All five birds have reached Africa and are spread across some 3,000km of Africa. They started their journeys from the same breeding area in the UK in June where they were tagged and fitted with trackers.

Two are in southern Chad, one is in northern Nigeria and the fourth one is in Burkina Faso. One cuckoo is lagging slightly behind the rest and has made it as far as Morocco.

The Cuckoos are one of several migrant species declining in Britain.
