This image of a weasel mounting a woodpecker in Hornchurch Country Park is one of the greatest nature pictures ever taken.
"It's been everywhere - even on the Ellen Degeneres show - so I wanted to shine a light on Hornchurch and show we've got a sense of humour," Cross said. "I bumped into some people when I was putting it up and I realised people here are actually really proud of the photo. Hopefully the council will let it stay up and it'll become a photo opportunity in the park".
Apparently it is not photoshopped with Cross and his friends using their work contacts to create the sign and a scaffolder to put it up.
Martin Le-May took the image of the weasel riding the green woodpecker last week while on a walk with his wife, Ann.
“Just after I switched from my binoculars to my camera the bird flew across us and slightly in our direction; suddenly it was obvious it had a small mammal on its back and this was a struggle for life,” Mr Le-May said of the image.
The woodpecker survived its encounter with the weasel, with Mr Le-May saying he believes he and his wife distracted the predator allowing the bird to fly off.
