Justification of Red List category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (extent of occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Population justification
The global population is estimated to number 500,000-4,999,999 mature individuals (Partners in Flight 2019). The species is described as 'uncommon and patchily distributed' (Stotz et al. 1996).
Trend justification
The population is undergoing a large, significant decline (Partners in Flight 2019), which is thought to be caused by ongoing habitat destruction (del Hoyo et al. 2001). Tree cover within the range is lost at a rate of 7% over three generations (12 years; Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). Apart from humid forests the species is also found in secondary growth and plantations (Stelow 2020) and therefore, population declines are unlikely to exceed the rate of tree cover loss. Declines are here tentatively placed in the band 1-9% over three generations.
This species has a disjunct range, occurring in Central America to northwestern South America, in the Amazon basin and in the Atlantic forest.
The species inhabits humid forest as well as tall secondary growth and plantations (Stelow 2020).
The species is locally affected by the destruction of forested habitat within the range.
