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.

Raymond had made it! - 08 Aug 2018
At 04:05am on 8 August we received a series of good quality locations from Raymond's tag that showed he had successfully completed his desert crossing and was on the eastern edge of the Reserve de Faune du Ferlo Nord. He is the last of our Cuckoos to cross the desert this year.
Carlton II is in Senegal - 08 Aug 2018
We hadn't heard from Carlton II's tag for over a week and wondered what he might be doing. We now know that he was crossing the Sahara. Recent locations show that he completed his desert crossing around the 6 August; on this date he was in western Senegal. We know that in the days running up to 6 August, fairly strong easterly winds were blowing in the desert and it seems that Carlton II got caught up in these and was drifted west. He has already begun heading east and is now in eastern Senegal, in the Foret de Diambour.
Sherwood is crossing the desert - 06 Aug 2018
During the evening of 5 August Sherwood was crossing the Sahara and was in the Akchar Desert, to the west of the Richat Structure, also known as the eye of the Sahara. The terrain here is barren and the daytime temperature is currently around 40 degrees. The winds are fairly strong in this part of the desert right now and are coming from the east. This will cause Sherwood to drift to the west. If successful in his crossing, he may well join Thomas and Lambert in Senegal.
