Justification of Red List category
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population is considered stable and hence does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but is likely to be small. Nevertheless, it does not qualify for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Population justification
The global population size has not been quantified, but the species is thought to occur at lower densities, described as generally uncommon but easily overlooked (del Hoyo et al. 2005, C. Trainor in litt 2020).
Trend justification
Forests within the range of the species are not thought to be under imminent threat. Recent fores loss estimates remain low at <5% (Tracewski et al. 2016, Global Forest Watch 2020) over a 3-generation period (14.1 years; Bird et al. 2020). It also occurs in secondary forests and edges. The population is therefore suspected to be stable in the absence of evidence for any substantial declines or threats.
Edolisoma dispar is restricted to the Banda Sea Islands Endemic Bird Area, Indonesia, where it occurs on the islands of Romang, Damar, Tanimbar, Kai, Seram Laut/Watubela and Banda, with a recent potential sound recording from Babar too (Trainor and Verbelen 2013). It is apparently generally uncommon, but may be locally numerous and is easily overlooked.
This species inhabits forest, forest edge and secondary woodland, up to 1,400 m.
Forest loss remains low within the species's range. It is also not considered to be threatened by hunting (C. Trainor in litt. 2020).
Conservation Actions Underway
No targeted conservation actions are known for this species, although some of its habitat is protected.
Conservation Actions Proposed
Conduct repeated surveys in areas within and surrounding the species's range to determine current distribution and abundance, as well as assess population trends and rates of habitat loss. Conduct ecological studies to improve understanding of its precise habitat requirements, tolerance of secondary habitats and response to fragmentation. Protect areas of suitable habitat and safeguard against any threats.
