Rock Pigeon

Among the world's most successful birds, rock pigeons are native to sea cliffs and caves of Europe, North Africa, and South Asia but have been domesticated for thousands of years and introduced globally to every urban center on Earth. Their exceptional homing ability — navigating thousands of kilometers using magnetic fields, sun position, and landmarks — has made them vital military messengers and racing sport birds. Today, feral populations inhabit every major city worldwide.
