Question

characteristics of bird​

Answer 1

Birds are warm-blooded, egg-laying animals that have vertebrae, or a backbone. They are different from mammals because they lay hard-shelled eggs and have feathers. A bird has four limbs—two that are wings—along with a beak and no teeth

CHARACTERISTICS OF BIRDS :

• Birds are warm-blooded. They have feathers, wings and lay eggs. Birds can fly with the help of their hollow bone. Chicken is the most common species of bird all over the world.
• lightweight, smooth feathers – this reduces the forces of weight and drag and make them able to fly.
• a beak, instead of heavy, bony jaws and teeth – this reduces the force of weight in order to make them fly.
• an enlarged breastbone called a sternum for flight muscle attachment – this helps with the force of thrust providing them capabilities to fly.
• Birds were able to become flying machines largely through the evolutionary gifts of feathers, powerful wings, hollow bones, warm blood, a remarkable respiratory system, and a large, strong heart.ama
• Birds, like this Bald Eagle, don't have teeth, but they do have other adaptations to help them break down food. Photo by Joe via Birdshare. Birds do not have teeth, although they may have ridges on their bills that help them grip food.
