Pellorneum saturatum is a ground babbler of western and central Borneo and the Bangka and Belitung islands. A 2024 Malaysian bird report describes the Glissando song as a long descending series of 20–30 rapid notes.
A specimen comparison found that two Bornean populations formerly included in Pellorneum malaccense (poliogene and saturatum) had more olive backs and wings than west Sundaland specimens, whose upperparts were more chestnut.
The Glissando form in western Borneo has a long descending song of 20–30 rapid notes. A May–September 1986 survey at Tanjung Puting in Central Kalimantan recorded it as common in inland forest and preferring dry ground. On 25 June, one juvenile was netted with an adult in kerangas forest.
