The Torresian imperial pigeon (Ducula spilorrhoa), also known as the nutmeg pigeon, white nutmeg pigeon, Australian pied imperial pigeon or Torres Strait pigeon, is a relatively large, pied species of pigeon. It is found in forest, woodland, savanna, mangrove and scrub in Australia (north-east Western Australia, north Northern Territory and north Queensland, including the Torres Strait Islands), New Guinea, Aru Islands, islands in the Geelvink Bay, D'Entrecasteaux Islands and Louisiade Archipelago. It has also been recorded as a vagrant in New South Wales, Australia. As far as known, most populations are resident or only take part in minor local movements, but the population in Queensland leaves for New Guinea in February–April and returns in July–August.
The Torresian imperial pigeon is a large plump pigeon, 38-44 centimetres (15-17.5 inches) in length, and with a 45 cm (18 in) wingspan. It is entirely white or pale cream, apart from the black flight feathers (remiges), part of the tail (rectrices) and spots on the undertail coverts. The head can be brown, soiled by eating fruit.
The flight of the pigeon is fast and direct, with the regular beats and an occasional sharp flick of the wings which are characteristic of pigeons in general.
The male displays by flying up steeply, pausing, tipping forward and then gliding downwards. The female builds an untidy stick nest in a tree, usually a coconut palm and lays a single white egg, which hatches within 26 to 28 days. The squab fledges after another three weeks. In Australia they breed between August and January in mangroves, vines, palm fronds on off-shore islands, such as the Brook Islands. In north-east Queensland, they migrate daily as flocks from the islands to the mainland rainforests to eat fruit, returning to the islands at dusk.
