Population justification: Partners in Flight suspect the total population to number 5,000,000-49,999,999 mature individuals, based on information from 2016 (Partners in Flight 2020). The nominate subspecies major is abundant where forest is intact (Restall et al. 2006). In Suriname, it is described as common throughout the inland primary forests (O. Ottema in litt. 2020).

Trend justification: Partners in flight suspect that the population size is moderately declining (Partners in Flight 2020). The species is inferred to have a continuing decline in population size, based on remote-sensed data on tree cover from 2000 onwards that indicates ongoing tree cover loss within the species's range (Tracewski et al. 2016, Global Forest Watch 2020).

An analysis of remote sensing data on tree cover loss from 2000-2012 estimated that tree cover was lost at a rate equivalent to 5% over three generations (20.94 years; Tracewski et al. 2016). Based on tree cover loss data from 2001-2019 from Global Forest Watch, an estimated 8% of tree cover with at least 30% canopy cover was lost within the species's range over the past three generations (20.94 years; Global Forest Watch 2020). Based on tree cover loss data from 2016-2019, during which c.2% of tree cover within the species's range was lost (Global Forest Watch 2020), c.12% of tree cover is projected to be lost within the species's range over the next three generations. The species is highly forest-dependent, so its population size is suspected to be declining in line with tree cover loss. It is also susceptible to hunting, which is assumed to contribute an additional population decline of up to 5% over three generations. Therefore, the species is suspected to have undergone a population reduction of 8-13% over the past three generations, and to undergo a population reduction of 12-17% over the next three generations.
