Population justification: The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996).

Trend justification: Freile et al. (2010) predict a population decline of 10-30% over the next three generations, estimated by BirdLife to be 11 years, based on the likely rate of habitat loss (c.290-870 km2 over 10.5 years), thus the species may qualify as Near Threatened under criterion A3c (typically a 20-29% decline over three generations). Of the 18 antpitta species studied by Freile et al. (2010), G. watkinsi had experienced the greatest extent of habitat loss in Ecuador, at 63%. Despite its ability to survive in secondary habitats, the critical degree of habitat degradation that has occurred throughout its range in recent decades has reportedly resulted in the complete devastation of all vegetation cover in large areas (Freile et al. 2010). The species can inhabit dense regenerating scrub and secondary forest, indicating a moderate to high tolerance of habitat degradation and disturbance; however, it is absent from areas described as completely modified or forest patches frequented by livestock. In western Ecuador, remnant forests are generally small and the level of habitat protection is regarded as limited (Freile et al. 2010).
