Sayaan moves south
Sayaan has flown 350km (217 miles) south-west from Chad to Central African Republic (CAR).
He is now 13km north east of the town of N'Délé in CAR.
Joe reaches the Congo
Earlier this week, Joe left southern Chad and flew 930km (578 miles) south to the Democratic Republic of Congo.
He is currently 300km north-west of Torc, on the banks of the Busira river in the rainforest of the Congo Basin.
George reaches the Congo
A new update received this morning (6 October) from George's tag showed that he has flown 673km (419 miles) south from his last location in Central African Republic and has reached the Congo Basin.
At 9am this morning he was half way between Cuckoo Joe to his north and Trent to his south.
Cuach Torc reaches the Congo
Cuach Torc was the first of our tagged Cuckoos to reach the Congo wintering grounds this year, arriving on 20th September.
Since then has has remained in the same area, deep in the rainforest of Salonga National Park in the Democratic Republic of the Congo (DRC). This is Africa's largest tropical rainforest reserve, at 3,600,000 hectares it is more than half the size of Wales. This area is very isolated and only accessible by boat.
Hopes fading for Cuach Cores
Cuach Cores' tag is still transmitting loud and clear from a location in the countryside south of the town of Arsac, just north of Bordeaux, France.
Although we don't have any conclusive evidence that Cuach Cores has perished, the fact that he has spent so long in the same location and is so far behind the tagged Cuckoos makes us fear the worst for him.
KP visits Central African Republic and Chad
Joe pushes south in Chad
Trent pushes east into Nigeria
George moves south into the Central African Republic
George is the first of our tagged birds to begin the final leg of his journey towards his wintering grounds in the Congo Basin.
He has flown 770 km (479 miles) south, taking him out of Chad and into the Central African Republic (CAR). He is now in dense rainforest in south west CAR, approximately 190 km (118 miles) west of the capital Bangui.
