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 learnt lots of vital information which will to help save our Cuckoos but, there is still more to discover.

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

Chris moves west at last - 31 Mar 2015

Chris is on the move! A good quality signal on 31 March placed Chris just inside the border of Ghana, showing that Chris had made his move west, albeit later than in previous years. Since the last transmission received on 21 March he has covered 1700km (1060 miles).  We are glad to see he is once again on his way. This will be the fourth return journey over which we will have followed him - we wish him a safe return! 

David in Sierra Leone - 27 Mar 2015

On the evening of 26 March a transmission received from David showed that he was on the move again and had travelled 650km (400 miles) further west. He is now in Sierra Leone, close to the border with Guinea. 

In both previous years he has also set off on his desert crossing from Sierra Leone but in both cases he arrived there in the first week of April. In 2013 he started his desert crossing on 15 April and headed to Mauritania while in 2014 he left on the 17 April but went slightly further west still, to Senegal, and then on to Morocco. 

Given his earlier movement this year, could he be the first Cuckoo to turn north and head home?

No further signals from Fred - 25 Mar 2015

Since receiving one transmission from Fred's tag on 5 March, nothing further has been received which details his location and he has once again dropped off the map, which shows only active Cuckoos within the last 10 days by default. We presume that, if all is ok, Fred would by now have moved to West Africa. We will have to wait to see where he is when further transmissions are received.
