Population justification: This duck has been described as 'often scarce but locally fairly common' (Coates 1985). It is 'rare to uncommon' in accessible areas where hunting may have reduced the population density, but can be easily found in some areas with moderate disturbance, and there are large areas of inaccessible habitat across its range (J. Bergmark in litt. 2021). It is uncommon below 600 m and is most common at the highest altitudes (Coates 1985, Beehler et al. 1986, Callaghan and Green 1993, J. Hornbuckle in litt 1999, Beehler and Pratt 2016). The population size and subpopulation structure are unknown.

Trend justification: The population trend is unknown.
