Woodpecker photo sparks debate

The image of the wide-eyed bird and its stowaway was taken by photographer Martin Le-May at a reserve in Essex. Mr Le-May was walking at the Hornchurch Country Park with his wife, Ann, in the hope of showing her a green woodpecker.
After hearing “distressed squawking” he says he spotted the bird with the small mammal on its back, and took a series of photos.
