The animal known for its ability to fly is the bird. Birds are characterized by their feathers, wings, and lightweight bodies, allowing them to soar through the skies. Various species of birds, like eagles, sparrows, and hummingbirds, have adapted unique flight patterns and behaviors. Birds use flight for numerous reasons, including foraging for food, escaping predators, and seasonal migration. While most birds can fly, some, such as ostriches and penguins, have adapted to life on the ground or in water instead. Overall, the ability to fly has played a crucial role in the evolution and survival of birds.
