Large pigeon endemic to New Zealand with distinctive blue-green iridescent plumage, white belly, and red eye. Makes conspicuous display flights in breeding season; often seen feeding on heavily fruiting trees or fresh leaves and flower buds in spring. Widespread where food is available. Only emits soft “oo” calls, but note distinctive wingbeat sound, especially when alighting or taking off. Chatham Island Pigeon, the only similar species, is larger and confined to Chatham Islands.
