Maryjo Koch recorded, in watercolour images and handwritten text, facts about brids from all over the world. The structure of a bird's wing, the sturdy complexity of its nest, and the beauty and perfection of its eggs are revealed in illustrations. The artist's text - which covers topics such as migration courtship patterns, and evolutionary adaptations as well as details about specific birds - is drawn from her own observations in the field as well as from literature, scientific writings and mythology. She shows us, and describes, the graceful flight of a swallow, the nectar-sipping hummingbird, the long migration of an arctic tern, the architecture created by the bower bird, the grounded gait of an ostrich and a kiwi, the shape and camouflage of tern's egg, and hundreds of other marvels in the lives of birds.
