Physical description Click here for a physical description Torresian Imperial-Pigeons are big pigeons. Their plumage is almost all-white, except the tips of the wings, a terminal band on the tail and barring on the undertail (which are all black). The eyes are black, the bill is yellowish-green and the legs and feet are grey. Twitcher's tip Compared to White-headed Pigeons, the Torresian Imperial-Pigeon does not have an eye ring and has much lighter-coloured wings and tail.

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed based on sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Torresian Imperial-Pigeon is available HERE . The range of the Torresian Imperial-Pigeons extends from northern and eastern coastal Australia, via the Torres Strait, to New Guinea, eastern Indonesia and the Solomon Islands. In Australia Torresian Imperial-Pigeons are found on several islands along the Torres Strait and along the tropical North coast and the tropical and subtropical East coast of the continent. They migrate from the North to an area from about Derby, WA, in the West to Yeppoon, QLD (the tropic of Capricorn), in the East. They breed primarily along the East coast of Cape York peninsula, but their range is expanding, with birds now found as far to the South as Sydney, NSW. Torresian Imperial-Pigeons are found in a variety of habitats, e.g. coastal rainforest, mangroves and commercial plantations.
