The UK’s inland and coastal wetlands support internationally important populations of non-breeding waterbirds, originating from breeding grounds in this country to the high Arctic. Through the Wetland Bird Survey (WeBS) and Non-Estuarine Waterbird Survey (NEWS), we monitor these populations, providing data that inform site protection, international obligations and research on the drivers of population change. This has encompassed studies of climate change and renewable energy schemes, habitat change, disturbance and the effect of introduced non-native species.

Waders wane while geese gain
The work gives revised population estimates for 98 different species that winter in Great Britain, using data collected by many thousand birdwatchers to calculate either the average peak winter...
Habitat- and species-mediated short- and long-term distributional changes in waterbird abundance linked to variation in European winter weather.
A tale of two plovers
The new study estimated that the number of Little Ringed Plover breeding in the UK had risen by 71% between 1984 and 2007, to 1,239 pairs. The species’ core range remained in England, although...
Make your wetland birding count with WeBS
WeBS surveyors monitor the UK's internationally important non-breeding waterbirds. Following a tradition begun in 1947, wetland sites are counted once per month, providing data for population and...
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),...
Keep an eye on Herons and egrets with the Heronries Census
Contribute to the annual survey of all Grey Herons, Little Egrets, Cormorants and scarcer herons nesting in the UK.
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-...
Waders in decline in Strathallan, Scotland
Long-term studies can make an important contribution to our understanding of wader decline, as is demonstrated by work carried out by BTO’s Regional representative for Perthshire, Mike Bell. Mike had...
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.
Rachel acts as scientific liaison and research lead for Wales. Environmental law and the main drivers of ecological change differ between the Principality and England, and her job is to ensure that Welsh research priorities are reflected in BTO’s portfolio; that Welsh projects are developed and can be managed locally; and that Welsh policy and environmental audiences maintain a good understanding and appreciation of the BTO’s research activity.
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...
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.
Graham works on the design and analysis of results of national surveys of wild birds. He is responsible for the development of Wetland Bird Survey Database, Wetland Bird Survey Alerts system and Waterbird Indicators. He also researches into factors driving population trends in waterbirds.
Graham is also responsible for the development of BTO's GIS capabilities (including staff training).
Teresa is responsible for managing the Wetland Bird Survey (WeBS). WeBS is a partnership between the British Trust for Ornithology, the Royal Society for the Protection of Birds and the Joint Nature Conservation Committee in association with the Wildfowl and Wetlands Trust.
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
Niall manages a team of seven staff undertaking pure and applied research on the UK’s waterbirds and 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.
Survival estimates of Northern gannets Morus bassanus in Alderney: Big data but low confidence
Use of environmental stratification to derive non-breeding population estimates of dispersed waterbirds in Great Britain
Going with the flow? Costs and benefits of river flow variability to riverine birds
Data from 17 river birds were analysed to show that species associated with upland environments (e.g. Grey Wagtail) had a higher probability of occurrence with high flows, while those that forage...
