Subspecies
No subspecies.
Relationships disputed. Has in the past been thought to be closely related to the two species of Struthideidae, but genetic analyses indicate no such relationship. Based on recent genetic studies, has been placed in drongo family (Dicruridae) or in monarch-flycatcher family (Monarchidae), and apparent close affiliation with latter supported by details of skull morphology. Has also been suggested as being related, on basis of examination of skulls, to butcherbirds and currawongs (Cracticidae) and woodswallows (Artamidae) and, from comparison of egg-white protein, to the crows (Corvidae). Although many modern taxonomists favour placement of present genus with Monarchidae, and despite some similarities in external morphology, the two differ markedly in behaviour and nest structure. For the time being, it is considered best to retain the present family as a separate entity, although close relationship to Monarchidae appears very probable. Present species has in the past sometimes been placed in a different genus, Pomareopsis, but no apparent justification for generic separation from Magpie-lark (Grallina cyanoleuca).
