Heya....Empress Here...
• They have a flexible and light skeletal system made up of pneumatic bones.
• They have different layers of feathers in their body performing specific functions like helping them fly and insulation.
• They are blessed with streamlined body for fast, rapid and smooth movements and are also given fast reflexes.
• Forelimbs are modified into wings, allowing them fly, and hind limbs are used for swimming, walking etc.
