How does a swan build it nest?

A swan builds its nest using a variety of materials, including reeds, grasses, and other vegetation, which it gathers from the surrounding area. The female swan typically constructs the nest, shaping it into a mound to provide insulation and protection for the eggs. She often lines the nest with down feathers to create a soft, warm environment for the eggs and cygnets. Once completed, the nest is usually located near the water's edge to facilitate access for the swans and their young.
