Chlorornis riefferii


20 cm
Unmistakable as the only large, bright green tanager in its range. Well named, with bright grassy green over the entire body except for a large rusty-orange mask and crissum, reddish-orange legs and beak. Sexes alike in appearance.
Juvenile duller with brown bill.


South America: found on both slopes of the Andes of Colombia, Ecuador, Bolivia and Peru.



Five subspecies are recognized1:

  • C. r. riefferii:
  • C. r. dilutus:
  • Central Andes of northernPeru
  • C. r. elegans:
  • Andes of central Peru (Junín)
  • C. r. celatus:
  • Andes of extreme south-eastern Peru (Puno)
  • C. r. bolivianus:
  • Andes of western Bolivia (La Paz and Cochabamba)


Upper subtropical and temperate forest, mostly humid to very wet; also at edges. Observed at heights around 1500-3350 m.


Characteristic horizontal perching posture.

Not easily alarmed; short flushing distance.


Often accompanies other tanagers in small flocks; fairly common and conspicuous, as it often comes into the open along forest margins to forage for fruits and insects among the branches and brush of small trees.


Builds nest from mosses and ferns.
