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 has not been quantified, but it is not believed to 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 size has not been quantified, but this species is described as uncommon to locally common in undisturbed forests (Short and Horne 2001).
Trend justification
The population trend has not been investigated, but the species' tolerance of a variety of forested, shrubby and secondary habitats near forest likely alleviate the impacts of deforestation (per Short and Horne 2001, Short and Kirwan 2020, eBird 2023). Within the range, 13% of tree cover has been lost over the past three generations (14.6 years); since 2017 this has been accelerating to a rate equivalent to 17% over three generations (Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Given that the species however never moves far away from forest, it is tentatively suspected that population declines are roughly equivalent to the rate of tree cover loss, and they are therefore here placed in the band 10-19% over three generations.
The species occurs in the Amazon Basin in Brazil south of the Amazon and east of the Madeira to northern Bolivia, with an isolated population in northern Ceará.
The species occurs in a variety of habitats, including moist and wet 'terra firme' forest, gallery forest, palm forest, deciduous forest, secondary and selectively cut forest, as well as thickets and 'várzea' (Short and Horne 2001, Short and Kirwan 2020). Its ecology is not well known.
The major threats to this species are the loss, degradation and fragmentation of its habitat through large-scale agricultural expansion and logging.
Conservation Actions Underway
None are known.
Conservation Actions Proposed
Quantify the population size. In view of accelerating deforestation rates, carefully monitor the population trend. Protect areas of suitable habitat within the range. Raise awareness for the species and its habitat.
