The British Trust for Ornithology (BTO) is a UK charity that focuses on understanding birds and, in particular, how and why bird populations are changing.
Our vision is of a world where people are inspired by birds and informed by science. We strive to achieve this vision by harnessing the skills and passion of thousands of volunteers to advance our understanding of ornithology, in particular, through our bird surveys and schemes. We combine the resulting scientific outputs with interesting stories and powerful images to engage more people in this work and to inspire people to take action. Working in partnership with volunteers we have been monitoring the UK’s birds since 1933 and have extended our coverage to include other wildlife too.
We are a non-campaigning organisation and our aim is to conduct all of our work with the highest scientific rigour in order to produce robust evidence that can be used by anyone wishing to understand birds, other wildlife, their habitats and how different interventions may affect them.
