Even though they have long mouths that look like "beaks", they are not considered "beaks".
How they hunt for food ? The duck's mouth is called a "bill". Normally, it is broad and flat and has rows of fine notches along the edge called "lamellae". The lamellae helps the duck to grip its food so that it will not slip off. However, ducks bills come in different shapes and sizes. The shape of the bill and body features will determine how the duck hunt for its food. Ducks which have broad beaks, sift their food for insects, snails and seeds from the mud. These are called the shovelers. The Northern Shoveler is an example. Female Northern Shoveler Male Northern Shoveler Some ducks have long and narrow beaks. The narrow beaks are also covered will saw-like edges which help them to grab fish. Sea ducks usually have this kind of beak. Sea ducks are also divers. Examples are the Mergansers, Eiders, Harlequins, Goldeneyes and Buffleheads. Some ducks do not dive for food. Their beaks are broad and short. They are called dabbling ducks or dabblers. They eat plants, seeds, grasses and other small insects and animals that they find on or under the water. Usually they up-ends and stretch their heads into the water to reach their food. Dabblers usually have shiny colored patches on their wings. The domestic ducks are dabblers too. They are descendents of the Mallards. Dabbling ducks take off from the water in quick jumps. Examples of dabbling ducks are the mallards, cinnamon teals, shovellers, green and blue-winged teals, pintails, black ducks, baldpates and gadwalls. For ducks with long necks, they dive their head down into the shallow water and pick up their food.

Birds beaks are designed for what they eat and where they live.
hawks and other birds of prey have hooked beaks ideal for ripping and tearing prey, humming birds have long beaks for getting at insects and nectar.
Ducks have webbed feet for efficient swimming, waterproof feathers to stay dry, a streamlined body shape for speed in water, and a bill designed for filtering food from water. These adaptations help them thrive in their aquatic habitats.
