Population justification: The total population is estimated to number 35,400-141,600 individuals, based on density data from extensive surveys in Esmeraldas (O. Jahn in litt. 2007, P. Mena Valenzuela in litt. 2007), extrapolated over the species's known range. This estimate is best placed precautionarily in the band 20,000-49,999 individuals, as much of the species's remaining habitat has been converted into sub-optimal secondary forest.

Trend justification: During the last decade accelerating deforestation has reduced the cover of primary forest by over 38% (Cárdenas 2007). Suspected population declines are estimated to exceed 30% for the same period (O. Jahn in litt. 2007, P. Mena V. verbally 2007).
