Occasionally placed in Pluvialis, or this species and C. obscurus united in Pluviorhynchus. Has alternatively been linked with C. bicinctus. Only recently recognized taxonomically, on basis of differences in morphometrics, plumage, ecology and behaviour#R, but evidence suggests that differences are at specific level, with aquilonius smaller in size, notably in length of mid-toe and claw (from published data, effect size −2.93, score 2), yet tail marginally longer (effect size 0.42, score 1); notably paler above and below in breeding birds (2), and with greater amounts of white on face, chin and flanks (1); and nesting in coastal environments close to sea, with no nest-lining vs inland and mainly upland nesting (riverbeds, mountain tops, grassy plains) with nest lined (1). Treatment here as a species tentative and provisional, acknowledging possibility that strong clinal shift has been lost with loss of South I populations, although evidence for this may not now be recoverable#R. Monotypic.
