Kulla, northern Ethiopia.
Thought to be part of a clade with C. senegalensis, C. cupreicaudus and C. superciliosus#R. Possible intermediates occur between present species and C. cupreicaudus, and their vocalizations are similar; on occasion treated as conspecific. Race occidentalis sometimes considered indistinguishable from fischeri. Proposed race heuglini (from large permanent swamps in Sudan), with blue (not violet) head, appears to represent an immature plumage of fischeri; birds of N Angola previously separated as race angolensis; birds from SW DRCongo (Shaba) described as supposedly smaller race verheyeni, but in fact overlap in size with fischeri. Three subspecies currently recognized.
