Capturing data in the field with citizen science and species expertise
Browse the range of active BTO projects requiring support. Learn what they contribute to science, and how to participate.
Bird Ringing Scheme
Bird ringing generates information on the survival, productivity and movements of birds, helping us to understand why populations are changing.
Contributions & findings
- Winter wren populations show adaptation to local climate
- Flexibility in the timing of post-breeding moult in British passerines
- Latitudinal gradients in the productivity of European migrant warblers have not shifted northwards during a period of climate change
- Integrating demographic data: towards a framework for monitoring wildlife populations at large spatial scales
BirdTrack
BirdTrack is a free and convenient way of storing your bird records online. BirdTrack lets you keep up to date with what others are seeing, view the latest trends, and contribute your data to BTO science.
Breeding Bird Survey
BBS monitors the population changes of 117 breeding bird species across the UK thanks to the dedication of almost 3,000 volunteers who survey their randomly selected 1-km square each spring.
Cuckoo Tracking Project
Help us follow Cuckoos on migration and discover why they are in decline.
Contributions & findings
Garden BirdWatch
Help track the changing fortunes of our garden birds alongside 12,000 other Garden BirdWatchers
Heronries Census
Annual survey of all Grey Herons, Little Egrets, Cormorants and scarcer herons nesting in the UK
Contributions & findings
- The latest Grey Heron population trends from the Heronries Census are discussed on the Grey Heron page in the BTO's BirdTrends report.
- The modelled annual population estimates for the UK, now spanning more than 80 years, show a long-term increase.
Nest Box Challenge
Nest Box Challenge gathers valuable data on breeding birds by asking volunteers to monitor the birds in their garden through the breeding season
Nest Record Scheme
The Nest Record Scheme gathers vital information on the breeding success of Britain's birds by asking volunteers to find and follow the progress of individual birds' nests.
Contributions & findings
Norfolk Bat Survey
Norfolk Bat Survey offers anyone in Norfolk the opportunity to borrow automated equipment to record bats in the local area.
Contributions & findings
- Large-scale citizen science improves assessment of risk posed by wind farms to bats in southern Scotland
- Potential for coupling the monitoring of Bush-crickets with established large-scale acoustic monitoring of bats
- A novel citizen science approach for large-scale standardised monitoring of bat activity and distribution, evaluated in eastern England
- Bat-monitoring: a novel approach
Northern Ireland Lowland Breeding Wader Survey
Investigating whether Northern Irish lowland grasslands are supporting breeding waders.
Waterways Breeding Bird Survey
The Waterways Breeding Bird Survey is an annual survey of breeding birds along rivers and canals.
Wetland Bird Survey
The Wetland Bird Survey (WeBS) monitors non-breeding waterbirds in the UK.
Contributions & findings
- 3.75 million waterbirds are counted for WeBS each year.
- WeBS produces annual indices for 110 waterbird species or populations
- Species totals published annually for over 2,700 sites as open data on the WeBS Report Online
