The subspecies C. c. frontalis , C. c. minuscula and C. c. psittacina are very similar, the females generally more or less similar.
Occurrence
The green organist is disjunct in Venezuela and Colombia to Bolivia . There are other occurrences in Ecuador , Brazil , Guyana , Argentina , Paraguay and Peru .
The species mainly lives in untouched mountain forests at altitudes of 550 to 2200 m. Plantations and gardens can also be used as habitats. The species can also be found locally in the lowlands.
