Uncommon brushfinch restricted to the high Andes of northern and central Peru. Adult is mostly gray with a chestnut cap, black-and-white mustache stripes, and a white spot in front of the eye. Young birds are washed with brown and have a duller crown. This species does not overlap with Black-spectacled Brushfinch or Apurimac Brushfinch, both of which have black around the eye. Inhabits woodland understory and patches of scrub. Gives rich, descending trills along with high-pitched “sip” notes.
