Birds name and sound name in english | Kids school #animalnames #birds #birdsnameenglish Birds are warm-blooded vertebrates, the only animals with feathers, characterized by wings (though not all fly), beaks, two legs, and egg-laying, featuring light skeletons and high metabolisms, with species varying greatly in size, color, diet (insects, seeds, nectar, fish), and habitats worldwide, from tiny hummingbirds to large ostriches. Their unique systems (respiratory, digestive) and lightweight, often hollow bones are adaptations for flight, though some evolved for swimming (penguins) or running (ostriches).
