An unusual long-necked, long-tailed guineafowl with a mostly naked head. The blue breast is overlaid with long black-and-white feathers, and there is a chestnut patch on the nape. Immatures are duller and brownish, but usually associate with adults. The call is an agitated-sounding up-and-down rattling series, similar to the call of Helmeted Guineafowl, but higher-pitched.
