The Collared Imperial-pigeon, (Ducula mullerii), is a large (40 cm in length, 600 g in weight) pigeon with grey upperparts and largely grey-pink underparts, distinguished by a striking and diagnostic complete black collar against an otherwise white throat.

[edit] Distribution

Northern and southern New Guinea and the Aru Islands. It has been recorded from Boigu and Saibai Islands, Australian territory in northern Torres Strait.

[edit] Habitat

Lowland rainforest, swamp forest and mangroves.

[edit] Diet

Fruit from forest trees and insects. In the Port Moresby area, the main food during June/July was reported to be fruit of Tristiropsis canarioides which made up nearly half the diet. Some 30% of food volume were Ylang-ylang (Cananga odorata) fruit, the remainder being various Arecaceae (palm) fruits. Fruits eaten had a volume between 2 and 5 cm³, which would mean a diameter of about 1,5–2 cm in spherical fruit. Food is swallowed whole.(Frith et al. 1976)

[edit] Nesting

Lays single egg on flimsy platform nest in forest tree adjoining wetland.

[edit] Taxonomy

The binomial commemorates the German naturalist Salomon Müller.
