Which bird is commonly used as a messenger in history?

The story behind the answer

Pigeon is correct because domesticated homing pigeons can reliably return to their home loft over long distances, making them perfect for carrying written messages in tiny canisters. Their exceptional navigation—using a mix of Earth’s magnetic field, the sun’s position, and olfactory cues—allowed rapid, dependable communication long before radios.

Pigeon post was used in ancient Persia and Rome, by Genghis Khan’s empire, and even by news services like early Reuters. In World Wars I and II, hero pigeons such as Cher Ami and G.I. Joe saved lives by delivering critical messages and were awarded medals. Memory tip: think “pigeon post” and “homing” = “coming home.” (Doves symbolize peace, but it’s the homing pigeon that actually delivered the mail.)
