Geographical variation over species’ large range slight, despite large number of named races; in fact, there seems to be more variation within nominate than among many of proposed races. Many or most races probably not diagnosable; most described from few specimens and few localities, and many of characters used to define them seem invalid. Racial identity of birds from extreme E Peru and NE Bolivia (Pando) and others from extreme E & SE Bolivia uncertain; the first are tentatively included with purusianus, the second with connectens. Re-evaluation urgently needed. Listed distributions of several races should be interpreted with caution. Specific name has normally been given as rutilans (e.g. in HBW), but that was recently shown to be an incorrect subsequent spelling, which must give way to original spelling, rutilus#R. Eleven subspecies very tentatively recognized.
