Birds have a backbone, making them vertebrates. Their vertebrae are specialized for flight, providing strength and flexibility while also protecting the spinal cord.
2. Internal Skeleton
Birds possess an internal skeleton composed of bones. This bony structure provides support, protection, and leverage for movement and locomotion.
3. Specialized Adaptations for Flight
Birds have several adaptations that enable them to fly, including:
- Wings: Birds have wings that are modified forelimbs. These wings allow them to generate lift and propel themselves through the air.
- Feathers: Birds have feathers that provide aerodynamic surfaces for flying and aid in insulation and temperature regulation.
- Hollow Bones: Many bird species have hollow bones, making their skeletons lightweight while maintaining structural integrity.
