The pointed apices of the range of P. n. xanthostomas on the left indicate the centres of overlap between it and P. carpi. (Based on data assembled for the Namibian Bird Atlas Project.) Waterberg, the two parids are locally in contact, with the Southern Black Tit confined to the moist summit levels of the upland, being replaced peripherally at lower elevations in similar but drier habitat by Carp's Tit. There is no indication that the two tits hybridize or behave in their contact zones as other than discrete species. Maps supporting these findings have kindly been made available for the present paper by Dr Brown, and form the basis for Figure 1. In the case of a second point of contact between the two tits located on the Kunene R. on the Namibian border with Angola at c. 14° 20' E, such data as are available show it to be comparable in nature to the situation present further south in the South West Arid Zone where the Acacia Grey or Ashy Tit Parus cinerascens Vieillot meets the Southern Grey Parus afer Gmelin along the Orange R., again without hybridization (see Clancey 1958). Turning to the relationship of P. carpi to the White-winged Black Tit, one is faced with a lack of supporting field evidence from critical parts of southwestern Angola. With Angola still embroiled in civil war.
