I thoroughly enjoyed the programme. It’s taken a long time to research the Cuckoo and well worth making the effort.
They are so cunning, and have to be to survive. I felt really sorry for the Reed Warbler though and wanted the Cuckoo chick to fall out of the nest

but then it made me feel sorry for it – confusing my emotions, but that’s wildlife and I hope the Cuckoo survives in the future. A very good programme!
