A female wild boar with piglet, Forest of Dean, Gloucestershire. Seeing such piglets running wild is still rare in Britain with wild boars only recently regaining a foothold having been hunted to extinction hundreds of years ago. Wild boar became extinct in Britain around, it is thought, the 13th century. There have been a number of attempts to re-introduce the species but boars didn't come back to Britain until the 1980s when wild boar farming began. Over the years escapees from these farms and animals parks have gone on to establish a number of new breeding grounds. Boars can now once again be found living wild in Kent/East Sussex, Dorset, Devon and Gloucestershire/Herefordshire. the photographer Andy Rouse documented one of the new boar colonies in the Forest of Dean in Gloucestershire as part of his work with the 2020VISION project.

Wildlife managers have not been able to positively identify the species of this bird after it arrived this month at Bosque del Apache national wildlife refuge in southern New Mexico. The refuge's manager, Aaron Mize, said it could be a hybrid-cross involving a crane. Without blood, feather and tissue samples, Mize said the bird will have to remain a mystery.
