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

Small movement from Selborne - 03 Jan 2018
Selborne has made a small movement north within Gabon of about 95km (60 miles) to an area he visited last year, just south of Waka National Park. Last year he moved north again towards the end of January and was in Ghana by January 31 so it might not be too long before we see some big northward movements from him and our other Cuckoos, into west Africa. 
PJ moving north - 03 Jan 2018
PJ is already on the move northwards. From Angola on the 22 January, he travelled 755km (470 miles) in a north-easterly direction to get back to Gabon by the evening of 26 December. In 2016/17 his behaviour was similar, heading north from Angola to the centre of the Republic of Congo in the second week of January and moving on again north by the end of January. It's the beginning of his long journey home.
Peckham in Gabon - 03 Jan 2018
By the early morning of January 1, Peckham had arrived in Gabon, 570km (355 miles) south-west from his last location in the Central African Republic. His new location in the Haut-Ogooue region is just 55km (35 miles) away from PJ who has moved north from Angola, where he has spent some of this winter. Peckham has spent the last two winters in and and around this area in Gabon so we don't expect much further movement from him, now that he is in his wintering grounds.
