What is the real use of carrier pigeons?
A "carrier pigeon" is a homing pigeon (specifically a domesticated Rock Pigeon, Columba livia domestica) that can be used to carry messages. Using pigeons to carry messages is generally called "pigeon post".These birds have an innate homing ability. When released at a distant site, the pigeons will instinctively fly back to their home nest, which might be hundreds of kilometers away.
