Taxonomy
Reference [3] uses an integrative approach to recommend splitting the species into 4: "Great Eared Nightjar", L. cerviniceps (sspp. bourdilloni, cerviniceps); "Simeulue Eared Nightjar", L. jacobsoni (jacobsoni); "Sulawesi Eared Nightjar", L. macropterus (macropterus) and "Philippine Eared Nightjar", L. macrotis (macrotis). It concludes that bourdilloni should be treated as a synonym of cerviniceps. Subspecies jacobsoni is genetically and vocally very close to cerviniceps but shows marked plumage differences. In contrast, subspecies macrotis and macropterus are indistinguishable but have deep divergent mitochondrial DNA and different vocalisations.
Reference [4] notes the species has been split into western and eastern species by some authors ("Monsoon Eared-nightjar", L. cerviniceps; subspecies bourdilloni, cerviniceps, jacobsoni, and "Pacific Eared-nightjar", L. macrotis; subspecies macrotis and macropteris respectively).
This taxon was formerly placed in the genus Eurostopodus.
