Birds have a lightweight skeletal system to facilitate flight. Their bones are hollow, and many of them are fused to provide strength and rigidity. Flight muscles, attached to the breastbone or sternum, power the flapping motion of wings. Some bird species, such as penguins, have adapted to an aquatic lifestyle and have modified wings for swimming.The beak or bill of a bird varies in shape and size, reflecting the species' feeding habits. It is a specialized structure that enables birds to grasp, manipulate, and consume a wide range of food, including insects, fruits, seeds, nectar, fish, and small mammals. Birds lack teeth, and the beak serves as their primary tool for catching and processing food
