Has been thought probably part of a species-group with A. cuculoides, A. madagascariensis and A. jerdoni. Insular forms at W & E extremes of range tend to be smallest, but occurrence of pale and dark ones exhibits a more “chequerboard” pattern#R. Proposed races proxima (NW Solomon Is) and robusta (C Solomons) now considered better synonymized with gurneyi. NW Australian population, described as njikena, not safely separable from nominate. Thirteen subspecies currently recognized.
