Lake Junín, Peru.
Closely related to F. cristata, F. atra, F. alai, F. americana and F. leucoptera. Chestnut-fronted and white-fronted birds formerly treated as separate species, F. americana peruviana and F. ardesiaca, and later lumped as F. americana ardesiaca; subsequently treated as a full species, differing from americana mainly in morphology and plumage (especially pattern of undertail-coverts#R). Form peruviana is synonymized with nominate. Two subspecies recognized.
