The Chatham pigeon (Hemiphaga chathamensis), also known as the Chatham Island pigeon or parea (from Moriori), is a species of pigeon endemic to the Chatham Islands in New Zealand. Growing to 800g in weight and 55 cm in length, the Chatham pigeon is a relative of the kererū or New Zealand pigeon (Hemiphaga novaeseelandiae). Traditionally considered a subspecies of the kererū, it was proposed in 2001 to be distinct enough to be raised to full species status.
