Aves is the class of warm-blooded animals that includes birds. Their feathers, beaks, and capacity for flight are what define them. While some species are not migratory, others can travel great distances. As pollinators, seed dispersers, and insect and small animal predators, they are crucial to their ecology. Many bird species have intricate social structures, and some, like ravens and parrots, are quite clever. Each of the more than 10,000 species of birds that are known to exist has distinctive characteristics, habits, and adaptations. From the highest mountains to the lowest valleys, and from the Arctic to the Antarctic, birds can be found worldwide.
