Each year, thousands of people from all over the UK kindly donate to BTO to help fund our research and monitoring of the UK's bird populations. The data and insight from our work provides crucial evidence for the conservation of bird species and habitats. If you have a question about your donation or how to donate, please email fundraising@bto.org.
Donate to an appeal
Our appeals are focused on key areas of our work. From seabirds and Starlings to inspiring BTO Youth, fund an appeal that matters to you.

Monthly and one-off donations

You can also set up a standing order for your monthly donation by completing our Standing Order Form and sending it to us by post.
One-off donations

Other ways to donate
Use PayPal
Make a monthly or one-off donation on PayPal with a debit or credit card – even if you don’t have a PayPal account.

You can also choose to make a card payment over the phone by calling our head office on 01842 750050.
Send a cheque
Make your cheque payable to British Trust for Ornithology and send it to: The Fundraising Team, BTO, The Nunnery, Thetford, Norfolk, IP24 2PU
Please note: processing and responding to donations and correspondence sent to us by post may take a little longer than online donations. Please email fundraising@bto.org if you have any urgent questions about donating.
Remember to Gift Aid your donation
If you are a UK tax payer, fill out a declaration form and send it back to us. We can then reclaim 25p out of every pound from the government.

In-memory donations
A gift to BTO in memory of a loved one is a wonderful way of celebrating their life and their love for birds and ensuring that future generations can enjoy nature too.
You can also make a tribute to your loved one in our online Remembering a Loved One page, with the option of donating in their name.
For other ways to make your in-memory donation, including arranging Funeral and Memorial Service Collections, visit our In-memory giving page.

Please email our Legacy Manager, Sam Rider at sam.rider@bto.org about the donation so we can say thank you and provide a receipt for your records.
