Birds build nests using a variety of materials they find in their environment, such as twigs, leaves, grass, mud, feathers, and even man-made items like strings or paper. They use their beaks and feet to construct the nest, weaving the materials together to form a sturdy structure. The nests are typically built in trees, shrubs, or on the ground, depending on the species of bird. The shape and size of the nest can vary greatly depending on the bird's species and habitat.
