Question: Describe three skeletal adaptations that allow for flight in birds?
One of the skeletal adaptations that allow for flight in birds is the fusion of some bones, such as the pelvic girdle and the thoracic vertebrae, which provides rigidity and stability to the body during flight. Another adaptation is the reduction of bone mass, which lowers the weight of the bird and makes it easier to lift off. Some bones are hollow and filled with air sacs that connect to the respiratory system, which also reduces weight and increases oxygen supply. A third adaptation is the modification of the forelimbs into wings, which have a large surface area and a curved shape that creates lift and thrust when flapped.
