It looks likely that either Ken has perished in Ivory Coast or the tag is no longer attached. The tag temperature is now fluctuating with the day and night time temperatures, rather than remaining consistant with body temperature as it should. It looks like we will not be following Ken across the desert and back to the UK. 

Ken had moved 100km (600 miles) by the 14 March and was just inside Ivory Coast. Waller and Derek are also in Ivory Coast, but further to the west.  

Ken has moved a further 380km (235 miles) north-west within Nigeria but is some way behind Derek, the third Cuckoo to move in to West Africa, who is now in Ghana.  

Ken has moved 200km (120 miles) from his last position in Cameroon and into Nigeria over the weekend. He is now officially in West Africa and is the second Cuckoo to move this far west this year.  

Ken is still close to Mount Cameroon, the area he arrived in on 13 February. As he is currently our most westerly Cuckoo, will he be the first to head into West Africa?
