Learning to be wild : raising orphan grizzlies

"I can't imagine a world without bears. For the past seven years my partner and I have been privileged enough to live for five months of the year in a remote wood-frame cabin we built in the South Kamchatka Sanctuary, Siberia.

This varied and beautiful landscape is home to the world's densest concentration of brown bears, formidable creatures who travel well-worn paths through the tundra".

This is the story of Chico, Biscuit and Rosie, three orphan grizzly cubs who were rescued from a Moscow zoo and taught to survive as wild bears in the South Kamchatka Sanctuary.

Charlie and Maureen Enns have studied bears in their natural Siberian habitat for the past eight years.

During this time they rescued the three orphaned cubs and created a home for them near their cabin in South Kamchatka.

The couple's day to day life with these three bears is captured in this unique record, which contains 176 full-colour photographs taken by the authors.
