About These Birds
Norfolk Ground Dove
Small ground dove, 20–23 cm, with dark brown upperparts and pale buff underparts. Extinct; formerly inhabited Norfolk Island in the southwestern Pacific. Last confirmed record in the 1800s; became extinct through hunting and habitat clearance following European settlement.
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.
