BTO Owl Appeal
We’re in the dark and we need your help. Owls play an important role in our environment. We urgently need your help to understand more about the ecology and population status of owls in the UK. As apex predators they sit at the top of the food chain and are therefore excellent indicators of the health of the countryside. We need a much better understanding of their population trends, how they use different habitats and how they interact with other species.
Cuckoo and Nightingale Appeal
Donate now to fund vital research to ensure Cuckoo and Nightingale don’t become sounds of the past.
Make our Science Count
Make a donation to help ensure that our voice is at the heart of post-Brexit decision-making on birds and their habitats.
