Genetic data#R indicate that present species and S. dougallii, S. sumatrana, S. hirundinacea, S. hirundo, S. paradisaea and S. vittata may form a monophyletic group, with S. forsteri and S. trudeaui possibly also part of this group. Validity of races requires study; species sometimes considered monotypic#R. Three subspecies currently recognized.
