About These Birds
Choiseul Pigeon
Extinct large ground pigeon, estimated 30–35 cm, with a blue-grey body, bluish crest, red bill, and orange-red legs. Known only from six specimens collected on Choiseul Island in the Solomon Islands in 1904. Never reliably recorded again; extinct by the early 20th century, likely due to introduced predators and intensive hunting.
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.
