Until recently treated as conspecific with C. laeta, and also included C. parkeri as a highland population. Recent comprehensive molecular study#R indicates it is closest to C. serva. At least some of plumage differences on which races were based appear due to clinal variation; analysis of other parameters required in order to define geographical populations more accurately, so ranges listed are provisional. Vocal differences between populations of Middle America plus Magdalena Valley (Colombia) and other taxa/populations in South America merit investigation#R. Proposed race rufiventris (E Panama) included in nominate, based on study of plumage variation. Four subspecies recognized.
