Taxonomic note
Goura scheepmakeri and G. sclaterii (del Hoyo and Collar 2014) were previously lumped as G. scheepmakeri following Sibley and Monroe (1990, 1993).

Population justification: There are no known population estimates for this poorly-known species, but its range contains more than 100,000 km² of suitable forest; thus, the population is unlikely to be small. eBird (2022) suggest that, at least locally, it may be fairly common.

Trend justification: Loss and degradation of lowland forest through large-scale selective logging and the development of oil palm plantations are suspected to be driving a population decline in this species. In the 20 years to 2021, forest cover in this species' range was reduced by c.8% (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein), equivalent to a rate of c.12% over three generations (28.5 years; Bird et al. 2020). As a strictly forest-dependent species, this is thought to be the minimum rate of population reduction, since the species is likely to be impacted too by degradation, fragmentation and additive impacts of hunting. Moreover, it appears to have some predilection for riverine and alluvial forests which are more accessible to both loggers and hunters. Consequently, the species is suspected of declining continuously at a rate of 15-29% over three generations.
