What adaptations do woodpeckers have for their feeding habits?

• A. Long tongues for catching insects in flight
• B. Large eyes for night vision
• C. Strong beaks for drilling into wood and specialized skulls to absorb shock
• D. Powerful wings for fast flight

Answer: (C)

Woodpeckers feed by pecking and drilling into tree trunks to reach hidden insects, so their feeding adaptations must cope with repeated impact. The strong beak acts like a durable chisel, letting them bore into tough wood. But the head itself has to survive those constant hammer blows, so woodpeckers evolved a skull with reinforced structures and shock-absorbing features that cushion the brain during repeated impacts. In addition, the long, specialized tongue supported by a wrapping hyoid bone helps them reach insects deep inside crevices after drilling, enhancing their ability to extract prey. The other ideas don’t fit their feeding method as well: they aren’t nocturnal hunters relying on night vision, and fast flight isn’t a feeding adaptation for this behavior.
