Population justification: The population estimate of 250-2,500 mature individuals is derived from G. Engblom (in litt. 2003). This is roughly equivalent to 370-3,800 individuals in total. It described as uncommon to fairly common by Schulenberg et al. (2007).

Trend justification: A moderate and on-going population decline is suspected owing to rates of habitat loss and fragmentation, e.g. its habitat at Bosque Unchog has been reduced by 30-50% in the last 10-15 years (Engblom in litt. 2003).
