About These Birds
New Zealand Pigeon
New Zealand Pigeon / Kereru (Hemiphaga novaeseelandiae), 51 cm. Large and robust; iridescent green-and-bronze upperparts, white underparts. Endemic to New Zealand and the Kermadec Islands. Inhabits native forest. Sole disperser of large-seeded native trees (e.g. karaka, miro). Frugivore. Least Concern but protected.
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.
