Family Cuckoos (Cuculidae)

Near Threatened

Bornean Ground-cuckoo (Carpococcyx radiceus)


French: Calobate radieux German: Laufkuckuck Spanish: Cuco terrestre de Borneo
Other common names: Sunda Ground-cuckoo (when lumped with Carpococcyx viridis)

Calobates radiceus


, 1832,

Pontianak district, western Borneo


Original spelling, radiceus, is almost certainly an error for radiatus or radiosus, both names having been applied to the taxon in other writings by Temminck himself; however, internal evidence of original description is insufficient to justify emendation, or indeed to clarify which alternative might have been intended; radiatus has been used by some authors, including HBW. This species formerly treated as conspecific with C. viridis, but is clearly larger and shows distinct plumage differences from latter at all ages. Monotypic.
