Welcome to British Trust for Ornithology
We are a Registered Charity, working to secure the future for birds and nature, using our science, monitoring and data to inform good environmental decisions, inspiring others with the wonder of birds and empowering them to work with us. Our priority is to make a positive impact for birds and people, using our strong and objective science in partnership with others. We strive to work sustainably and to welcome everyone.
A unique partnership, needed now more than ever
Our unique, long-term partnership between volunteer observers and professional staff has afforded us a deep understanding of birds in a changing world. Our science and data are telling us loud and clear that nature is in trouble. The urgency with which we need to ensure a more secure future for nature demands us to do more with our wealth of data, knowledge and expertise. Remaining rooted in science, we are focused on finding solutions and making a difference for both birds and people.
Waterbirds report published
