Until recently considered conspecific with C. diomedea and C. borealis, but differs from both in its thin greyish (vs thick yellow) bill with blackish subterminal band (3); darker and greyer brown upperparts, often with dark W-mark across upperwing (2); clean demarcation between dark upper and white lower parts of head, thus sometimes creating capped appearance (1); smaller and slimmer size, with longer tail, smaller head, slightly narrower wings (at least 1); uppertail-coverts tending to show more white (ns[1]); possibly shallower wingbeats, wings held slightly more forward, hand at right angles to body when gliding (ns)#R#R. Monotypic.
