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.

Subspecies

Clements recognises the following subspecies [1]:

  • L. m. bourdilloni: "Great Eared Nightjar". South-western India
  • L. m. cerviniceps: "Great Eared Nightjar". Bangladesh and north-eastern India to southern China, Indochina and northern Malay Peninsula
  • L. m. jacobsoni: "Simeulue Eared Nightjar". Simeulue Island (off north-western Sumatra)
  • L. m. macrotis: "Philippine Eared Nightjar". Northern and eastern Philippine Islands
  • L. m. macropterus: "Sulawesi Eared Nightjar". Sulawesi, Talaud Island, Sangihe Island, Banggai Island and Sula Island

Habitat

Primary and secondary forest and forest edges, often near water.

Behaviour

Diet

Their diet includes moths, beetles, termites etc. The hawk for these over forest clearings and nearby fields.
