Subspecies
Affinities uncertain. Closest relative probably Luzon Boobook (Ninox philippensis). Considered by some authors to be close to Speckled Boobook (Ninox punctulata), but this apparently far from the case. Sometimes referred to as Ninox perversa, as name ochracea erroneously thought to be preoccupied.
