Taxonomic note
Recent mtDNA study suggests that present species is closest to C. canorus, the two being a sister-clade to C. gularis and C. rochii (Payne 2005). In 2014 Cuculus saturatus (del Hoyo and Collar 2014) incorporated C. optatus following the suggestion they were vocally indistinguishable, however the previous treatment, with both separated as species, is here reinstated after Xia et al. (2016) demonstrated that they are vocally distinct.
An earlier concept (recognised prior to 2006) treated C. saturatus (with optatus/horsfieldi: see note under C. optatus) as conspecific with C. lepidus (Sibley and Monroe 1990, 1993). Monotypic.

Population justification: The global population size has not been quantified, but is thought to be large as the species is described as 'common and widespread' in at least parts of its range (Payne 2005).
Trend justification: Remote sensing data on tree cover loss indicate that approximately 13% of tree cover with at least 50% canopy cover was lost from the species's non-breeding range, and approximately 5% from the breeding range, over the past three generations (11 years; Global Forest Watch 2021). These figures may underestimate the true rate of forest loss, especially in the non-breeding range, as the tree cover data may include plantations. However, the species has has been recorded in some types of plantation and in gardens during the non-breeding season (Payne and Kirwan 2020). The species's population size is therefore suspected to be declining at a rate of less than 20% over three generations.
