One individual was documented in a bamboo patch in Misiones, northeastern Argentina. The description here follows that local observation.
The observed bird had a cream breast with faint gray streaks, a dark cream-olive back, and greener wings.
The bird perched upright and made short, noisy flights about 0.5–2 m above the ground in bamboo. The patch contained Chusquea bamboo among laurel and guatambu forest.
An extinction-risk assessment has not been added yet.
