Charlie last to leave Europe
Larry continues onwards
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.
End of the line for Jake
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.
Silence from Ash
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.
No further signals from Cookie
We have received no further signals from Cookie. The data from his tag showed a low battery charge and although there is no evidence that he has died we think that this is likely. Dr Chris Hewson, lead scientist on the project visited northern Italy during the summer and found Cookie alive and well but in a location that held a very active Peregrine. Peregrines are known to take Cuckoos on migration and it is not impossible that this could have happened to Cookie.
Chris's journey ends in the desert?
We are still receiving poor quality signals from Chris that show he is still just north of the Tibesti Mountains in northern Chad. He has been here for almost four weeks and although we have no direct evidence that he has died, it seems unlikely that he would stay there for that length of time even though the area has recently received some rainfall. It may be that after over four years of following Chris's journey it may have come to an end.
Battery failure for Fred's tag?
No further signals have been received from Fred’s tag since 1 August. His tag has not been charging properly for several months and has been showing generally very low but erratic voltage. There is strong evidence that Fred’s tag has failed and nothing to suggest that he has died but it is unlikely that we will receive further signals to alert us to his progress.
Fred in Spain
A number of locations from Fred on 1 August showed that he had left France and was in Spain, just west of Madrid.
David crosses Desert
By evening on the 26 August, David was on his way south from Montenegro and by the early hours of the 29 August he had covered 1865km (1160 miles) and was transmitting from Libya. The latest signals, received yesterday, show that he had almost completed his desert crossing and had made it to Central Chad. Larry, Disco Tony, Coo and Vigilamus are all just a little further south within Chad. In previous years he has made it to Africa much earlier, on the 4 and 15 of August, although in 2013 we received transmissions on the 25 August.
Disco Tony south of the Sahara
Disco Tony is the latest our of tagged Cuckoos to reach Africa and attempt the desert crossing.
The last good signals received prior to this were from early August, and located him to the west of Milan, Italy in the area which has been afffected by recent droughts. Poor signals on the 18 August indicated he had left Italy and travelled 1765km (1100 miles), crossing over the sea to Africa to reach northern Libya. Since then he has covered a further 2120km (1320 miles) to reach central Chad. He is now south of the Sahara and hopefully will find suitable conditions to recover from this epic trip. Other Cuckoos have struggled to prepare successfully for the challenge given the conditions in Italy so we hope that Disco Tony has had more success and can continue onwards shortly.
