Taxonomy H. f. vulcanius The aberrant bush warbler was formally described in 1845 by the English zoologist Edward Blyth based on a specimen collected in Nepal. He placed the species in the genus Neornis and coined the binomial name Neornis flavolivacea .[ 4] [ 5] The specific epithet flavolivaceus combines the Latin flavus meaning "yellow" with the Modern Latin olivaceus meaning "olive-green".[ 6] The aberrant bush warbler is now placed in the genus Horornis that was introduced in 1845 by Brian Hodgson .[ 7]
