Subspecies
No subspecies.
Relationships uncertain. Has in the past been considered closely related variously to shrikes (Laniidae), starlings (Sturnidae), helmet-shrikes (Prionopidae), vangas (Vangidae), butcherbirds (Cracticidae), babblers (Timaliidae) and wood-shrikes (Tephrodornis). DNA analysis indicated close affiliation with cracticid genera Cracticus, Gymnorhina and Strepera. More recent DNA-sequencing studies, however, suggest that present species belongs to a diverse group of shrike-like birds which includes vangas, bush-shrikes (Malaconotidae), helmet-shrikes, wood-shrikes, philentomas (Philentoma), wattle-eyes (Platysteira), ioras (Aegithina) and assorted other genera, this group being sister to the cracticids and the woodswallows (Artamidae).
