Population justification: The species has been described as fairly common (Gallo-Cajiao and López-O. 2014), but given that the area of suitable habitat is thought to be less than 10 km², the total population size is presumably very small. Based on known densities of the congeneric E. derbyi (20−90 birds per km² [Cresswell et al. 1999]), it has been estimated at up to 900 individuals (Gallo-Cajiao and López-O. 2014, Fjeldså and Sharpe 2015), which roughly equates to 600 mature individuals, placed here in the band 250-999 mature individuals.

Trend justification: The population is suspected to be decreasing owing to habitat loss and degradation, however the rate of decline has not been quantified.
