Updates from our Cuckoos

With no further news from Chris the Cuckoo, whose last transmission was from the middle of the desert, we have to conclude that he has sadly died. Chris was satellite-tagged in spring 2011 and we have been following his journey for the last four years as he traveled to and from Africa. See our celebration of Chris' journey and just how much he has contributed to our understanding of Cuckoo migration.

Since the last update, Stanley has travelled 700 miles to the Democratic Republic of the Congo. Stanley is now in the same area that he spent the winter of 2014/15 in, next to the River Congo.

Stanley has moved 370km (230 miles) southeast and has left Nigeria. He is now in northern Cameroon.

Charlie has carried on, apparently skirting the Tibesti Mountains where a number of our Cuckoos stopped this year for the first time, to make it across the desert. He is currently located in southern Chad.

Charlie, the last of our tagged Cuckoos still in Europe, has finally left and crossed over the sea from his last location in Greece to reach Africa! We were beginning to worry that he was still in Greece but signals on the evening of the 14 September show he was in Libya. Since then he has been making his way south across the desert. 

Looking back at previous years, the only two Cuckoos to arrive in Africa later were BB on the 15 September 2014 and Lloyd on 3 October 2012. Both these Cuckoos also took the easterly route, heading to Libya but from Italy instead of Greece, as Charlie has done. 

Since the 10 September Coo has moved 810km (500 miles) further south, flying over Central African Republic.  By 13 September he had made it to northern Democratic Republic of Congo and areas of lowland forest. He is the first of our tagged Cuckoos to make it to the Congo Rainforest this year. 

After a few days, Larry has continued south and left the Tibesti Mountain area. He is now close to Lake Chad and safely across the desert.

The last signals we received from Jake back in June showed that he was still in central France. No further signals have been received since. Looking back, the tag temperature was unusually high during these tranmissions, indicating that Jake had died. We have no idea what the cause of death might have been.

A series of poor quality locations from Ash during early July showed that he was moving around in Croatia but we have heard nothing since. The tag data showed that he was alive when we last heard from it so it’s possible that his tag has failed.
