Follow the life cycle of a bird as she builds a nest and lays her eggs and the pages fold out to create one big final image in this unique novelty book. Two little birds have found a perfect tree and are soon busy collecting twigs to build a nest. Readers can turn the pages of this unique format and see the nest take shape. Soon six little eggs are laid and the birds must keep them warm till they hatch. The unfolding pages create a big cicular nest, complete with hatching baby birds. Additional facts and information on how to encourage birds into your garden are included under the central flap.
