Species

Justification
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.

Taxonomic note
Stachyris plateni (Sibley and Monroe 1990, 1993) has been split into S. plateni and S. pygmaea following Collar (2006).

Identification
Identification. Small, sexes alike. Forehead, sides of face and chin black-brown with prominent white shaft streaks; hind neck, throat and upper breast red-brown with finer white shaft streaks, whole head and neck appear as a hood; back is olive brown with faint shaft streaks. 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.

Distribution and population
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.

Population justification
The global population size has not been quantified, but the species is described as uncommon to rare (del Hoyo et al. 2007).

Trend justification
A moderately rapid population decline is suspected, owing to logging and clearance for agriculture.

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.

Threats
Despite its tolerance of some habitat degradation, it is probably still threatened by logging and clearance of forest for agriculture.

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.
