Beak Structure and Function

• A hummingbird's beak is not hollow, and it does not suck nectar as if through a straw. Instead, its beak contains a long tongue with a brush-like tip that allows it to lap nectar. A hummingbird beak has an upper and lower portion that can be opened very slightly and with great control. Additionally, researchers at the University of Connecticut found that hummingbird beaks can bend up to 20 degrees, enabling them to more easily catch flies and small insects.
