To Dr. Burmeister we owe the discovery of this brilliant Finch, as of so many other Argentine species. He met with it at Paraná, in the bushy lands east of the city, and obtained five specimens. White found it near [Andalgala] in Catamarca, on trees, feeding on the insects in the flowers and on seeds; and Durnford collected specimens near Salta.
Examples of this species were also obtained by Weisshaupt near Mendoza (cf. Salvin, Ibis, 1880, p. 355).
