Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor(s): BirdLife International
Reviewer(s): Symes, A. & Butchart, S.
Contributor(s): Brickle, N.
Facilitator/Compiler(s): Bird, J., Khwaja, N., Mahood, S., Pilgrim, J.
Justification:
This species is listed as Near Threatened because it may have a moderately small 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 a few locations. For these reasons, the species is classified as Near Threatened. Further information may indicate it is more threatened.

Geographic Range [top]

Range Description: Zoothera joiceyi is endemic to the island of Seram, Indonesia. It has been described as "extremely rare" (Clement and Hathway 2000), and there have been very few records (Isherwood et al. 1997). However, large areas of habitat on the island remain to be surveyed (Isherwood et al. 1997).

Population [top]

Population: The population is estimated to number 10,000-19,999 mature individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 15,000-29,999 individuals in total, rounded here to 15,000-30,000 individuals.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It inhabits montane forest at 800-1,280 m altitude (Isherwood et al. 1997). It is possible that the species is restricted to limited areas of level forest within this range (Collar 2004), where deep leaf litter is able to accumulate. It feeds alone or in pairs on the ground in deep forest undergrowth (Clement and Hathway 2000). There is no information about breeding.

Systems: Terrestrial

Threats [top]

Major Threat(s): Hill forest on Seram is considerably more secure than lowland forest, and indeed remains almost intact, with very low levels of human disturbance (Isherwood et al. 1997, N. Brickle in litt. 2005). Zoothera species are heavily traded elsewhere in Indonesia, because of their abilities as songsters, so it is likely that this threat is also impacting this species (Collar 2004, N. Brickle in litt. 2005).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
It was recorded in Manusela National Park in 1987 (Isherwood et al. 1997).

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 Manusela National Park.
