Over the course of the 1 March, Waller headed further west from his position just north of Lake Volta, travelling 465km (290 miles) and flying across the middle of Ghana. He arrived in Ivory Coast in the late afternoon and was 90km (55 miles) inside its border with Ghana.  At the moment he is 1300km (810 miles) further west than any of the other Cuckoos. Ken moved over the weekend and is officially in West Africa now. 

Waller has become the first of our tagged Cuckoos to move to West Africa!  The last signal placing him in Cameroon was received on 20 February and by the 27 February he had travelled a huge 1445km (900 miles), flying over Nigeria, Benin and Togo to reach Ghana. The latest signals reveal he is in eastern Ghana, 85km (52 miles) north of the northern edge of Lake Volta. 

This is the first return migration that we have followed for Scottish Cuckoo Waller but it's interesting to note that last year the first Cuckoo to move west was Chance, another of our Scottish Cuckoos. He also spent a few weeks in Cameroon before moving to Lake Volta in Ghana around the 25 February - very similar timing to Waller!  This timing does raise fresh concern that something has happened to either Chance, or his tag, as we have not received signals since 4 December and, given his timings last year, he should be on the move. 

Waller is still in the location in Cameroon , where he has been since early February. We last heard from him around lunch-time on 20 February. He is currently still one of the most northerly Cuckoos, along with David and Chris, who has recently moved north. 

We've received transmissions from Waller's tag which reveal that he is now in Cameroon, 390km (245 miles) further northwest than his last known location in Congo. He is moving closer to the edge of the block of the Congo Rainforest but still has a little way to go before he gets there. Only David is further north than Waller now. 

Since his stop in the Likuoala Aux Herbes area, he has continued another 88km (55 miles) north-west, and as of 12 January was just 9km (6 miles) from Norfolk Cuckoo, Derek.
