The New Britain boobook (Ninox odiosa), also known as the spangled boobook, russet boobook, New Britain hawk-owl or russet hawk-owl, is a small owl that is endemic to New Britain, the largest island in the Bismarck Archipelago in Papua New Guinea.
The New Britain boobook is a small owl that grows to a length of about 22 cm (9 in). It has finely spotted chocolate-brown plumage, golden eyes and white eyebrows. Its facial disk is brown while the upper breast is marked with a wide brown band with buff or white barrings. The underparts are densely spotted brown. [3]
Its call is a series of rapidly repeated "whoo"s, starting at a low pitch which rises and becomes faster and louder. [3]
This species is found in the lowlands and hills of the New Britain and New Ireland endemic bird areas at elevations of up to 1,200 m (3,940 ft) asl. It is fairly common in its small range and is nocturnal. It roosts during the day alone or in pairs in the middle to upper parts of the forest canopy. It feeds mainly on insects and small mammals.
Formerly classified as being a "Species of Least Concern" by the IUCN, [1] the New Britain boobook was later suspected to be rarer than had previously been assumed because its rainforest habitat was being degraded by logging and forest clearance for conversion to oil palm plantations. Following the re-evaluation of its population size, this assumption was found to be correct and its numbers are now thought to be within the range of 10,000 to 20,000 individuals. Its total range is less than 30,000 km2 (11,580 sq mi) so its category was subsequently changed to "Vulnerable" status in 2008. [3]
The morepork, better known as the morepork owl, and also known by numerous other onomatopoeic names, is a smallish, brown owl species found in New Zealand, and to the northwest, on Norfolk Island, an Australian territory. It was also, formerly, found on Lord Howe Island. Three subspecies of the morepork are recognised, one of which is extinct and another that exists only as a hybrid population.
Ninox is a genus of true owls comprising 36 species found in Asia and Australasia. Many species are known as hawk-owls or boobooks, but the northern hawk-owl is not a member of this genus.
The Papuan hawk owl, sometimes also Papuan boobook is a medium-sized, sleek owl with a proportionately small head, long tail, and short, rounded wings. Its white facial disk is small and indistinct, with black streaks, and white eyebrows. It has buff-colored upperparts and barred black and brown underparts. Its eyes are bright yellow, and it has a gray to black bill. The male is larger than the female, which is unusual among owls.
The WestSolomons owl, also referred to as the West Solomons boobook, is a small to medium-sized owl, measuring 23–31 cm (9.1–12.2 in) in length. Its upperparts are rusty brown, sometimes spotted or barred with white, its chest is buffy white, sometimes spotted or barred with brown, and its creamy belly is unmarked. It has a grayish-brown facial disc, edged by narrow white eyebrows and a band of white across the throat.
The New Ireland boobook or New Ireland hawk owl also known as the Bismarck boobook, Bismarck hawk owl or barred boobook, is a small to medium-sized owl measuring 25 to 30 cm in length. It is a dark rufous-brown above, with barred scapular feathers and variable amounts of spotting or barring on the wings and tail. Its underparts are whitish, with an unmarked pale throat, a dark barred upper breast and barring on the remainder of the underparts. Its face is dark brown, its eyes are brown or yellow, and its bill and legs are yellow. It is short-tailed and has heavy tarsi.
The speckled boobook or speckled hawk owl, also called the Oriental hawk-owl, is a small owl at 17–20 cm (6.7–7.9 in). It is a reddish-brown hawk-owl with a white-spotted head, back and wings, a white throat patch, black facial disk, dark brown eyes and white eyebrows.
The Manus boobook, Manus hawk owl, Admiralty hawk owl or Admiralty Islands hawk owl is a small owl. It has an unmarked brown facial disk, rufous crown and back, barred white flight feathers and tail, and whitish underparts with rufous streaking. Its call is repeated growling, like that of a frog.
The cinnabar boobook, also known as the cinnabar hawk-owl, is a hawk-owl endemic to the island of Sulawesi, Indonesia. It was described as a new species to science by American ornithologist Pamela C. Rasmussen in 1999 based on a single specimen collected by Frank Rozendaal from Bogani Nani Wartabone National Park on Minahassa Peninsula, northern Sulawesi, in 1985. Subsequently, it has also been observed in Lore Lindu National Park in central Sulawesi, greatly expanding the known habitat range.
The Christmas boobook, also known as the Christmas hawk owl, Christmas Island boobook or Christmas Island hawk owl, is a species of owl in the family Strigidae.
The least boobook, also known as the little Sumba hawk-owl or little Sumba boobook, is a species of owl in the family Strigidae. It is endemic to the Indonesian island of Sumba. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
The northern boobook belongs to the family Strigidae and is a raptorial owl endemic to eastern and southern countries of Asia. The species was considered, until recently, a conspecific of Ninox scutulata or brown boobook, a species of similar distribution encompassing 11 subspecies. The species currently includes two subspecies, the migrant Ninox japonica japonica and the non-migrant Ninox japonica totogo. Despite being considered as the most common breeding owl in Japan, little research has been conducted on the species and subspecies and the taxonomic classification of N. j. totogo and N. j. japonica has been a subject of debate. There are no indications of significant decline in northern boobook populations and therefore its conservation status has been classified as least concern by the IUCN Red List.
The chocolate boobook is a bird species in the true owl family, Strigidae. It was formerly considered to be a subspecies of the brown boobook. It was formerly thought to be endemic to the Philippines until it was heard and recorded Karakelang in Indonesia in 1997 but there have been no subsequent records outside the Philippines since.
