Barn-owls are one of the two families of owls, the other being the true owls or typical owls, Strigidae. They are medium to large owls with large heads and characteristic heart-shaped faces. They have long, strong legs with powerful talons. They also differ from the Strigidae in structural details relating in particular to the sternum and feet.
The Admiralty Islands are an archipelago group of 40 islands in the Bismarck Archipelago, to the north of New Guinea in the South Pacific Ocean. These are also sometimes called the Manus Islands, after the largest island.
The barn owl is the most widely distributed species of owl in the world and one of the most widespread of all species of birds, living almost everywhere except for polar and desert regions, Asia north of the Himalayas, some Indonesian islands and some Pacific Islands. It is also known as the common barn owl, to distinguish it from the other species in its family, Tytonidae, which forms one of the two main lineages of living owls, the other being the typical owls.
The red owl is an owl in the barn owl family Tytonidae. It is also known as the Madagascar red owl, Madagascar grass-owl, Soumagne's owl or lesser grass-owl. It is a rare resident of Madagascar that was virtually unknown from its discovery in 1876 to its rediscovery by researchers from the World Wide Fund for Nature in 1993. It is currently listed as vulnerable because of habitat loss, but recent studies have determined it may have a wider range than first believed, though further research in distribution and ecology is required. It has possibly been overlooked because of its close resemblance to the closely related barn owl.
The greater sooty owl is a medium to large owl found in south-eastern Australia, Montane rainforests of New Guinea and have been seen on Flinders Island in the Bass Strait. The lesser sooty owl, is sometimes considered to be conspecific with this species, in which case they are then together referred to as sooty owls. It is substantially smaller and occurs in the wet tropics region of North Queensland, Australia.
The Australian masked owl is a barn owl of Southern New Guinea and the non-desert areas of Australia.
The New Britain boobook, 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 lesser sooty owl is a medium-sized barn owl endemic to the wet tropics region of Australia. Once considered a subspecies of the greater sooty owl, it is distinguished by its dark plumage, heavier spotting, and higher-pitched call. The lesser sooty owl has a limited range within northeastern Australia and primarily lives in dark, sheltered areas of the rainforest.
The Minahasa masked owl, also known as the Minahasa barn owl, Sulawesi owl or Sulawesi golden owl, is a barn owl endemic to the island of Sulawesi, Indonesia. The name is derived from the Minahassa Peninsula, where it was first described as a breeding bird; however, it is also known to live in north-central Sulawesi.
The New Britain thicketbird or Bismarck thicketbird is a bird species. It used to be placed in the "Old World warbler" family Sylviidae, but it does not seem to be a close relative of the typical warblers; probably it belongs in the grass warbler family Locustellidae. It is found only in the rarely visited highlands of the island of New Britain in Papua New Guinea.
The African grass owl is a species of owl in the barn owl family, Tytonidae.
The ashy-faced owl is a species of bird in the barn-owl family Tytonidae. It is found on the Caribbean island of Hispaniola, on Dominica, and on several other islands of the Lesser Antilles.
The eastern grass owl, also known as Chinese grass owl or Australasian grass owl, is a species of owl in the family Tytonidae. They feed predominantly on small rodents.
The Sulawesi masked owl is a species of owl in the family Tytonidae. It is endemic to the Indonesian islands of Sulawesi, Sangihe and Peleng. It is listed by the IUCN as being of least concern.
The Bismarck masked flying fox is a species of flying fox in the family Pteropodidae found in Papua New Guinea and named after the Bismarck Archipelago. It was once considered a subspecies of Pteropus temminckii before being reassessed in 2001. This species has two subspecies, P. c. capistratus and P. c. ennisae. The IUCN classified it as Near Threatened in 2009, noting that the rate of decline is almost high enough to reclassify the species as Vulnerable.
The Tasmanian masked owl is a bird in the barn owl family Tytonidae that is endemic to the island state of Tasmania, Australia. It is the largest subspecies of the Australian masked owl, the largest Tyto owl in the world, and is sometimes considered a full species. The subspecific name castanops, meaning "chestnut-faced", comes from the colouring of the facial disc. It was first described by John Gould, who wrote about it in his Handbook to the Birds of Australia as:
"…a species distinguished from all the other members of its genus by its great size and powerful form. Probably few of the Raptorial birds, with the exception of the Eagles, are more formidable or more sanguinary in disposition."
"Forests of large but thinly scattered trees, skirting plains and open districts, constitute its natural habitat. Strictly nocturnal in its habits, as night approaches it sallies forth from the hollows of the large gum-trees, and flaps slowly and noiselessly over the plains and swamps in search of its prey, which consists of rats and small quadrupeds generally."
The Andaman masked owl is a barn owl endemic to the southern Andaman Islands archipelago of India, in the Bay of Bengal, Indian Ocean. Regarded by some authors as a subspecies of the common barn owl, it is recognized by others as a species in its own right.
The northern masked owl is a large forest owl in the family Tytonidae. The northern kimberli subspecies was identified as a novel race of the Australian masked owl by the Australian ornithologist Gregory Macalister Mathews in his 1912 reference list of Australian birds. The northern masked owl occurs in forest and woodland habitats in northern Australia, ranging from the northern Kimberley region to the northern mainland area of the Northern Territory and the western Gulf of Carpentaria. While the Australian masked owl is recognized as the largest species in the family Tytonidae, the northern masked owl is one of the smallest of the Australian masked owl subspecies.
