Dear RICHARD, SWANS are not necessarily white, and all DRONGOS not necessarily black. _______________________ Thanks for showing us this exotic glossy (in India termed 'Spangled') EMERALD Drongo species. With ruff-like gelly feathers (mane?) around the face, a crest of at least one spectacular 'hair' + a Curved vintage-car tail-design! PS Drongos may be aggressive and mimic calls of other birds. This Asian species stands out with straight 'hairs' : WHY is it termed HOTTENTOTTUS? KR ........... C.
