Cinnamon-bellied Imperial-Pigeon

The cinnamon-bellied imperial pigeon (Ducula basilica) is a large, arboreal fruit pigeon in the family Columbidae, endemic to the Moluccas (Maluku Islands) of eastern Indonesia, including Halmahera, Bacan, Obi, Ternate, and adjacent smaller islands. It inhabits primary and mature secondary lowland and hill forest, where it feeds on fruits, figs, and berries in the forest canopy. The plumage is largely dark metallic green above with a distinctive cinnamon-rufous underside that differentiates it from related imperial pigeons. Large fruit pigeons of the genus Ducula are important seed dispersers in island forest ecosystems, capable of swallowing large fruits whole and dispersing seeds far from parent trees. The species is classified as Least Concern by the IUCN, with populations considered stable in the Moluccas. However, all large fruit pigeons are susceptible to hunting pressure and habitat loss, and monitoring is needed given ongoing forest conversion in eastern Indonesia. The Moluccas harbor exceptional bird diversity due to their position between Asian and Australasian biotas. This species is absent from Europe entirely; Norwegian database records are incorrect geographic artifacts. Conservation of intact lowland forest in the Moluccas is important for this and many co-occurring endemic species.
