been described as a continuous, low-pitched, guttural chatter similar to "ow, ow, ow". Adults and juveniles have also been known to produce a long-drawn "owooh" call note. Additionally, fledglings can give a loud, quavering second-long whistle as a contact call. Distribution and habitat This species is only found in West Africa from Guinea to Ghana. It is locally common in southeastern Guinea, and is widespread in Sierra Leone except for the north and northwest, and in Liberia except for the north and northeast. In Côte d'Ivoire the species is currently restricted to areas near the Guinean and Liberian border. The bird also lives in Ghana, where it is both local and uncommon in the south central parts of the nation. The white-necked rockfowl's total range covers approximately . However, the species occurs in low population densities in patches across this large range. The species does not migrate, though it does disperse widely after the breeding season. This rockfowl lives on steep slopes in both primary and mature secondary forests. These forests are typically covered in rocks and are found in hilly lowland areas up to . The white-necked rockfowl often lives near flowing streams and rivers so that it has access to wet mud for nest construction. Colonies are typically found within of a stream. The species also seems to show a preference for living near inselbergs. Rockfowl are occasionally seen in partly cleared forests and near cities, but this appears to be abnormal. Recent surveys have shown that abandoned rockfowl nests are more likely to be in or near secondary forest. Ecology and behavior This picathartes typically keeps low in the vegetation or on the ground near its nesting grounds. It moves quickly through its forested habitat primarily through a series of hops and bounds, followed by a pause before resuming its movements. It uses its tail for balance while traversing the forest. The rockfowl also flies at a low altitude for short distances between vines and trees, and it rarely flies for long distances. This species can disappear from sight into a mass of creepers or rocks. It is capable of high jumps, sometimes jumping off the cave floor to its nest while only partly using its wings. It was once thought that the rockfowl rarely ventures far from its breeding grounds; however, new data suggests that the species has a much broader range than previously thought. Rockfowl
