Population justification: The species is described as very rare and local (G. Engblom in litt. 2003, Schulenberg et al. 2007). It may however be difficult to detect, as Doliornis cotingas have soft, easily overheard calls and tend to be relatively inactive. A survey in Carpish (Huánuco) found a density of 0.3 individuals/km2 (Rivas Mogollón 2019). Assuming that this density is representative for the entire range, the global population may number 3,570 individuals. This roughly equates to 2,380 mature individuals.

Trend justification: The population trend has not been assessed, but the species is suspected to be in decline due to the loss and degradation of elfin forests and páramo habitat through burning and overgrazing.
