There is a baby Cuckoo in my garden being fed by a small Dunnock

This video shows a baby Cuckoo 8 days out of the nest being fed by his/her surrogate parent, a Dunnock. The Cuckoo had been taken from the nest by a Magpie but was rescued by the quick action of my wife. The Cuckoo seems unharmed and is now 10 days out of the nest and still being fed by the Dunnocks also is flying short distances around the garden.
