Population justification: Based on the recorded population densities of closely-related species (Tinamus tao: 1 individual/km² and Crypturellus soui: 2 individuals/km² in Peru (Terborgh et al. 1990)) and the area of mapped range (28,700 km²), and assuming that the range is between 10.3% and 11.28% occupied, the population is estimated to fall within the band 2,956 - 6,475 individuals, roughly equating to 1,971 – 4,317 mature individuals, rounded here to 1,900 – 4,400 mature individuals.

Trend justification: The species's population is suspected to be undergoing a rapid decline, based in part on recent observations regarding the level of hunting pressure in some areas (Gastañaga et al. 2007, R. MacLeod and M. Gastañaga in litt. 2011), in addition to ongoing habitat loss and degradation.
