Population justification: Recent surveys recorded the species at a density of 2-3 birds/km2; estimates based on this data place the population at 500-1,200 individuals (O. Cortes in litt. 2012), roughly equivalent to 330-800 mature individuals.

Trend justification: On-going habitat loss, degradation and disturbance in its range suggest that this species's population has undergone at least a moderate decline over the last 10 years (O. Cortes in litt. 2011). Worsening pressures on the species's habitat could lead to a reduction of c.30% in the species's Extent of Occurrence over the next 10-15 years (Fundación ProAves in press), thus the population is expected to undergo a moderately rapid decline over this period.
