By 30 November, Chester was on the move again, having spent roughly 14 days in his previous location in Nigeria he then headed south-east to a location close to the border of Cameroon. From here he has travelled 640km (400 miles) to Gabon, and finally arrived in the Congo rainforest area on 2 December. he is the last of all the tagged Cuckoos to arrive there. In 2013, BB was the last of the Cuckoos to arrive in the rainforest, arrving on 7 December.
Chester has continued on east from Ghana, over Togo and Benin, to make it to Nigeria by the morning of the 16 November. He is now close to Lokoja, a city which lies at the confluence of the Niger and Benue rivers, and is moving closer to the Congo rainforest in which all our other active tagged Cuckoos are in.
Early yesterday evening we received signals from Chester's tag to show that he had moved further east and south, leaving Ivory Coast and crossing over into Ghana. He is now close to Lake Volta, an area we have seen the Cuckoos use before, although previously this is normally on their spring migration as they head north to return to the UK.
In the last few days, Chester has moved 445km (275 miles) south from his location in the north of Burkina Faso and he is now in Ivory Coast. He is still very far west of all the other Cuckoos so it is perhaps a little surprising that he has chosen to move south rather than east. He has, however, moved to Comoé National Park , a World Heritage Site due to the diversity of plant life present around the Comoé River including pristine patches of tropical rain forest that are usually only found further south.
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).
