Meet Lily, an eight-year-old wild black bear, described by some as 'the most popular bear in the world'. Why? Thanks to bear biologist Dr Lynn Rogers, from day one her life has been documented online.

Dr Rogers has a unique relationship with Lily and all of his study bears, feeding them by hand and walking with them in the Northwoods of Minnesota. But his methods have divided opinion, resulting in a bounty being put on Lily's head. With hunting season fast approaching, this is the latest and possibly most challenging chapter in her remarkable life.
