Population justification: The population is estimated to number 2,500-9,999 mature individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.

Trend justification: This species is showing declines within its known range. Habitat continues to be destroyed at several sites (R. Williams in litt. 2003) with a current rate of forest loss in western Ecuador of 57% per decade. Overall, rapid declines are suspected based on rates of forest loss across the entire range.
