"A deep dive into the vocalizations and phenotypes (appearance) of Brush Cuckoo Cacomantis variolosus across its wide range led to a bold new taxonomic arrangement, advanced in a recent paper (Wu et al. 2022). The new breakdown suggests Australian Brush Cuckoo Cacomantis variolosus, Sunda Brush Cuckoo Cacomantis sepulcralis, Sulawesi Brush Cuckoo Cacomantis virescens, Manus Brush Cuckoo Cacomantis blandus, and Solomons Brush Cuckoo Cacomantis addendus."
