What is the tip of a duck's bill called?

The tip of a duck's bill is referred to as "the bean." This term specifically describes the rounded, sensitive part located at the end of the bill, which is important for foraging. The bean contains a high concentration of nerve endings, enabling ducks to detect food and navigate their environment through touch. This feature is particularly useful as ducks often feed in murky waters where visibility is low. Understanding the structure and terminology of a duck's anatomy helps in recognizing their feeding habits and ecological adaptations.
