Picathartes gymnocephalus; Print; The white-necked rockfowl (Picathartes gymnocephalus) is a medium-sized bird in the family Picathartidae; with a long neck and tail. Also known as the white-necked picathartes; this passerine is mainly found in rocky forested areas at higher altitudes in West Africa from Guinea to Ghana. Its distribution is patchy; with populations often being isolated from each other. The rockfowl typically chooses to live near streams and inselbergs. It has no recognized subspecies; though some believe that it forms a superspecies with the grey-necked rockfowl. The white-necked rockfowl has greyish-black upperparts and white underparts. Its unusually long; dark brown tail is used for balance; and its thighs are muscular. The head is nearly featherless; with the exposed skin being bright yellow except for two large; circular black patches located just behind the eyes. Though the bird is usually silent; some calls are known.; 1872
