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.

Latest News

Selborne has crossed the desert - 17 Jul 2018
Selborne left Spain on 11 July this year, heading almost due south into Morocco before drifting east into Algeria and then heading  west and on to southeastern Mali. He his in the same location, north of the capital, Bamoko, that he used as his post-desert stopover site in 2016. He moved west from this location on 23 July in 2016 but had arrived there six days earlier than this year. It will be interesting to see how long he remains here this year.
Cameron has moved south and east - 17 Jul 2018
Locations received from Cameron's tag during the early hours of 17 July showed that he was on the move, heading south and east into Nigeria. By breakfast he had reached the Sokoto River and was just south of the town of Kalgo. This will show on his map when it automatically updates.
Bowie moves again - 17 Jul 2018
During the last couple of days Bowie has moved south and east and is now in Chad and just to the northwest of Manda National Park. Since leaving the New Forest on 12 June he has flown 4,893km (3,040 miles). He has averaged 139km (86 miles) per day during his travels so far.
