Justification of Red List category
This species qualifies as Near Threatened because it has a very small population, which is suspected to decline as a result of continuing degradation and loss of its habitat.

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.

Doliornis sclateri occurs on the east slope of the Andes in north and central Peru, with records from San Martín, Huánuco, Pasco and Junín. Its known distribution is localised, though it may be overlooked and also occur in suitable intervening areas.

It inhabits the páramo/cloud-forest ecotone at 2,600-3,800 m, preferring low trees with dense canopy (Schulenberg et al. 2007, Schulenberg and Kirwan 2020). It seems to favour complex treeline habitat, which is getting increasingly rare and is now found mostly in small, fragmented patches. It is mainly frugivorous, but also takes invertebrates (Snow 1982, Schulenberg and Kirwan 2020). Otherwise, its ecology remains largely unknown.

The páramo/cloud-forest ecotone habitat favoured by this species is being reduced and degraded owing to the use of fire to maintain pastureland and overgrazing by livestock (SERFOR 2018, Schulenberg and Kirwan 2020).

Conservation Actions Underway
It occurs in Río Abiseo National Park.

Conservation Actions Proposed
Conduct surveys to locate additional populations and clarify the distribution range. Census the population and quantify the population trend. Research the species' ecology. Quantify the impact of threats on the population size. Monitor the population trend. Monitor rates of habitat loss. Protect areas of suitable habitat within the range. Prevent overgrazing and regulate the use of fire. Raise awareness for the species and its habitat.

21.5 cm. Large, dark cotinga. Males have black crown and nape (with partially concealed red crests), and are dark brown above and paler brown below, with rufous undertail coverts and grey throat and sides of head and neck. Female similar, but lacks black crown. Similar spp. The only high elevation cotinga with rufous undertail coverts and pale irides, features which separate it from D. remseni.
