Authorship of original description previously given as Shaw and Nodder, 1790, but recent investigation found that Shaw, 1808 is correct#R. Thought to form a species-group with A. coronatus and A. marchei. Was for long confused with A. coronatus, with complex synonymy of both scientific and vernacular names; the two were considered conspecific, but now recognized as two distinct species, differing in size and in several aspects of morphology (including colour of bare throat skin) and behaviour, and overlapping in range without interbreeding. During period of confusion, present species was commonly referred to as A. malabaricus, but this name, two years senior to albirostris, appears to be unidentifiable; within “A. malabaricus”, E birds were sometimes separated as race leucogaster, now considered a junior synonym of albirostris. Race convexus sometimes considered a separate species, but alleged sympatry without hybridization apparently not proven, and supposed difference in tail pattern not constant. Two subspecies recognized.
