Cute Birds Sing a Song

Birds are a diverse group of warm-blooded animals with feathers, beaks, wings, and the ability to lay eggs. They are found all over the world, from the Arctic to the Antarctic, and come in a wide range of sizes, shapes, and colors. Birds are known for their ability to fly, although not all species are capable of sustained flight. Flightless birds, such as ostriches and penguins, have evolved to move efficiently on land or in water.
