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.

Sherwood is in Congo - 14 Nov 2018
On the 8 November we received a series of locations that showed Sherwood had moved out of Nigeria and that he was in the very northeast corner of Equatorial Guinea. Four days later he was in the Congo rainforest. During this time he has flown almost 1,500km (900 miles).
Selborne not hanging around - 14 Nov 2018
Since leaving Benin Selborne hasn't hung around. After a short stopover in Northern Gabon, close to the border with Equatorial Guinea, he has moved further south and east into Gabon. He is in an area of rainforest to the east of the Ogooue River, south of the town of Ndjole.
Raymond has moved east - 14 Nov 2018
During the last week or so Raymond has slowly moved east and south out of Burkina Faso. He is currently in Togo, very close to the border with Ghana, and in the Assouakoko Forest. During this time he has flown 580km (360 miles).
