A gloriously illustrated book bringing to life the remarkable nest-building abilities of birds around the world and the amazing shelters they produce. Birds play a crucial role in our ecosystem by controlling insect populations, pollinating plants, and spreading seeds. They are also incredible engineers, with the ability to build intricate nests to provide shelter and protection for their eggs and chicks. Birds have a remarkable ability to build complex--and beautiful-- nests. We're probably most familiar with cup-shaped bird nests made from twigs and grass, but this is just one of many designs that birds use to create a home where they can nurture and protect their young. Depending on their habitat and way of life, a bird's nest can float on water, teeter on the highest outcrop, or hide inside the trunk of a tree. In this beautifully illustrated book, young readers will discover the remarkable variety of nest-building techniques used by birds from around the world, and marvel at their ingenious use of materials--from soft feathers and cushioning moss to spiders' silk and sticky spittle.
