The specimen doubtfully from Kasaji is marked "?". Shading indicates equatorial rainforest block. Africa. From west of east, red progressively takes the place of certain black parts in the plumage. The most western population (S. h. haematina, in Upper Guinea) is black all around the head and has black upper tail coverts in the male. Moving east there are the races named togoensis, immaculosa and pustulata, in which red appears on the upper tail coverts of both sexes and eventually on the cheeks, the whole side of the head, in the region in front of the eyes and finally in a streak above the eye, these birds penetrating far to the east in Zaire. From the geographical distribution, it seems as if the pustulata population is pushing ruficapilla towards the east. The population in northwestern Angola (not on the map), eastern Zaire and neighbouring areas further east (ruficapilla), up to now considered as specifically distinct, has the head red all around (most intensively in the male). The specimens marked as intermediates on the map have the frontal part of the crown red, the distal part being black. They are found in areas wherefrom specimens in the contact zone between pustulata and ruficapilla are available. But 'pure' phenotypes exist in these regions as well. Head colour is the one apparent character that enables one to differentiate them. Cunningham-van Someren & Schifter (1981) described the race kilgoris from 5 specimens taken at the locality with that name (see their map), as being generally duller in colour than other Kenya specimens of.
