If all you have learned of owls is that they are nocturnal and the only species of owl you visualize is the common barn owl, then you'd love to learn about the greater sooty owl. This owl (Tyto tenebricosa) is a medium to large owl found in south-eastern parts of the Oceania countries (Australia and New Guinea).
The greater sooty owl is sedentary and territorial throughout the year. Their call is a piercing shriek that can last up to two seconds and resembles the sound of a falling bomb whistle.
Such is the beauty of nature that the male brings food to the female as gifts during the breeding season. If the female finds such advances acceptable, the birds copulate, and females lay dull white eggs.
The sooty black color, after which the greater sooty owl (Tyto tenebricosa) is named, gets darker as they age.
Their facial disk is black to dark gray, sooty black, or silver in color. They have a finely white-spotted head with scattered white spots on the wings.
The upper part of this bird is dark gray or black; in contrast, it's under part is lighter. The females appear to have a lighter color than their male counterparts.
Their legs are feathered, and they have a short tail. If you enjoy this article, check out these tawny owl facts and eastern barn owl facts.

The breeding season of the greater sooty owl (Tyto tenebricosa) is between January and June. While this range is quite wide, these owls might still breed outside the season, with records of eggs being laid in spring.

The nest of these sooty owls is in large hollow trees at heights of 32-164 ft (9.8-50 m).
The female leaves sight of her eggs only during the night once they are laid. If the nests are in caves, the female rarely leaves the eggs, even during the night.

In at least two Australian states (New South Wales and Victoria), the greater sooty is listed as vulnerable. The primary drivers of their endangerment are the loss of their habitat and climate change.
