A study of New Guinea's montane rainforest population concluded that it can be treated as a species separate from Australia's Logrunner. It also reported genetic differences between western and eastern highland groups within New Guinea.
The study reports that New Guinean birds are smaller and have less white on their underparts than Australian Orthonyx temminckii.
The paper identifies the New Guinean population as a bird of the island's montane rainforest.
An extinction-risk assessment has not been added yet.
