A "Bird's Nest" is a structure built by birds to hold their eggs and raise their young. Nests can be made from various materials, including twigs, grass, feathers, and mud, depending on the species of bird. They are typically found in trees, shrubs, or on the ground, providing shelter and protection from predators. Different types of birds create different kinds of nests. For example, sparrows often build cup-shaped nests, while eagles may construct large nests high in trees. The design and location of a nest are crucial for the survival of the chicks, as they need safety and warmth during their early development.
