False — Birds

The story behind the answer

False. Bats aren’t birds—they’re mammals (order Chiroptera). Mammals have hair, external ears, and give live birth; mothers nurse their young with milk. A bat’s wing is a skin membrane stretched over elongated fingers—essentially a flying hand. Birds (class Aves) are defined by feathers, beaks, and hard-shelled eggs; their wings are feathered forelimbs.

Interesting context: flight evolved independently in bats and birds (convergent evolution). Bats are the only mammals capable of sustained powered flight and many use echolocation, while birds rely mainly on vision and feathers for lift, insulation, and display. Memory tip: Feathers = bird; Fur + Milk = mammal.
