Justification of Red List Category
This species is listed as Near Threatened because there are some indications that its population is fragmented and undergoing a continuing moderately rapid decline owing to trapping and loss of lowland forest. However, little is currently known about the population size of and the threats to this species. Further information may indicate it is more threatened.
The global population size has not been quantified, but the species is described as generally common (del Hoyo et al. 2005).
This species is assumed to be declining moderately rapidly because it occurs in lowland forest which is decreasing in extent and quality owing to logging pressure, and it may suffer from hunting pressure which may increase in the future.
Zoothera peronii is restricted to the Banda Sea Islands, Indonesia and Timor-Leste, where it is generally common on Roti and West Timor (race peronii), Timor-Leste, Wetar and Romang, Babar and Damar (race audacis).
It occurs up to 1,200 m in forest (including monsoon forest). Although it has been found in degraded patches, it appears to favour areas with closed-canopy forest, which are constantly diminishing. It is largely terrestrial and solitary but will aggregate in small numbers if feeding in fruiting trees. Seen in the mid and upper canopies as well as on the ground.
Primary lowland forests are exploited within the species's range and the number of fragments continues to decrease. Heavy trade in Zoothera species in West Timor is likely to be affecting this species, although it appears to be safe from this threat in some parts of its range, such as Wetar (Trainor et al. 2009).
