General Info

Species Status

Like all species of Japanese wood pigeons, the Ryukyu wood pigeon was very susceptible to habitat destruction. It required substantial areas of undisturbed subtropical forest to thrive. Iejima, for example, was largely deforested for settlement and agriculture even before scientific exploration began, which explains the absence of records from this island. The species was last recorded on Okinawa in 1904, probably succumbing to hunting. In the Daitō group, it disappeared after 1936 due to these small islands being completely deforested by settlement and construction activity prior to World War II. It was presumed to continue to exist on the outlying islands in the Okinawa group, but has never been found again. Theoretically, there is sufficient habitat remaining in the mountains of Okinawa. Still, the military activity during World War II and hunting by the Japanese garrison would probably have yielded sightings, if birds still had existed there. More puzzling is the absence of any records from Tokashikijima in the Kerama Retto, which, despite being small, has still mostly intact forest cover even today; Zamamijima, where the species is known to have occurred is smaller still and situated farther away from the Okinawan mainland.
