This is an exciting and ground-breaking project, but we still need funds to complete all the work planned. You can play a vital part in making this project a success – sponsor a Cuckoo today.

Sponsoring a Cuckoo is a really popular way to see first-hand the movements of this iconic migratory bird. In return for your support, we will send you regular updates detailing the latest news as the drama of the journeys of our Cuckoos unfold. Their stories are bound to amaze you and their feats are guaranteed to inspire you.
This is my first year following the Cuckoo’s journey and I would like to thank you for the happiness and pleasure it has given me reading your updates. I look forward to the next journeys. Amazing!
