Green-striped Brushfinch

The green-striped brushfinch (Arremon virenticeps) is a species of bird in the family Passerellidae, the New World sparrows. It is endemic to Mexico. == Taxonomy and systematics == The green-striped brushfinch has a complicated taxonomic history. It was formally described in 1855 with the binomial Buarremon virenticeps. The genus Buarremon was later merged into genus Atlapetes but further study resulted in Buarremon's being resurrected. Buarremon virenticeps was for a time assigned as one of many subspecies of what was then the "stripe-headed brushfinch" (Buarremon torquatus) but was soon restored to full species status. In 2008 taxonomists began merging Buarremon into Arremon. The green-striped brushfinch's further taxonomy is unsettled. The IOC, AviList, and BirdLife International's Handbook of the Birds of the World treat it as monotypic. However, as of late 2025 the Clements taxonomy assigns it two subspecies, the nominate A. v. virenticeps (Bonaparte, 1855) and A. v. verecundus (Moore, 1938). This article follows the monotypic species model. == Description == The green-striped brushfinch is about 17 to 19 cm (6.7 to 7.5 in) long and weighs 31 to 39 g (1.1 to 1.4 oz). The sexes have the same plumage. Adults have a black crown with a wide yellowish olive-green…
