Justification of Red List category
This species is listed as Near Threatened because there are some indications that it has a moderately small, fragmented population within its small range, and it is undergoing a continuing decline owing to trapping. However, the range is not yet severely fragmented or restricted to few locations, and so the species does not currently merit a higher threat category. Further information may indicate it is more threatened.

Population justification
Population estimate = 20 individuals/km² x 1,700 km² (20% of EOO) = 34,400 individuals (density range from up to lower quartile of two Asian congeners in BirdLife Bird Population Density Spreadsheet). Perhaps best currently placed in population band of 20,000-49,999 individuals.

Trend justification
Although data are very poor, the species may be declining owing to the bird trade.

Geokichla dumasi is endemic to the island of Buru, Indonesia. Little is known about the species, and although it has been described as not uncommon (Clement and Hathway 2000), there have been few recent records. Tracewski et al. (2016) estimated the maximum Area of Occupancy (calculated as the remaining tree area within the species’s range) to be c.1,543 km², rounded here to 1,500 km².

It inhabits dense, lower montane moss-forest, most commonly at 725-1,500 m altitude. It has been suggested that the species is largely restricted to limited areas of level forest within this range (Collar 2004), but it has certainly been seen on steep slopes (F. Lambert in litt. 2005). It feeds alone or in pairs on the ground in deep forest undergrowth (Clement and Hathway 2000). Eggs have been recorded in February, and young in early April (Clement and Hathway 2000).

Hill forest on Buru is considerably more secure than lowland forest, and indeed remains almost intact. Zoothera species are heavily traded elsewhere in Indonesia, because of their abilities as songsters, so it is likely that this is a threat to the species (Collar 2004, N. Brickle in litt. 2005).

Conservation Actions Underway
Gunung Kelapat Muda Game Reserve presumably contains a population of this species.

Conservation Actions Proposed
Conduct further surveys to assess the full extent of occurrence of this species, its specific habitat requirements, and its overall population size. Assess the extent to which bird trade is a threat. Effectively protect suitable forest within its range.

17 cm. A medium-sized thrush. Russet crown, nape, and mantle, and dark brown wings, and face to belly. Belly whitish. Broad white tips to greater and median wing-coverts. Similar spp. None in range. Seram Thrush Z. joiceyi similar, but has dark brown mantle and white tips only to median wing-coverts. Voice Generally silent, but gives an easily overlooked thin tseep contact note and tsree-tsree flight call.
