The golden masked owl (Tyto aurantia) is a barn owl endemic to the island of New Britain, Papua New Guinea. It is also known as New Britain barn owl, New Britain masked owl, Bismarck owl and Bismarck masked owl.

Contents

As with other tropical barn owls, it is difficult to spot in the wild and therefore poorly studied. It is likely to be a lowland forest or coniferous species.

Given the paucity of reliable information, it was for some time classified as a data deficient species by the IUCN. [3] When its status could finally be evaluated properly, earlier assessments were found to be correct, and it is once again listed as a Vulnerable species in the 2008 red list. [4]

General description

Golden masked owls are characterized by their brown, light-brown, and white feathered plumages along with their arguably most distinctive feature - their heart-shaped, bright white face. There is considerable variation in the exact weight of the species, but most birds range from 0.9 to 1.7 pounds, with heights ranging from 10.6 to 12.9 inches. The golden masked owl is a largely solitary and nocturnal species. Being mostly active at night, golden masked owls have developed a keen sense of hearing which is also common in nocturnal owl species. Golden masked owls are carnivorous and most of their prey is hunted on the ground with the majority of their prey consisting of small mammals such as rodents, other birds, rabbits, and insects. [5]

Dwelling and nesting behaviour

Golden masked owl dwellings are commonly hollow trees. The size and style of dwelling best suits the golden masked owl's nesting behavior which involves laying an average of 2 to 3 eggs. With its most common predators being eagles, hawks, and larger owls, golden masked owl dwellings also serve as protection from these predators for both the eggs and the female owl while it incubates them over the course of roughly 32 days. The golden masked owl dwelling also serves to protect newly born owlets in the period of time between when they hatch and when they are able to live independently which is roughly 80 days. [5]

Habitat loss

The golden masked owl's primary habitat, as previously stated is lowland or coniferous forests on the island of New Britain which is located off the coast of Papua New Guinea. [5] Their unique habitat plays a key role in the survival of their species, and habitat loss has caused their conservation status to fall to vulnerable over time. While not explicitly endangered, being labeled as a vulnerable species is still within the broader category of being threatened. [6] Their current habitat range is roughly 63,000 square kilometers; [6] however, the status of forests and the larger ecoregion on New Britain and neighboring New Ireland have since been labeled as “critical/endangered” by the World Wide Fund for Nature (WWF). [7] This projection means that the golden masked owl is currently in danger of further habitat loss. As a result, the population of golden masked owls, currently in the range of 2500 to 9999 individuals, is trending downward. [6] Habitat loss in the case of the golden masked owls can be directly attributed to deforestation on New Britain island which is a product of large-scale infrastructure projects, agricultural expansion, and commercial logging.

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 barn owl is the most widely distributed species of owl in the world and one of the most widespread of all species of birds, being found almost everywhere except for the polar and desert regions, Asia north of the Himalayas, most of Indonesia, 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 (Strigidae).

<span class="mw-page-title-main">Red owl</span> Species of owl

The red owl is an owl in the barn owl family Tytonidae. It is also known as the Madagascar red owl, Madagascar grass-owl and Soumagne's 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. They have a finely white spotted head with scattered white spots on the wings. The females are lighter colored than the males. The females' length is 37–43 cm and weighs 750-1200 g. The smaller male has a length of 37–43 cm and weighs 500-700 g. The wing length is 30–40 cm. The large dark eyes are set in a round large facial disk. The facial disk is dark gray-silver or sooty black and has a heavy black edge. The upper part of the owl is black to dark gray and the under part is lighter. The tail is short and the legs are feathered. The feet and talons are large. Their call is a piercing shriek which can last up to two seconds.

<span class="mw-page-title-main">Tasmanian masked owl</span> Subspecies of bird

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."

<span class="mw-page-title-main">Northern masked owl</span> Subspecies of bird

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.
