Satellite Tracks Cuckoos' 5,000km Journey

The migration routes of 5 British Cuckoos have been tracked by Scientists using tiny satellite-tracking tags. The bird's 5,000km journey began from East Anglia and all 5 have now reached Africa & 4 of the birds crossed the Sahara desert, one of the major sources of mortality for many migrants. The birds were distributed across 3,000km of the continent, from Morocco to Chad. It is thought that the birds would continue to fly a further 1-2,000km. Cuckoos are one of several migrant species declining in Britain so the team are keen to discover what environments the birds rely on and where they stop off to feed on their long migration.
