French: Coucou des buissons German: Buschkuckuck Spanish: Cuco Varioloso
Other common names: Square-tailed/Grey-headed Cuckoo; Indonesian/Rusty-breasted (Brush) Cuckoo (sepulcralis)

Taxonomy: Cuculus variolosus Vigors and Horsfield, 1827, Paramatta, New South Wales.
Sometimes placed in Cuculus. Form sepulcralis (incorporating everetti, virescens, aeruginosus, infaustus) is often treated as a distinct species on grounds of claimed morphological and vocal differences; sometimes reckoned to be closer to C. merulinus. Several additional island races have been described, but are nowadays considered invalid. Eleven subspecies recognized.
