cob

A cob is the term for a male swan. Swans are the largest waterfowl species, known for their long necks and graceful swimming. They primarily eat aquatic plants by dabbling in shallow water. Male and female swans, called pens, look alike. While often thought to be silent, swans can make various sounds, including hisses and grunts. They typically mate for life and engage in courtship rituals like bill dipping. The female incubates the eggs, while the male guards them. Young swans, called cygnets, are born short-necked and downy, and are cared for by their parents for several months.1
