Subspecies
No subspecies.
Forms a superspecies with Eurasian Magpie (Pica pica), Asir Magpie (Pica asirensis) and Yellow-billed Magpie (Pica nutalli), and often treated as conspecific with Eurasian Magpie (Pica pica) or all of those. Recent analysis of mitochondrial genome suggests that Yellow-billed Magpie (Pica nutalli) is a sister-taxon, closely related to Eurasian Magpie (Pica pica), the three exhibiting low average divergence (only 2.35%), suggesting that they may be better considered conspecific.
