The Collared Imperial Pigeon, known scientifically as <em>Ducula mullerii</em>, is a large fruit-eating pigeon belonging to the genus Ducula within the family Columbidae. This species is characterised by its distinctive plumage, which typically features a pale grey or whitish head and underparts contrasting with darker upperparts, giving rise to its common name. <em>Ducula mullerii</em> is associated with lowland and foothill forest habitats, where it typically forages in the forest canopy and subcanopy for fruits and figs. The species is reported to occur in Norway according to available range data. Like other imperial pigeons of the genus Ducula, it is generally found in tropical and subtropical forest environments. Detailed biological traits including lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Imperial Pigeon is currently assessed as Least Concern on the IUCN Red List, indicating that the global population is not considered to be facing immediate threats of significant decline.
