Different kinds of birds build different kinds of nests. Some nests look like cups woven out of grass, weeds, twigs, and leaves. Some are made with grasses and mud. Some look like little hanging bags and others like piles of sticks. The nests are usually lined with soft grasses to make a comfy spot for eggs and babies. Ask: What do you think this nest is made out of? Where is the nest built? Do you think it is a safe nest?
