On the 18 March Martin remained in Ivory Coast but he has now been joined by Chris, who is around 100km (62 miles) away to the south-east.

 Martin's tag was picked-up at 20.02 on 15 March, which showed him in his previous location in Ivory Coast. He is still the most westerly Cuckoo.

Martin has been taking the 'tourist route' - by 9 March, he had moved south from Mole National Park to Bui Mational Park in western Ghana. Two days later, he had moved 140km (87 miles) west from there to Ivory Coast.  He is currently close to the town of Kamele and is about 80km (50 miles) south of Comoé National Park.

Since Martin's tag suddenly began transmitting on the afternoon of 6 March, we have received several locations that placed him in northern Ghana - although there was some uncertainty (and hence the locations are not shown on the map) we think the last locations received late that afternoon placed him in Mole National Park where the BTO/RSPB/GWS/Naturama 'Migrants in Africa' project worked during 2009-11. This makes him the most northerly Cuckoo of our five at about 9.5 degrees north.

After a silence of 24 days, at three thirty yesterday afternoon we received a location for Martin showing he was in northern Ghana, about 65km north of Tamale!  He had covered around 2,000km (1242 miles) from his location in Congo. This means that all five Cuckoos have now left Congo and are currently on their way back to Britain.
