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

Fred returns to the UK - 21 May 2015

Freds last location was in Morocco in early May but since then he has travelled across mainland Europe and yesterday arrived back in the UK, at his breeding site in Sherwood Forest. He is the tenth tagged Cuckoo to return this spring.   

Chester returns to the south of England - 12 May 2015

By the 11 May Chester had covered the 1500km (930 miles) from his last location in Spain and returned to his breeding grounds at Ashdown Forest in Sussex, becoming the ninth of our tagged Cuckoos to make it back to the UK.

No signals from Emsworthy - 6 May 2015

No further signals have been received from Emsworthy's tag since 19 March. He was still alive when we last heard from his tag - but the charge was very low. We may well here from it again after he's crossed the Sahara but it's possible the battery will have degraded too much for that to happen.
