Illustrations of a lesser-known tale by the brothers Grimm. The wolf and the bear are walking through the forest and they hear the most beautiful birdsong. Believing it is the king of the birds, the bear is eager to see the opulence of the royal nest but is shocked to find it is ordinary -muddy twiggy and feathery. Insulting the indignant willow-wren chicks leads to a war between mammals and flying creatures. Who will win?
