Express ran a story that William Hill has opened odds on tagged Cuckoos flying back from west Africa. It would appear David running at 2/1 (former winner 2013) is in front flapping towards Liberia on 31/03/15. Meanwhile Stanley 20/1 appears to have got lost and is heading south east again.

It also highlights that anyone can sponsor a cuckoo through the BTO.
