Birds
Birds are warm-blooded vertebrates belonging to the animal kingdom, specifically the class Aves. Characterized by feathers, beaks, and the ability to lay hard-shelled eggs, birds are found in diverse habitats worldwide. They possess lightweight skeletons, enabling flight in most species, though some are flightless. Birds play vital ecological roles as pollinators, seed dispersers, and predators, and they exhibit a wide range of behaviors, vocalizations, and nesting habits.
