What is the coloration described for the kākāpō's plumage that provides excellent camouflage?

Answer

Gorgeous, mossy green and yellow coloration.

The kākāpō's feathers possess a specific coloration that provides essential camouflage against its forest floor habitat in New Zealand. This plumage is described as sporting a gorgeous, mossy green and yellow coloration. This effective camouflage helps the ground-dwelling, non-flying bird conceal itself from potential threats, although it has proven insufficient against the newly introduced mammalian predators against which the bird has no evolutionary defense.
