Population justification: The population in the El Paujíl Bird Reserve was estimated a maximum of 254 individuals in 2009, whilst surrounding area (including the reserve) may hold up to 509 individuals. There are several populations elsewhere, but these are thought to be severely declining or already locally extinct (D. Caro in litt. 2010), hence a populations band of 250-999 individuals is appropriate. This equates to 167-666 mature individuals, rounded here to 150-700 mature individuals.

Trend justification: This species has declined dramatically owing to habitat loss and hunting pressure. Given that protection is inadequate throughout the majority of its restricted range (even within protected areas) very rapid declines are suspected to be ongoing.
