Range
Oriental Region : islands South of Japan to Philippines.Otus elegans is found on the Nansei Shoto islands and Minami-daito-jima island, southern Japan, on Lanyu Island, off south-east Taiwan (China), and on the Batanes and Babuyan islands off northern Luzon, Philippines.
Habitat
It occurs in subtropical evergreen forest, and locally in or near to villages, from sea-level to 550 m or higher.
Reproduction
Eggs are laid in March-July. Nest in tree hole or Woodpecker cavity. Clutch size is 2-3 eggs which are incubated for about 30 days. YOung fledge after a month. Clutches of 5 eggs have been observed.

Conservation
This species occurs on a number of small islands and has a moderately small global range which is under pressure from habitat conversion. Therefore the species is considered Near Threatened.
It is common wherever suitable habitat remains on the Nansei Shoto, and is presumed to have quite a large population there. The population that persisted on Kita-daito is apparently extinct but 245 territorial males were estimated on adjacent Minami-daito during the 2005 breeding season. It has a population estimated at c.1000 birds on Lanyu Island, and it has been described as fairly common on the Batanes and Babuyan islands. However, its range must have been much reduced and fragmented in the Philippines by deforestation, although its population it thought to be stable on Lanyu Island and its prospects for survival there are good so long as suitable habitat is protected. It is presumably also relatively secure on the Nansei Shoto, but its extirpation from Kita-daito highlights it vulnerability to extensive forest clearance (the island is almost entirely under cultivation now).
