Chester and Dudley are the only two Cuckoos, from who we are receiving regular transmissions, who are currently within the Congo rainforest. We expect them to move north to the forest edge shortly as other Cuckoos have done.
During the last couple of days PJ has crossed the desert and is on his way back to the UK. A couple of poor quality locations received from his tag late in the evening on 16 April showed that he was crossing the Mediterranean east of the Strait of Gibraltar. We will have to wait until his tag powers on again late on 18 April to see where he makes landfall.
