Vanishing hedgehog ?

I read a letter in the Daily Mail the other day about the decline of the hedgehog. The fox was blamed as the predator and the letter writer had witnessed foxes killing and eating our little spiney friends. I am glad to say there were follow-up letters denouncing this and giving the true reasons, such as the loss of hedgerows, concreting and paving of gardens, over-use of insecticides and rat poisons. In gardens such as mine they thrive. Almost every night through-out the year several visit my garden, my infra-red cameras have recorded thousands of  such visits and often, as the picture shows, they share the food with the foxes, they have no fear of the fox and often eat together. The most that I have recorded is 2 foxes and 3 hedgehogs on the lawn together at any one time. I am considering buying some up-to-date infra-red equipment and get some really good pictures. Badgers are a bit of a problem for the hog as they can unfurl it when it rolls into a ball in defence. Fortuneately badgers don't come into my garden.
