Jake has left Cameroon and made it to the Congo rainforest in Democratic Republic of Congo a further 1650km (1020 miles) south-east. He is now in the swamp forests close to Lake Tumba. 

Both Sherwood birds 134957 and 134955 have moved over 700km (470 miles) east from their locations in Burkina Faso in the last few days and are now in northern Nigeria. This leaves just Chester in Burkina Faso who becomes our most westerly bird by over 960km (595 miles). 

Cuckoo 134597 has moved south, travelling 485km (300 miles) from Mali to Nigeria. He is now only 100km (60 miles) away from Skinner's location.

134957 arrived in Mali in the middle of August and has remained there since. He is the most northerly of all the Cuckoos within Africa and we would expect him to move further south and east soon, towards the Congo rainforest. 

On 10 August 134957 was north-west of Toulouse in southern France. Signals received on 14 August indicated that he had travelled 800km (500 miles) south from there and crossed the Balearic Sea to reach the Algerian coast.  He continued to travel south through Algeria and by 17 August was in Mali, close to the area where Skinner paused his journey for a short time. We will have to wait for further signals to see whether 134957 waits here or pushes on to complete his desert crossing.
