Birds, Science and People are the core of BTO, and our 90-year history is proof of the power of that approach. Our unique, long-term partnership between volunteer observers and professional staff, has afforded us a deep understanding of birds in a changing world. Only through the support of our members and volunteers can we, as a charity, continue to inspire people about birds and inform society through the evidence base that our science provides. We are fortunate to have an amazing and vibrant community around us, as our work continues to demonstrate.
