Lost Cuckoos

Browse the pages of all Cuckoos that have been previously tagged and are no longer transmitting. Every tagged Cuckoo gives us hugely valuable information. This includes information about when, where and how they perish.

You can read about all our lost Cuckoos below, or learn more about Chris or PJ, two exceptional Cuckoos which captured public imagination and revealed findings new to ornithology.

  • If you'd like to support this project and help us learn even more about why Cuckoos are in rapid decline, please consider making a one-off donation or sponsoring a Cuckoo.
