Chris is the only tagged Cuckoo that has provided data for three consecutive years. Chris has given pioneering insight into Cuckoo wintering grounds, migration routes and speed of travel. Find out more about why we're celebrating Chris

Chris returns to breeding grounds again - 29 Apr 2015

Chris has returned to the area around the Norfolk/Suffolk border where he was first tagged in spring 2011 and has spent each subsequent summer. 

Since leaving our shores in 2011, Chris has flown over, or visited, twenty-eight different countries, crossed the Sahara Desert eight times and reached speeds of up to 60mph. 

Dr Chris Hewson, lead scientist on the project at the BTO, said, “Chris was one-year old when we fitted the satellite-tag, which makes him five-years old now, and quite an age for a Cuckoo; the oldest we have on record is almost seven. The tag was also given a life of two-to-three years, so that is getting quite old too. We had everything crossed for Chris to make it back again this year and give us another complete migration route, and he hasn’t let us down.”

Chris returns for fourth time - 27 Apr 2015

Chris is back in the UK once again! From western Spain he has covered 1080km (670 miles), travelling over France and the English Channel to reach a location in the Isle of Wight by the 26 April.  He still has a little way further to go yet to reach his breeding grounds which are to the north-east, in Norfolk. This is the fourth return trip of his that we have been able to follow since he was tagged in 2011.  

Chris in Spain - 22 Apr 2015

Chris continued on his desert crossing from Mali, travelling a further 2500km (1550 miles) to reach northern Spain. He is now west of Zamora, a city in Castile and León region and is furher north than Derek, Dudley, David or Stanley. 

Chris crossing the desert - 20 Apr 2015

Over the weekend we received signals to show that Chris had embarked upon his desert crossing and was on his way north over Mali, 1345km (835 miles) north of his last location in Ghana. We will have to wait for further signals to see whether he has made it safely across.

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!
