Tracking Cuckoos to Africa... and back again

We’ve lost over half the number of Cuckoos in the UK over the last 20 years.

Since 2011 we’ve been satellite-tracking Cuckoos to find out why. We’ve learned lots of vital information which could help us to understand our Cuckoos -  about the routes they have taken, 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.

Our Cuckoos have now started their outward journey from their breeding grounds in the UK. Follow them below as they make their way back to Africa.
