Chris remained in the east of Ivory Coast until at least 6 April. In the late afternoon of the 11 April, a series of transmissions revealed he was on the move and was in Mauritania, flying over the El Djouf Desert at the western edge of the Sahara, having already covered 1525km (950 miles) from his previous location.
Just north of the El Djouf Desert, he then changed course to head north-east, arriving in northern Morocco in the early hours of the 14 April, shortly after Waller also arrived in Morrocco having completed his crossing. This makes Chris the third of our Cuckoos to cross the desert successfully and is the third return desert crossing over which we have eagerly followed his progress. This year, he seems to have ended up much further west than after any previous crossings. He was tagged in the first year of the project and is the only remaining bird from the original five tagged. Over the three years, he has helped us to learn amazing new things about Cuckoo Migration and we hope that he continues to do so!
