WILD LIFE IN SEVERN ESTUARY 35 



the vestige of a feather, the young cuckoo begins 

 to sidle up to one of its fellow-occupants of the nest 

 and to lift it on its peculiarly shaped flat back. The 

 effort continues for long, and there can be no doubt 

 from the beginning about its deliberate intent.
