Taxonomic note

Ceblepyris cinereus and C. cucullatus (del Hoyo and Collar 2016) were previously lumped as Coracina cinerea following Dowsett & Forbes-Watson (1993) and Sibley & Monroe (1990, 1993).

Population justification: Given its very restricted range (Extent of Occurrence = 1,206 km²), the population is not thought to exceed 2,500 mature individuals. The suspected population size is thus placed in the band 1,000-2,500 mature individuals.

Trend justification: This population is inferred to be in decline owing to habitat destruction (del Hoyo et al. 2005; Ibouroi et al. 2019). The likely rate of decline however, has not been estimated.
