About These Birds
Liverpool Pigeon
Extinct island pigeon, known from a single specimen in the World Museum Liverpool and a painting. Believed to have inhabited Pacific islands, possibly the Marquesas or Society Islands, based on morphology. Dark grey with white spots. Extinct; likely died out in the 18th or 19th century from hunting and introduced predators.
Rock Pigeon
The rock pigeon is the ancestor of all domestic pigeon breeds and one of the most abundant birds in cities worldwide. Pigeons have served humans as messengers, food, and subjects for scientific research — their homing ability and vision have been studied extensively. Darwin's study of pigeon breeding contributed to his theory of evolution.
