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: The decline in Colombia is estimated to be 78% during 1992-2002, based on rates of habitat loss (Renjifo et al. 2002). The decline in Ecuador remains unquantified, but the overall rate is likely to be at least 30-49% over ten years. |
