Birds are a group of warm-blooded vertebrates that belong to the class Aves. They are characterized by their feathers, beaks, and the ability to fly. Some species are capable of long-distance migration, while others are non-migratory. They play an important role in their ecosystem, serving as pollinators, seed dispersers, and predators of insects and small animals. Some birds, such as parrots and ravens, are highly intelligent, and many species have complex social structures. There are over 10,000 known species of birds, each with its own unique features, behaviors, and adaptations. Birds can be found all over the world, from the Arctic to the Antarctic, and from the highest mountains to the lowest valleys.
