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.
Victor is still settled in the gallery forest that he has been in for almost a month now. In 2017 he began his journey west on 9 March but he didn’t arrive at his current site until 14 February. It could be that we see him move west any day now.
Thomas is still close to the border with Cameroon and just to the east of the Afi Mountain Wildlife Sanctuary. It might not be too long before we see Thomas make a concerted move west.
Selborne didn’t hang around in Ghana. Having spent a week there he headed west again, 687km (426 miles) west into Guinea, overflying Ivory Coast on the way. Presumably he will stay here a little longer and prepare for his desert crossing. In 2016 he crossed the Sahara on 25 March and on 24 March in 2017.
