Cuckoo Tracking Project
What have the Cuckoos taught us?
When the Cuckoo Tracking Project began, we knew very little about what our breeding Cuckoos did once they left the UK for the winter months.
Amost 100 tagged birds later, our new blog explores what we have learned and the questions we're still asking.
Help us follow Cuckoos on migration and discover why they are in decline
The Cuckoo is currently Red Listed as a Bird of Conservation Concern in the UK, due to its population decline.
Since 2011 we’ve been satellite-tracking Cuckoos to find out why they are declining. We’ve learned lots of vital information which could help us to understand our Cuckoos, such as how the different routes taken are linked to declines, and some of the pressures they face whilst on migration — but there is still more to discover.
We now need to look more closely at how dependent they are on, and how much their migration is linked, to the drought-busting rains of the weather frontal system known as the Inter Tropical Convergence Zone (ITCZ) as they move out of the Congo rainforest and begin to head back to the UK via West Africa.
- This project wouldn't have been possible without the amazing support from funders and sponsors. Read more about the project and find out how you can get involved.
- We have been able to share our expertise around tracking Cuckoos with other international studies, such as the Beijing Cuckoo Project.

2023’s Cuckoos are tagged and ready to go
BTO has fitted 10 more Cuckoos with satellite tags, allowing scientists and the general public to follow these incredible birds on their annual migration.
