The title of first tagged Cuckoo back to the UK is still up for grabs, and Chris is close on the heels of the two leading Cuckoos. From his location in Morroco on 14 April he has flown 810km (500 miles), across the Alboran Sea and the Sieraa Nevada Mountains to a location south of Valladolid, Spain.
This is surprising, as during the 3 years we have been following him, this is the first time he has ventured to Spain, previously preferring to travel through Italy and France.
Skinner is currently the most northerly Cuckoo, but only just further than Waller. Skinner is about 140km (90 miles) directly north of Chris while Waller is 170km (100 miles) to the north-west.
