About the Gray-browed Brushfinch

The grey-browed brushfinch (Arremon assimilis) is a species of bird in the family Passerellidae, the New World sparrows. It is found in Colombia, Ecuador, Peru and Venezuela. The grey-browed brushfinch has a complicated taxonomic history. It was formally described in 1840 with the binomial Tanagra (Arrémon, Vieillot; Embernagra, Lesson) assimilis. It was later reassigned to the genus Buarremon that was later merged into genus Atlapetes. Further study resulted in Buarremon's being resurrected. Buarremon assimilis was later reassigned as one of many subspecies of what was then the "stripe-headed brushfinch" (Buarremon torquatus). In 2008 taxonomists began merging Buarremon into Arremon. Following a study published in 2010 and some earlier studies, taxonomists began splitting the "stripe-headed brushfinch" into eight species, one of which was the grey-browed brushfinch.

The grey-browed brushfinch has these four subspecies: A. a. larensis (Phelps, WH & Phelps, WH Jr, 1949) A. a. assimilis (Boissonneau, 1840) A. a. nigrifrons (Chapman, 1923) A. a. poliophrys (Berlepsch & Stolzmann, 1896) A 2014 publication suggested that A. a. larensis might be a full species...
