False — Birds

The story behind the answer

Correct answer is false because birds are defined by feathers; no other living animals have them. Birds also have beaks, lay hard-shelled eggs, and are warm-blooded. Many fly, but flight isn’t required (think ostriches and penguins), so wings alone don’t make something a bird. If the subject has fur and teeth (a bat), six legs and an exoskeleton (an insect), or is a machine like a plane, it’s not a bird.

Fun context: Birds are living dinosaurs; feathers first evolved for insulation and display long before powered flight. To identify birds quickly, use: "Feathers = bird; wings alone don’t." Look for a beak, feathered body, and scaly feet. If those aren’t present, you’re not looking at a bird.
