The wings and tail are brown, edged with olive; lower belly and undertail white. Bill blue-grey with white tip. Eyes are lined by pinkish orange ring, becoming fainter in colour towards the pupil. Legs grey. Similar species. Small size and streaking on throat and white belly separate Stachyris plateni from the Brown Tit-babbler. Black crowned and Rusty-crowned Babblers differ in yellow throat colouring. Voice. A twittering series of six or more notes chi-chi-chi chi chi chi descending and slowing down over 1.5 seconds.

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2016
Date Assessed: 2016-10-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Facilitator/Compiler(s): Mahood, S., Taylor, J.
This species has been classified as Near Threatened because, although it tolerates some habitat degradation, it is likely to be undergoing a moderately rapid population reduction owing to on-going logging and clearance for agriculture.

Geographic Range [top]

Range Description:Stachyris plateni is endemic to the island of Mindanao, the Philippines, it was formerly considered conspecific with S. pygmaeus. It has been recorded from a number of sites including: Kalambogan, Malabang, Mt Malindang, Mt Piapayungan, Mt Agtuuganon, Mt Apo, Mt Matutum, plus Mt Hilong-hilong, Mt Kitanglad, Cabanglasan, Bukidnon, Tu-od and Na-awan, Misamis Oriental, Mt Lamut, Bislig at PICOP and Lake Sebu. It appears to be uncommon to rare throughout its range.

Habitat and Ecology [top]

Habitat and Ecology:It occupies primary forest, adjacent secondary growth and trees in cultivated areas; at 100-1,100 m. It feeds on insects and small fruit. It breeds during March-May.

Continuing decline in area, extent and/or quality of habitat:Unknown
Generation Length (years):3.7
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): Despite its tolerance of some habitat degradation, it is probably still threatened by logging and clearance of forest for agriculture.

Conservation Actions: Conservation Actions Underway
It occurs in a number of protected areas.

Conservation Actions Proposed
Effectively protect forest at known sites. Further research its tolerance of degraded habitats.
