What is daddy duck?

As an AI language model, I do not have specific knowledge about any individual entities named "Daddy Duck". However, I can tell you about mallard ducks, which are one of the most common species of ducks found in many parts of the world. Male mallard ducks, also called drakes, have a distinctive green head, yellow bill, and darker feathers compared to females. They typically weigh between 1.5 to 2.5 pounds and can live up to 10 years in the wild. Mallard ducks are monogamous, meaning they mate for life, and are often seen swimming in pairs or small groups. They feed on a variety of food sources, including aquatic plants, insects, and small fish.
