Population justification: The population size has not been quantified however estimates range from fewer than 2,500 individuals (del Hoyo et al. 2004) to fewer than 250 individuals (Cuervo 2014). It is precautionarily placed in the band 50-249 individuals.

Trend justification: The population is suspected to be in moderate decline owing to on-going habitat destruction. According to Cuervo (2014) a combination of rapid deforestation and fragmentation suggests the population could decrease by 30% in ten years.
