Bird
From RationalWiki
Birds are a warm blooded class of vertebrate animals, with beaks, wings and feathers, known for flying through the air and also being delicious.
Like mammals, another warm-blooded group, birds evolved from reptiles, most likely small raptors, diverging during the Jurassic period. Birds are bipeds, walking on two legs, and are descended from theropods, a bipedal group of dinosaurs, the front limbs having gradually evolved into wings. Archaeopteryx was the earliest known bird.
All birds have wings, and most use them for flight, though there are many flightless species, including penguins, which use their wings for swimming instead. Other flightless birds such as the emu and the kiwi have no use for wings at all, but still have them, no matter how small and stubby.
It should be known that the bird => the word.
