This species has a very small population comprising very small subpopulations, which are declining owing to habitat loss and hunting. It therefore qualifies as Endangered.

|Range Description:||Pauxi pauxi occurs in west Venezuela and north Colombia. Nominate pauxi was formerly common from the Cordillera de la Costa west to the Cordillera de Mérida, Venezuela, and on the north-eastern slopes of the East Andes in Colombia (Norte de Santander, Boyacá and Arauca) and adjacent Venezuela (south-west Táchira). It is also known from three mountain ranges in Falcón, Venezuela, but may have recently disappeared from one (in Morrocoy National Park) (Silva 1999). It might once have occurred as far east as Monagas (Silva 1999). The population has declined considerably, and the species is now generally rare and occurs at low densities (Silva 1999, Wege and Long 1995). In Venezuela, there is a strong correlation between its current distribution and national parks (Silva 1999). Race gilliardi from the Sierra de Perijá on the Colombian-Venezuelan border is also believed to be declining. |

|Population:||Comments from P. Salaman (in litt. undated) and C. Sharpe (in litt. undated) indicate that the population fell below 2,500 individuals during 2007. It is thus placed in the band 1,000-2,499 mature individuals, equating to 1,500-3,749 individuals in total, rounded here to 1,500-4,000 individuals. Population density in Venezuela has been estimated to be 2 individuals / km2 in Aragua, 8 individuals / km2 in Yaracuy, and 5 individuals / km2 in Lara state. In Colombia 4.8 individuals / km2 were found in Tamá National Park.|
Trend Justification: A moderate and on-going population decline is suspected on the basis of rates of habitat loss and levels of hunting.
