Justification
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Grass-green Tanager

The grass-green tanager (Chlorornis riefferii) is a small passerine bird, one of the tanager family. It is the only member of the genus Chloronis.

The grass-green tanager is 20 cm in length and weighs 53g. It lives in and around subtropical and temperate forests in the Andes of Colombia, Ecuador, Bolivia and Peru at elevations of 1500–3350 m.

It is seen in pairs or in groups of 3-6 individuals. It forages mostly on upper half of short trees and eats fruits and insects. It is known to perch almost horizontally. Its nest is made of mosses and ferns, and its eggs are gray with light purple-grey dots.
