Bold lines, soft shapes, and happy colors form the birds in BirdWingFeather. On the right-hand page appears a painting of a lovely bird against a colorful sky. On the left-hand page appears a detail set of the painting?some details children will be able to easily recognize, while others might prove to be a bit more challenging. A bird?s wing, an eye, a triangular shape, or a gentle curve?these shapes and colors will appeal to even the youngest viewer. Author Siri Schillios provides a charming introduction to this elegant exercise in seeing.
