The Collared imperial pigeon (Ducula mullerii), is a species of 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.
The binomial commemorates the German naturalist Salomon Müller.
Lowland rainforest, swamp forest and mangroves.
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).
