Which feature indicates the diet of birds?

• A. Feet show the diet
• B. Wings show the diet
• C. Beaks show the diet
• D. Habitat show the diet

Answer: (C)

Beaks reveal what a bird eats because their shape and structure are directly shaped by feeding needs. The beak acts as the main tool for capturing and processing food, so its form reflects the kind of prey or forage a bird specializes in. For example, seed-eating birds have strong, stout beaks to crack tough shells; insectivores often have pointed or slender beaks to pick prey from tiny spaces; fish-eaters tend to have longer, sharper, or hooked beaks to grab slippery prey; nectar feeders show curved, delicate beaks to sip from flowers. Feet, wings, or habitat influence how a bird moves, hunts, or lives, but they don’t as clearly reveal the specific diet. Therefore, the beak is the best indicator of a bird’s diet.
