs: assessing the potential impacts of aquaculture and disturbance: Part 2 – Belfast Lough and Lough Foyle
Analysis of waterbird population trends for Northern Ireland’s sea loughs: assessing the potential impacts of aquaculture and disturbance. Part 1 – Strangford Lough and Carlingford Lough
Sharing our seabird research
From Black Guillemots to Eider and Arctic Skua, our scientists discussed a range of research at the International Seabird Group Conference in August.
Urban and coastal breeding lesser black-backed gulls (Larus fuscus) segregate by foraging habitat
Tackling the challenge of avian influenza
Our Director of Science James Pearce-Higgins discusses highly pathogenic avian influenza and BTO's role in the response to the current outbreak.
