BTO is the leading charity monitoring the wild birds of our gardens and wider countryside. Our rigorous scientific approach underpins policy decisions and conservation action at the highest levels.

We are committed to using the best evidence to inform decisions affecting birds, and to sharing our knowledge to inspire more people to engage with science and with the bird-life around them.

Sharing our passion for birds, our supporters make an enormous difference to what we can achieve. Tens of thousands of volunteers dedicate their time and skills to collecting data for our cause. Those that generously fund our work enable BTO scientists to harness this data to address the pressing issues that the UK’s birds face.

Legacies make up more than a quarter of the income we receive to fund our vital research.
