Justification of Red List category
Although this species may have a restricted range, it is not believed to 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 is unknown given recent taxonomic splits. This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 6.8% 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 1-9% in the species' population size over the same time frame.
Trend justification
.
Restricted to the island of Guadalcanal in the east Solomon Islands.
Occurs in forested habitats, not necessarily near watercourses and may tolerate secondary forest and plantations as noted in other Ceyx (del Hoyo et al.2001).
14 cm. A small blue and orange kingfisher restricted to Guadalcanal, E. Solomans. The massive bill is largely black, but with an orange base to the lower mandible. The underparts are a pale orange-buff, becoming white on the throat. Lores are orange, and there is an orange and white patch behind the ear coverts. The rest of the head and upperparts are dark blue. Similar species. C. meeki and C. mulcatus both have entirely black bills. C. sacerdotis of New Britain has the entire lower mandible orange.
