Other common names: Black-billed Ground-tyrant
Taxonomy:
P [epoaza] Montana d’Orbigny and Lafresnaye, 1837, Chuquisaca, Bolivia.
Race intermedius is likely to be a clinal variant of insolens, nominate and maritimus, as it is phenotypically and geographically intermediate between these three races and does not exhibit a constant set of diagnosable features. Described race leucurus (from Patagonia) merged with maritimus, from which it appears indistinguishable. Five subspecies currently recognized.
