False — Birds

The story behind the answer

False is correct because only birds have feathers—no other living animal does. Birds are warm‑blooded vertebrates with beaks (no teeth), two wings, two legs, a keeled breastbone for flight muscles (in most species), and they lay hard‑shelled eggs. If an animal shows fur or hair, external ears, or toothy jaws, it’s a mammal; six legs and antennae indicate an insect; scaly skin without feathers points to a reptile.

Remember it this way: feathers = bird. Bats may fly, but their wings are skin stretched over long finger bones and they have teeth and ears—classic mammal traits. Some birds don’t fly (like ostriches), but they still have feathers. Spot the feathers and beak first, and you’ll quickly separate birds from look‑alikes.
