Population justification: Preliminary population estimates best place the global population in the band 10,000-19,999 individuals (S. Koenig in litt. 2008). This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals. Further studies are required to obtain an accurate figure.

Trend justification: Data suggests a decline of at least 50% may occur over the next 40-50 years as a result of habitat destruction due to three proposed mining concessions, two of which have recently been granted (Koenig, 2008). However, it is not certain whether the third concession will be granted (S. Koenig in litt. 2010), and as such the species is projected to undergo a decline of 30-49% over the next 37 years (three generations).
