Duck Hearing
Ducks do have ears! Like many animals with fur or feathers, duck ears are not located on the sides of their heads.
Their external openings are simply holes covered in feathers, located just behind and slightly below their eyes.
Ducks use sound for almost everything. Their hearing sense is essential for communication, finding food, navigating in flight, finding mates, avoiding predators, detecting danger, and maintaining group cohesion while swimming or flying.
