Victoria Falls, north-western Zimbabwe.
Sometimes placed in genus Thamnolaea or Pentholaea. Race harterti distinctive; if vocally different, may merit species status, but intermediates appear to exist in S areas where nominate approaches it. Race leucolaema recently revived (citing the name collaris, a synonym) and proposed for species rank#R; but morphological distinctiveness not so strong, and further work needed on vocalizations and ecology. Named after David Arnot#R, but species name can not be emended, as internal evidence only reinforces the misspelling by referring to "Mr Arnott". Three subspecies recognized.
