The black-and-white barnacle goose flies here for the 'warmer' winter from Greenland and Svalbard. This epic journey was once a mystery to people, who thought it hatched from the goose…

Our most familiar fern, bracken can be found growing in dense stands on hillsides, moorland, heathland and in woodlands. It is very large and dies back in winter, turning the landscape orangey-…
