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 -  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.

Follow our Cuckoos as they move to and from Africa.

No signals have been received from Carlton for sometime. We know that Carlton was alive when his tag last transmitted but that it hasn't had enough charge to transmit since. 
No movement from PJ - 26 Jul 2017
PJ hasn't moved far but he seems to have found a river delta, where presumably there is water and vegetation at this time of year.
Victor in Burkina Faso - 26 Jul 2017
Victor is in Burkina Faso. Having only stayed for only a couple of days in Algeria before continuing south, Victor traveled 2190km (1360 miles), reaching south eastern Mauritania during the evening of 18 July, and continuing to fly east to Mali during the early hours of the 19 July.
