Mountain Imperial Pigeon Ducula badia, is found over a large part of southern mainland Asia, as well as the Malay Peninsula, Sumatra, Borneo and Java.
In Borneo, usually a montane bird but occasionally found in lowland coast. In montane forests, resident from about 900 metres up to 2,450 metres.
Usually seen singly in the mountains, however, large flocks numbering up to hundreds individuals have been seen in mangrove along the coast.
Individuals may also make daily flights to lowlands forest or mangroves to feed, and such flights are dependent on the fruiting cycles in the mountains and the lowlands. They are thought to return to montane forest each night to roost, and probably remain in the mountains when incubating eggs or attending young.
This Mountain Imperial Pigeon was photographed in Rafflesia Information Centre, my new photographed wild birds of Borneo.
