 It is mostly found on the roughest lava, but also wanders into the open spaces in the forest.I never heard it sing (once mistook the young "Rhodacanthis" -greater koa finch song for that of "Chloridops"), but my boy informed me that he had heard it once, and its song was not like that of "Rhodocanthis".Only once did I see it display any real activity, when a male and female were in active pursuit of one another amongst the sandal-trees.
