Cuckoo decline finally mapped
Forty-two tiny tracking devices fitted to cuckoos in the UK may have solved the mystery of the birds' decline.
Britain has lost more than 70% of its cuckoos in the past 25 years.
A study tracking their migration has now revealed that the birds have two migration routes - and one appears to be more risky than the other.
The findings are published in the journal Nature Communications.
