Updates from our Cuckoos

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.

We have received no recent signals from Clement. His last position in Cameroon was further south and east than any of the other Cuckoos currently are - we expect him to move off in a north-westerly direction soon, when his tag should spring to life....

Positions for Kasper received overnight 6/7 March showed that he remains near Lake Volta. Lyster is also now in Ghana, just 30km (18 miles) to the SSW - this is the closest any of the Cuckoos have been to each other since leaving the UK.

Locations for Chris received yesterday (7 March) showed that Chris had moved 80km (50 miles) south-west and is currently in southernTogo, about 30km north of the coast and 10km from the border with Ghana.

A series of locations received for Lyster yesterday afternoon (7 March) showed that he had continued moving rapidly west and is now just north of Digya National Park in Ghana. He is currently 30km (18 miles) SSW of Kasper's latest location.

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.

 Twenty-four days ago Martin was in Congo, as we haven't heard from him since then we have to assume that he could still be in Congo. However, as all of our birds have 'disappeared' prior to moving north from Congo, we hope that Martin is doing the same, and wait with baited breath to see where he will pop-up next.

 We haven't heard from Clement for over ten days and must assume that he is still in southern Cameroon, feeding in deep cover in preparation for his next push north.

Since his last transmission on 16 February, Lyster has travelled 1,190km (740miles) from his last known position in Congo. He is now in Nigeria! A transmission from him at 00.49 on 5 March shows that he is currently in the Niger delta. Lyster is the fourth cuckoo to have begun his long journey back to the UK.

Chris provided the biggest surprise over the weekend. Having not heard from him since 19 February, it was a shock to find out that on 2 March he was in Cameroon. Two days later (4 March) and he is in Togo, 1,950km (1,210miles) northwest of his last position in Congo.
