We run regular fundraising appeals to support our research and engagement priorities, and thanks to thousands of generous donors, our work has had a huge impact for birds and for people.
Our appeal-funded research is often published in peer-reviewed scientific journals and contributes to conservation across the UK. Browse the list below to find out more about the work funded by each past appeal.
If you would like to find out more about any of our appeals, please email fundraising@bto.org.
