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 -  about the routes they have taken, 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.

Our Cuckoos have now started their outward journey from their breeding grounds in the UK. Follow them below as they make their way back to Africa.

161324 in Angola - 28 Oct 2016
Having spent almost a month in Cameroon, 161324 has moved south, a long way south. Locations received from his tag on 26 October showed that he was in northern Angola just to the south of Cumbo and 1,143km (710 miles) south of his location in Cameroon. He may well spend the winter here.
Markoo heads for the Congo rainforest - 27 Oct 2016
On the 19 October, Markoo was still in Nigeria but over the last week or so he has moved south. By the 20 October he was in Cameroon, by the 22 he was transmitting from eastern Gabon and on 24 October signals were received from the Republic of Congo, just south of Kelle.  He is now in the Congo rainforest and we will have to wait to see whether he stays here or moves further south still. We currently have three Cuckoos in Angola, 700km (435 miles) sosuth of Markoo's location.
Bill leaves Nigeria - 27 Oct 2016
By the 25 October Bill had left his last location in Nigeria and was on the move, heading in a south-easterly direction and passing to the east of Onitsha. Signals on the 26 revealed he had continued onwards, leaving Nigeria, and had made it all the way to Gabon. He is now to the south of Lvindo National Park. Since leaving Nigeria, Bill has flown 1,000km (622 miles) to reach his current location. It is likely that he will move a little further south yet.
