It is endemic to Lord Howe Island in the Tasman Sea, part of New South Wales, Australia, and is a threatened subspecies of the pied currawong.

Compared with the nominate subspecies of eastern Australia it has a longer and more slender bill, less white on the wings and tail, and a paler iris.

[3][4] The Lord Howe currawong has a strong sense of curiosity, often following walkers on the island's tracks.

[6] The currawong breeds in territories in the forest that contain a section of gully or watercourse lined with tall timber.

[10] The taxon is listed as Vulnerable under Australia's EPBC Act because of its small and restricted population and occasional persecution due to its predatory habits.
