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.

PJ moves east - 26 Aug 2016
Since crossing the desert and arriving in southern Mali, PJ has continued east along the southern edge of the desert and is now in neighbouring Niger, close to the border with Nigeria.
Peckham still in the Po Valley - 26 Aug 2016
Peckham is still settled in the stopover site that he used last year, however, he has lingered for almost a month longer this time. We are not sure why this is the case as this is only the second migration that Peckham has undertaken wearing a satellite tag. It might be that last year was unusual, or indeed that this year is the unusual one, so it is hard to draw conclusions at this stage. We do know that in 2015 the region suffered a severe drought which might have moved Peckham on early, only time will tell what is a normal departure date for him.
Markoo crossing the Sahara - 26 Aug 2016
A location received in the early hours of 25 August showed Markoo on his way across the Sahara. He was in central Algeria and just about halfway through the desert crossing. However, we received a poor quality location around breakfast time on 26 August that suggests he has made it across and is on the southern edge of the desert. We will have to wait for better quality locations to confirm this. Fingers crossed for Markoo.
