Population justification: Based on the smalll 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 show that the population is larger than this though.
Trend justification: A slow and ongoing population decline is suspected, owing to habitat loss, although if the species is proven to favour secondary growth, suitable habitat may actually be increasing in areas such as the Sierra de Perijá (C. J. Sharpe in litt. 2011).
