Justification:
This species has been listed as Near Threatened owing to concerns that it is undergoing a moderately rapid population reduction, as a result of trapping for the bird trade, and forest loss and degradation. Trends in forest loss and trapping levels need monitoring, and its tolerance of degraded forest should be determined. With this information it may require uplisting to Vulnerable.

Geographic Range [top]

Range Description:	Zoothera interpres is found discontinuously from southern peninsular Thailand and Malaysia, through Borneo (including Brunei Darussalam), Sumatra and Java, to Lombok, Sumbawa and Flores, in Indonesia. It may also be a rare resident on several of the south-west Sulu Islands and Basilan in the central-southern Philippines. It is described as "generally rare and scarce" (Clement and Hathway 2000) throughout, and there are very few records from Sumatra and Kalimantan in particular, although it is probably under-recorded to some extent. It was formerly not uncommon in the Lesser Sundas and in Sabah (Malaysia), but is thought to have undergone a rapid decline in recent years owing to logging and trapping for the cage bird trade.

Population [top]

Population:	The global population size has not been quantified, but the species is described as locally fairly common in the Lesser Sundas and Borneo, rare in Thailand and the Philippines and local and scarce in Peninsular Malaysia (del Hoyo et al. 2005).
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It inhabits lowland primary deciduous and evergreen forest, often with a dense understorey, but has also been found in partially degraded forest and forest fragments (Clement and Hathway 2000). Usually forages for invertebrates on the ground, but occasionally seen in fruiting trees (Clement and Hathway 2000). Breeding takes place from April or May to about late July or August, but probably with regional variation (Clement and Hathway 2000). Nest with 2-3 eggs placed up to 4 m above the ground (Clement and Hathway 2000).
Systems:	Terrestrial

Threats [top]

Major Threat(s):	Significant habitat loss is ongoing throughout the lowland forest range of this species, and studies from Sabah indicate that it occurs at a much lower density in logged forest (D. Edwards in litt. 2007). In recent years it has been very heavily exploited for the cage-bird trade, raising fears of its extirpation from some islands in Nusa Tenggara (Clement and Hathway 2000).
