Species
Birds are warm-blooded, egg-laying vertebrates with feathers, wings, and beaks. Most birds can fly, though some are flightless. They are found worldwide in diverse habitats, from forests to deserts. Birds play important roles in ecosystems as pollinators, seed dispersers, and predators of insects. They communicate through songs and calls, and many species migrate seasonally. With over 10,000 species, birds display a wide variety of colors, sizes, and behaviors.
