British Trust for Ornithology
The British Trust for Ornithology has existed since 1933 as an independent, scientific research trust, investigating the populations, movements and ecology of wild birds in the British Isles.
Our speciality is the design and implementation of volunteer wild bird surveys, and our partnership between a large number of volunteers and a small scientific staff has proved to be a powerful, productive and cost-effective way of monitoring wild birds. They record wild birds systematically using survey methods developed by our scientists, who then compile the records and analyse them for publication. This work makes a direct and vital contribution to bird conservation, by enabling both campaigners and decision-makers to set priorities and target resources. It also provides a unique insight into the state of our environment and how it may be changing.
