Study Notes
Bird Skeleton
- The primary function of birds' light skeletal system is to reduce weight and enhance flight efficiency.
- The beak in birds serves as a multifunctional tool for foraging, tearing, and manipulating food, in addition to preening and social behaviors.
Adaptations for Flight
- A key adaptation of the bird skeleton for flight is the presence of hollow bones, which reduces weight and enhances flight efficiency.
- Respiratory air sacs often form within the bird's skeleton, specifically within the hollow bones, to provide additional oxygen storage and facilitate more efficient respiration.
Diving Birds
- The bones of diving birds are distinguished from those of non-diving species by their increased density, which helps to counteract the buoyancy of water and facilitate diving.
