A Roller pigeon is a domesticated breed or variety of pigeon that has been selected for its ability to tumble or roll in the air. The Oriental Roller (Columba livia) is a breed of fancy pigeon developed over many years of selective breeding. The key hallmark of the Oriental Roller is its flying style. They show a variety of different figures in the air, which are single somersaults, double somersaults, rolling (a number of uncountable somersaults), rotation with open wings, nose dives, sudden change of direction during flight and very rarely axial turns. Some breeds fly up to 1000 m high, others stay in the air for several hours. Oriental Rollers, along with other varieties of domesticated pigeons are all descendants from the rock pigeon.
