Population justification: The species is described as uncommon to locally fairly common (Stotz et al. 1996, Schulenberg et al. 2007, B. Winger in litt. 2012). Assuming that the species occurs at the same density as a congener, Variegated Antpitta G. varia (3 mature individuals/km2; Santini et al. 2018), the population may number c. 90,000 mature individuals.

Trend justification: The population trend for this species has not been directly estimated. Tree cover within the range has been lost at a rate of 3% over the past three generations (15 years; Global Forest Watch 2020). The species is strictly forest-dependent; it is therefore conceivable that the rate of population decline exceeds the rate of forest loss. It is here tentatively suspected that the species is declining at up to 10% over three generations.
