How Birds Are Adapted for Flight: Key Features Explained

Discover how birds are uniquely adapted for flight with features like hollow bones, feathers, and a powerful respiratory system.

19 views

Birds have multiple adaptations for flight. Firstly, they have hollow bones that reduce weight without sacrificing strength. Their feathers provide necessary lift and insulation. The musculature, particularly the powerful pectoralis muscles attached to the keeled sternum, enables dynamic wing flapping. Furthermore, their efficient respiratory system allows maximum oxygen intake, essential for sustaining flight. Finally, their streamlined bodies minimize air resistance, making flight more efficient.
