[4] Five subspecies are recognized: D. o. monacha in Palau and Yap, D. o. teraokai on Chuuk, D. o. townsendi on Pohnpei, D. o. oceanica on Kosrae, and D. o. ratakensis in the Marshall Islands.

[5] The Micronesian imperial pigeon is about 36 cm (14 in) long and weighs 340–406 g (12.0–14.3 oz).

[2] This species of bird makes many different types of calls, which can sound like barking, cooing, or moaning.

The Micronesian imperial pigeon is found in the Marshall Islands, Yap, Chuuk, Pohnpei and Kosrae of Micronesia, Nauru, Kiribati and Palau.

[2] The species also occurred once in the Mariana Islands, where Holocene subfossil remains are found.

Its calls include a deep-throated bark grrow-row-row-ow, a moan, and mellow coos.

[1] A 2005 survey in Palau found that, on Babeldaob and the Rock Islands, the species had declined but was still common.

[1] The Micronesian imperial pigeon is hunted, possibly causing the population decline on Palau and Nauru.
