Why do ducks have broad, flat bills?

AnimalsBirds

Quick Answer

Flat bills help ducks sift food from water and mud efficiently. The bill edges often have comb-like structures that act as filters.

The Full Story

Ducks feed using bills that are well suited to filtering and sorting small foods from water or wet sediment. Many species have lamellae, comb-like structures along the bill edges, which help trap seeds, invertebrates, and plant matter while water is expelled. A broad bill also makes it easier to dabble at the surface or strain mud for food. Different duck species have slightly different bill shapes depending on diet. Their bills are a clear example of form following feeding function.
