Birds (class Aves) are winged, bipedal, endothermic (warm-blooded), vertebrate animals that lay eggs. There are around 10,000 living species, making them the most numerous tetrapod vertebrates.
Funny, I always thought a tetrapod was something with four legs (hence tetra), then again, it might just be a blanket term for critters. Anyone enlighten me?
