The Bornean swamp babbler (Pellorneum macropterum) is a species of bird in the ground babbler family Pellorneidae that is found in northern and central Borneo and Banggi Island. It was formerly considered to be a subspecies of the white-chested babbler, now renamed the Malayan swamp babbler (Pellorneum rostratum).
Taxonomy
The Bornean swamp babbler was formally described in 1868 by the Italian zoologist Tommaso Salvadori based on a specimen collected in Borneo. He placed it with the shortwings in the genusBrachypteryx and coined the binomial nameBrachypteryx macroptera.[1][2] The specific epithet is from Ancient Greekmakropteros meaning "long-winged" (from makros meaning "long" and pteron meaning "wing".[3] The Bornean swamp babbler is now placed in the genus Pellorneum that was introduced in 1832 by the English naturalist William Swainson. It was formerly treated as a subspecies of the white-chested babbler (renamed the Malayan swamp babbler) (Pellorneum rostratum) but based on vocal and genetic differences it is now treated as a separate species and is considered to be monotypic: no subspecies are recognised.[4][5]
