P. gymnocephalus P. oreas Galgulus Wagler, 1827 (non Brisson, 1760: preoccupied) The picathartes, rockfowl, or bald crows are a small genus of two passerine bird species forming the family Picathartidae found in the rain-forests of tropical west and central Africa.

[2] Serle in 1952 thought it resembled the Asian genus Eupetes while Sibley used egg-albumin protein similarity, determined by electrophoresis, to suggest that it belonged to the Timaliidae.

[3] A molecular sequence based study suggests that it may indeed be closely related to the crows and placed somewhere at the boundary between the Passerida and Corvida.

[4] More specifically they appear to be a sister of the rockjumpers (Chaetops) and are basal to the clade containing the Sylvioidea, Passeroidea and Muscicapoidea but outside the core Corvoidea.

The strong feet and grey legs are adapted to terrestrial movement, and the family progresses through the forest with long bounds on the ground.

The plumage is similar between the two species, with white breasts and bellies and darker grey and grey-black wings, backs, and tails.

Prey items include a range of insects, particularly beetles, termites, and ants, as well as millipedes, centipedes, earthworms, and gastropods.

These birds require forest litter for foraging, a large enough area to contain army-ant swarms (Dorylinae), and rocks, cliffs, or caves for nesting sites.
