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.

Lasso Penalisation identifies consistent trends over time in landscape and climate factors influencing the wintering distribution of the Eurasian Curlew (Numenius arquata)
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...
Landscape fires disproportionally affect areas of conservation priority but only under low moisture conditions
This study identified five fires reaching more than 100 km2, a threshold often used to classify ‘megafires’. Frequent spring and summer fires predominantly started in agricultural areas, where...
Waterbirds in the UK 2021/22: The Wetland Bird Survey and Goose & Swan Monitoring Programme
How important is it to standardise the measured mass of shorebirds weighed at varying intervals after capture?
This paper examines this phenomenon using captures of Knot, Turnstone, Dunlin and Semipalmated Sandpiper in Delaware Bay, USA. As these waders were caught whilst actively feeding on the eggs of...

News from the Northern Ireland Birdwatcher's Conference
The BTO Northern Ireland Birdwatchers' Conference showcases bird research, monitoring, and conservation work undertaken in Northern Ireland and further afield.
Curlew are highly faithful to a small winter range, a finding which will inform conservation management for this Red-listed species.
In a collaborative study led by the University of Hull, BTO scientists aimed to find out more by establishing the overwinter home range size (the size of the space used by the birds during winter) of...
Goose and Swan Monitoring Programme
This project tracks the abundance and breeding success of the UK’s native geese and migratory swans through winter surveys.
Dragons and damsels
You can submit your dragonfly and damselfly sightings to BTO via BirdTrack or Garden BirdWatch. Find out why these records are so important in Rob Jaques' blog.
