Taxonomie

The great eared nightjar was formally described in 1831 by the Irish zoologist Nicholas Aylward Vigors based on a sample collected in the neighbourhood of Manila in the Philippines. Vigors coined the binomial name Caprimulgus macrotis. The great eared nightjar was formerly placed in the genus Eurostopodus. It and the closely related Malaysian eared nightjar were moved to the resurrected genus Lyncornis based on the results of a molecular phylogenetic study published in 2010 that found large genetic differences between the great eared nightjar and other species in Eurostopodus. The genus name Lyncornis combines the Ancient Greek lunx / lunkos (meaning "lynx") with ornis, meaning "bird". The specific epithet macrotis is from the Ancient Greek makrōtēs, meaning "long-eared" (from makros meaning "long" and ous, ōtos meaning "ear").<p>Five subspecies are recognised:
