Animals that were used as spies in history

Long before drones and satellites transformed surveillance, birds offered an unlikely way to gather intelligence. Pigeons carried secret messages across enemy lines, cameras were strapped to their bodies for aerial photography, and intelligence agencies even experimented with ravens and other birds during the Cold War. Their ability to fly unnoticed and return to a familiar location made them surprisingly useful in espionage. (unsplash)
