Justification of Red List category
This species has a large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence under 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 size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (under 10,000 mature individuals with a continuing decline estimated to be over 10% in ten years or three generations, or with a specified population structure). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (over 30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern.

Population justification
The global population size has not been quantified, but the species was described as moderately common to common in lowland forests throughout its range, prior to being split (del Hoyo et al. 2006). This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 7% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Therefore, as a precautionary measure, it is tentatively suspected that this loss of cover may have led to a decline of between 1-19% in the species' population size over the same time frame.

Trend justification
  .

Rhipidura cockerelli occurs on Bougainville in Papua New Guinea and most of the Solomon Islands where it occurs at low population densities (Schodde 1977, Blaber 1990, Webb 1992, Buckingham et al. 1995, G. Dutson pers. obs. 1997-1998, Hornbuckle 1999, Dutson 2011).

It occurs in primary and closed secondary forest and forest edge to about 1,150 m.It is fairly uncommon and intolerant of degraded forest.

Most of the lowland forests across the Solomons have been logged or are threatened with logging and this species would be threatened by any increase in the rate of deforestation.

Conservation Actions Underway
None is known.

Conservation Actions Proposed
Conduct surveys to determine population trends. Determine habitat requirements and susceptibility to logging. Ascertain the area of forest and rates of clearance across the islands within its range. Ensure protection of significant areas of lowland forest on each of the islands where it occurs.
