There have been no movements of note from our Cuckoos in the last few days. Transmissions have been received from Indy and Chance today and Lloyd, David, Wallace, Roy, BB and Chris in the last few days. Hopefully there will be more to report after the weekend! 

By the early morning of 7 September Roy was already 141km (88 miles) south of his previous location and was moving SE along the border between Chad and Sudan. By mid-morning on 9 September he had covered a further 251km (156 miles) and was in southern Sudan, 50km east of the border with Central African Republic and 106km (66 miles) north of the world's newest country, South Sudan. Like Indy, he is slowly moving south into less arid areas, following the band of rains produced by the Inter-Tropical Convergence Zone as it moves south. 

From his position just inside the Nigerian Border, Indy had moved 204km (127 miles) SE into the Yobe state by the evening of 9 September.  His current location is 35km (22 miles) east of Potiskum, in what appears to be an area of what is known as tiger bush, where scrubby woodland is interspersed with bands of un-vegetated rock . As expected, he is moving slowly into areas of higher annual rainfall, following the band of rains that is moving south as autumn progresses. 

Locations received from Lloyd’s tag on 31 Aug still place him in west Italy. There has been no further information on Iolo but both Indy and Davids’ tags have transmitted in the last few days. David is still in Chad whilst Indy remains in northern Nigeria.  

We have received nothing further from Mungo since the 2 August.

We have received signals from both BB and Roys' tags which show that they remain in the east of Chad, close to the border with Sudan. They are just 48 km (30 miles) apart and are the two most northerly of the tracked Cuckoos in Chad.

Locations received from Chance on 4 September show that Chance remains east of Lake Chad. 

Unconfirmed signals suggest that Wallace has moved 30km (18 miles) northeast, placing him 7 miles west of the shores of Lake Garda. 

Chris’ tag transmitted this morning from a location 52km (32 miles) south of his previous position. He remains in Chad but is only around 195km (120 miles) north-west of the border with the Central African Republic, where he moved to last winter after leaving Chad. 

No further signals have been received for John or Reacher since their last locations in France and Spain respectively. Taking a look back at the temperature data,  the last few messages received for each tag show a lot of variety associated with time of day - i.e. cooler in the early morning and reaching over 30°C in the afternoon. Temperatures prior to that had always been higher than 30°C, even when the Cuckoos were in Britain. This suggests that the bird’s body temperature wasn't influencing the tag's temperature much during these signals and does, unfortunately, support the idea that they may have perished.
