Justification of Red List Category
Despite having a restricted range, this species is not thought to 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). Despite the population trend appearing to be decreasing, the decline is not thought to 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 it is not believed to approach the thresholds 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.
The population size is unknown, but the species is described as locally common on Yamdena (Clement 2016).
The population trend has not been estimated but a decline due to habitat loss is suspected.
Ficedula riedeli occurs on Larat and Yamdena in the Tanimbar Islands of Indonesia (Clement 2016).
It occurs in the understorey and bamboo within lowland and lower montane forest.
Habitat loss is the main threat to the species.
Conservation Actions Proposed
Estimate the species's population size and the rate at which it is declining. Protect suitable areas of habitat.
