4 mars 2024 · Birds have hollow bones to make them light for flying. This helps them use less energy and makes it easier for them to lift off, fly efficiently, and maneuver in the air. Hollow bones are strong and support birds in flight without adding extra weight. These special bones also help birds breathe better during flight by improving ...
Learn how birds' hollow bones reduce their weight, increase their flying abilities, and provide structural support, sound production, and mineral storage. Discover how different types of birds have adapted their bone structure for their specific needs, and how they maintain their bone health with calcium-rich diets and efficient respiration.
