A small tanager that is rare and local in the Andes of Colombia. Beautiful male is patterned in electric cerulean and black with an especially prominent black mask and a staring yellow eye. Female is grayish brown above and dull buffy below with a darker mask and a yellowish eye. Note its rather stout bill for a dacnis. Pairs occur in montane forest and edges from around 1,300 to 2,200 m, where they follow mixed-species flocks or feed from fruiting trees.
