A little brown bear cub shows his doting mum that she is always on parent duty as he uses her as a scratching post. These adorable photographs of two playful bear cubs and their watchful mum were captured by American nature photographer D. Robert Franz, 56, on a visit to Lake Clark National Park, Alaska. 'What we see in these photographs is the interaction between the mother brown bear and her two cubs,' says D. Robert, of Cody, Wyoming.
