We are a non-governmental, non-campaigning organisation focused on securing the future for birds and nature.
We use our science, monitoring and data to inform good environmental decisions and inspire others with the wonder of birds.
The heart of BTO encompasses three key areas: Birds, Science, People.
We have been at the forefront of bird monitoring and research since 1933. We share our vast body of knowledge through blogs, masterclass articles, training courses and events, and more.
We also curate the data collected by BTO and partner organisations about the UK’s birds in interactive tools like BirdFacts and Birds on your Doorstep.
Our science is regularly published in peer-reviewed journals and official reports and statistics. Because we are a non-campaigning organisation, the evidence we produce is robust and objective, and can be used by anyone wishing to understand the natural world and how it is changing.
We actively share the data we collect with other non-governmental and governmental organisations, which use the information to secure protection for special wildlife sites, set conservation priorities, shape government policy and steer decisions over planning applications and new developments.
We harness the skills and passion of thousands of volunteers and members. With their help, we have been monitoring the UK’s birds since 1933, and have extended our coverage to include other wildlife too.
