Unknown Ficedula in Namibia

The Ficedula flycatcher below was photographed in Windhoek, Namibia, on 12 October 1998. This genus is very rare anywhere in southern Africa, but the specific identification of this bird is uncertain at this time. The three species of black-and-white Ficedula flycatchers, Semi-collared (F. semitorquata), Pied (F. hypoleuca), and Collared (F. albicollis) can be extremely difficult to tell apart. Below are the circumstances of the discovery of this bird as well as a detailed list of email discussions regarding the possible identification. If this bird is a Pied or Semi-collared it would apparently represent the first record for southern Africa. If it is a Collared Flycatcher, it would be only one of a very few records of that species for the region.
