Five Flew Over The Cuckoo's Nest
The British Trust of Ornithology has begun to track the migration route of five different British cuckoos with tiny satellite tracking tags. After catching and tagging the birds in June, the trust’s team of scientists will now follow the birds as they migrate to Africa. All the birds have now arrived in Africa, however, despite the fact that they all started their journey in the same breeding round in East Anglia, they are now spread across an area of almost 2000 miles of Africa. Their tags automatically switch on once every two days for 10 hours. They send off a radio signal revealing their whereabouts, which is picked up by a satellite.
According to one of the scientists, "The bird that has travelled furthest, Chris, has already flown almost 5,000km to Chad. We're expecting him to go further than that - possibly as far as 6-7,000km."
Crossing the Sahara is one of the major sources of mortality for migrating birds, so the team is relieved that almost all the birds have made it safely across the desert.
