Population justification: This species is described as 'uncommon' (Stotz et al. 1996). 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 (c.1,070,000 km2), and assuming that the range is between 10.3% and 11.28% occupied, the population is estimated to fall within the band 110,000-241,000 individuals, roughly equating to 70,000 – 160,000 mature individuals. Therefore, the population is placed here in the band 50,000 - 200,000 mature individuals.
Trend justification:
An analysis of forest loss from 2000 to 2012 found that forest within the species's range was lost at a rate equivalent to 10% over three generation lengths (Tracewski et al. 2016). The species is also threatened by hunting, and so is suspected to be declining at 15-25% over three generation lengths.
