Population justification: The population has been estimated at <10,000 breeding pairs (Brazil 2009), or <20,000 mature individuals. It is therefore placed in the band 10,000-19,999 mature individuals.

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and degradation.
