Morepork
The morepork, also known by its Māori name ruru, is a small brown owl native to New Zealand and Norfolk Island, with a former presence on Lord Howe Island. It is distinguished by its dark-brown plumage with pale spots, golden-yellow eyes, and a distinctive "more-pork" call. This generally nocturnal owl hunts insects and small vertebrates by perching and pouncing, demonstrating excellent night vision and hearing.

About Morepork
The morepork, scientifically known as Ninox novaeseelandiae and by its Māori name ruru, is a small brown owl native to New Zealand and Norfolk Island, with a historical presence on Lord Howe Island. Its common names, including boobook and mopoke, are derived from its characteristic calls. The species exhibits dark-brown plumage adorned with pale spots and possesses striking golden-yellow eyes.
Description and Behavior
Moreporks typically measure between 26 to 29 cm in length, with females being slightly larger and heavier than males. They are predominantly nocturnal hunters, utilizing their exceptional night vision and acute hearing to locate prey, which includes large insects like beetles and moths, as well as small vertebrates such as mice and lizards. Their hunting technique often involves perching and then pouncing on unsuspecting prey. While primarily active at night, they may also be seen hunting during dawn and dusk hours.
Taxonomy and Distribution
First formally described in 1788, the morepork's taxonomic classification has been subject to revision, with it previously being grouped with the Australian boobook (Ninox boobook) and the Tasmanian boobook (Ninox leucopsis). Genetic studies in recent years have led to the reclassification of the Tasmanian boobook as a distinct species. Three subspecies have been recognized: N. n. novaeseelandiae found in New Zealand, N. n. undulata on Norfolk Island, and the extinct N. n. albaria from Lord Howe Island.
Habitat and Conservation
The morepork inhabits forests in New Zealand, favoring those dominated by native trees such as Podocarpus and Nothofagus, extending up to the alpine tree line. On Norfolk Island, it resides in forests of Norfolk Island pine. The species is generally found singly, in pairs, or in small family units. The International Union for Conservation of Nature (IUCN) has assessed the morepork as a species of least concern, owing to its extensive range and a stable population, indicating no significant current threats of decline.

Where does the morepork live?
The morepork is found in New Zealand, the Australian island of Norfolk Island, and formerly Lord Howe Island. Within New Zealand, it inhabits forests from the North Island to Stewart Island.
What does the morepork eat?
The morepork's diet primarily includes large invertebrates such as beetles, moths, caterpillars, spiders, and grasshoppers. It also preys on small vertebrates like lizards, rats, and mice.
What makes the morepork's call distinctive?
The morepork is named for its most frequent vocalization, a "more-pork" call. However, researchers have identified as many as 11 distinct calls, including a high-pitched yelping, a whistling call, and a lower pitched "quork-quork" rumbling call.
What is the conservation status of the morepork?
The morepork is listed as a species of least concern by the International Union for Conservation of Nature (IUCN). This is attributed to its large geographical range and apparently stable population, with no evidence of significant decline.
