Subspecies
No subspecies.
May form a superspecies with Western Scrub-Jay (Aphelocoma californica) and Florida Scrub-Jay (Aphelocoma coerulescens), and all previously treated as conspecific. Derived from coastal clade of Western Scrub-Jay (Aphelocoma californica). Relationships of this group with Ultramarine Jay (Aphelocoma ultramarina) and Unicolored Jay (Aphelocoma unicolor) yet to be resolved, as recent studies indicate that divergence of these three major lineages within the genus was apparently rapid, leading to conflict among genetic markers.
