White-throated oxylabes
Template:Short description Template:Speciesbox
The white-throated oxylabes (Oxylabes madagascariensis) is a species of passerine bird that is endemic to Madagascar. It is the only species placed in the genus Oxylabes. Formerly considered as a member of the Old World warbler family Sylviidae, it has been moved to the family Bernieridae — the Malagasy warblers.[1] Its natural habitat is subtropical or tropical moist lowland forests.[2]
Taxonomy
In 1760 the French zoologist Mathurin Jacques Brisson included a description and an illustration of the white-throated oxylabes in the third volume of his Ornithologie based on a specimen collected on the island of Madagascar. He used the French name Le rossignol de Madagascar and the Latin name Luscinia madagascariensis.[3] Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature.[4] When in 1789 the German naturalist Johann Friedrich Gmelin revised and expanded Carl Linnaeus's Systema Naturae he included the white-throated oxylabes based on Brisson's description. He placed it with the wagtails in the genus Motacilla and coined the binomial name Motacilla madagascariensis.[5] The white-throated oxylabes is now the only species placed in the genus Oxylabes that was introduced in 1870 by the English ornithologist Richard Bowdler Sharpe.[6][7] The genus name is from Ancient Greek oxulabēs meaning "quick at seizing".[8] The species is monotypic: no subspecies are recognised.[7]
In 2013, genetic studies determined that the Bluntschli's vanga (also known as short-toed nuthatch-vanga), a species described in 1996 from two specimens collected in 1931, was actually this species. The specimens were both juveniles in a poorly known brown plumage.[9]
