Waller is almost back. Having left his last location in Spain, he flew over the Cantabrian Mountains and across the Bay of Biscay and by 29 April he was in Berson, just north of the port city of Bordeaux on the Garonne River in the Gironde department in southwestern France. The latest signals shows him a further 550km (340 miles) further north and, after a brief rest on the Channel Islands yesterday evening, he continued on his way again and the last transmission was over  the sea.  The next signals should reveal that he has made it to land and will be on, or closer to, his tagging ground on the Isle of Skye. 

48 hours after the last signal, Waller had made it to Europe and was in north-western Spain, just west of the city of Valladolid, having travelled 680km (420 miles). He continued for another 90km (60 miles) and is now north-west of Leon and almost as far north as Skinner, who is about 85km (55 miles) to the north-east. Chris is also not far behind! Who will be first back to the UK?  

Waller has certainly had a  busy weekend!  By midday on Friday 11 April he had moved 590km (365 miles) to southern Mali , just south of the desert.  The next signal received was late on the 13 April which showed him in 2265km (1410 miles) further north, just inside the border of Morocco, having successfully crossed the desert! He continued moving onwards through the late evening and early morning of the 14 April, overflying the High Atlas mountains and covering another 450km (280 miles). By 3am he was just east of the northern city of Tangier (this point is not yet shown on the map). He is the second of our Cuckoos to have crossed the desert, but Chris was a close third! 

Waller had been in the west of Ivory Coast but has backtracked about 330km (200 miles) in to centre of the country and is now in the protected area of the Parc National d'Abokouamekro, to the west of Lake Kossou, the largest lake in Ivory Coast. Presumably feeding conditions weren't good in his westerly location and so he has moved on to find somewhere more suitable. 

Waller has continued a further 515km (320 miles) west and is now in the west of Ivory Coast, close to the borders with Guinea and Liberia.
