A PAIR of intrepid travellers are back in England after an African adventure.
But rather than a couple of lobster-skinned Brits, this pair are Chris and Lyster, two cuckoos fitted with tiny tracking devices.
The pair have been as far south as the Congo on their travels, having been tagged in Thetford Forest.
Graham Appleton, from the British Trust for Ornithology, said data from the pair would allow experts to see why the cuckoo population has halved in recent years.
“It’s been fascinating to see under which conditions they can migrate and this spring has been so grotty that it has meant they are back here a week or two later,” he said.
A further study, set to involve cuckoos from Scotland, will enable the BTO to compare findings with the Thetford study.
Three other birds were tagged in the study, one of which, Clement, died in March in Cameroon.
