Aves, commonly known as birds, are warm-blooded vertebrates characterized by feathers, beaks, and the laying of hard-shelled eggs. They belong to the class Aves and are found in diverse habitats around the world, from forests to deserts and oceans. Birds play crucial roles in ecosystems, including pollination, seed dispersal, and pest control. With over 10,000 species, Aves exhibit a wide range of sizes, colors, and behaviors. Some, like the Bald Eagle, are known for their impressive hunting skills, while others, like the Hummingbird, are celebrated for their ability to hover in mid-air. Birds are also known for their complex vocalizations and social structures.
