About the Aberrant Bush-Warbler

The aberrant bush warbler (Horornis flavolivaceus) is a species in the bush warbler family, Cettiidae. It was formerly included in the "Old World warbler" assemblage. It is found in central and southern China, and the northern extremes of Myanmar and Vietnam. It occurs in the countries of Bhutan, China, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Philippines, Thailand, Timor-Leste and Vietnam and also may occur in northeastern and southeastern Bangladesh.

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. The specific epithet flavolivaceus combines the Latin flavus meaning "yellow" with the Modern Latin olivaceus meaning "olive-green". The aberrant bush warbler is now placed in the genus Horornis that was introduced in 1845 by Brian Hodgson.
