BTO Cuckoo Tracking Project - Follow the birds
About the projectWe’ve been satellite-tracking Cuckoos since 2011. We’ve learned lots of vital information, such as how the different migration routes are linked to declines, and some of the pressures Cuckoos face whilst on migration, but there is still much more to discover.

About Birds in GreenspacesBirds in Greenspaces is a new, UK-wide citizen science survey of birds that use our public-access greenspaces. Public access greenspaces include places like parks, cemeteries, and playing fields. The varied habitat and management in these spaces means they play many important roles for both birds and people, particularly in urban areas.By finding out which and how many birds rely on and use greenspaces, and the importance of these spaces for people, we can use the findings to inform management guidance.
