About These Birds
Rodrigues Solitaire
Extinct flightless pigeon of Rodrigues Island, 70–90 cm and up to 28 kg. Sexually dimorphic; males bore bony wing knobs used in combat. Fed on fruits and seeds on the forest floor. Extinct by ~1730–1760 CE following human settlement and introduced pigs, rats, and cats. Closely related to the Dodo and Nicobar Pigeon.
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.
