On Norfolk Island, it lives in forests of Norfolk Island pine (Araucaria heterophylla).. Researchers say one of the world's rarest owl species has a chance at survival after a breakthrough discovery on a remote Australian island. The Norfolk Island morepork owl was all-but extinct in the 1980s with only one female left.  In his 1968 book Nightwatchmen of the Bush and Plain, Australian naturalist David Fleay observed that the boobooks from Tasmania more closely resembled those of New Zealand than those from mainland Australia, though he followed Mees in treating them as a single species. Their plumage is a darker and more greyish brown overall than that of adults. Dr Clarke said saving the Norfolk Island morepork owl was vital work, despite their tiny stature and population. They can find suitable food in pine forests as well as native forest. Unexpectedly, the owls stopped breeding in 2012 and the dry spell continued until 2019. Moreporks are relatively common throughout much of New Zealand but are sparse through the eastern and central South Island. Pair of morepork chicks become first to survive in more than 10 years , Janette Norman and colleagues tested the cytochrome b DNA of three subspecies (as well as the powerful and rufous owls) to ascertain whether the closest relative was used in breeding with the last surviving female of the Norfolk boobook.

Moreporks and laughing owls were both recorded from the Punakaiki karst in small numbers, although the presence of laughing owls was inferred only from prey remains.  The cere and bill is pale blue-grey with a black cutting edge. The morepork is a small, dark, forest-dwelling owl.

On dark nights, they often perch through the middle hours, and particularly if the weather is bad, may hunt by daylight, instead. They discovered that although the Norfolk boobook was similar in plumage to the Tasmanian boobook, it was genetically much closer to the New Zealand subspecies. They also take almost any suitably sized prey, particularly small birds, rats, and mice.

In Punakaiki, one of the morepork records is of bones beneath an entrance tomo.  Leading from this, the Australian boobook was split from the Tasmanian boobook and morepork in volume 5 of the Handbook of the Birds of the World; however, several authors, including Les Christidis and Walter Boles, contested that the data had been misinterpreted from the Norman study, which had not sampled any Australian mainland boobooks at all.  The feathers of the chin and throat are buff with dark brown shafts. Its name is derived from its two-tone call. , English naturalist John Latham wrote of the New Zealand owl in his 1782 work A General Synopsis of Birds, but did not give it a binomial name. Swamp harriers could feasibly prey on young moreporks.. "It's the best outcome we could have hoped for.". Although their main hunting technique is perch-and-pounce, they are agile birds with a swift, goshawk-like wing action and the ability to maneuver rapidly when pursuing prey or hawking for insects.

"We were really concerned because there was every chance that the existing owls would get old and lose their reproductive ability," Dr Clarke said. Work began in the 1980s after the island's population declined, leaving all-but one female. , Both Gerlof Fokko Mees and Ernst Mayr regarded the taxonomy of the boobook owl as extremely challenging, the latter remarking in 1943 that it was "one of the most difficult problems I have ever encountered". Because moreporks were extremely rare in fossil deposits, Millener (1991) suggested that they were recent colonists. English naturalist John Latham wrote of the New Zealand owl in his 1782 work A General Synopsis of Birds, but did not give it a binomial name. "Now, we're on the front foot to work with these birds and find a solution to keep them going," Dr Clarke said. , It occurs in most habitats with trees, in Tasmania predominantly eucalypt forests and in New Zealand forests dominated by Podocarpus, Nothofagus, Metrosideros, and other hardwoods, up to the alpine tree line.
