Population justification: Based on the small number of birds recorded at the two known locations, e.g. with 6-7 pairs heard along a 2 km stretch of road at Ocaña (O. Laverde in litt. 2006), the total is probably best placed precautionarily in the band 250-999 individuals. This equates to 167-666 mature individuals, rounded here to 150-700 mature individuals. Further surveys may however show that the population is larger.

Trend justification: The species is suspected to undergo a slow decline due to habitat loss (Renjifo et al. 2016).
