Population justification: This species is generally uncommon to locally common and is known from a fairly small number of localities (Kirwan et al. 2004, del Hoyo et al. 2020), although its behaviour renders it inconspicuous in denser forests, so it may be more common than records suggest (Kirwan et al. 2004). The species was found to be common during surveys at Jequitaí, Minas Gerais (Vasconcelos and D'Angelo Neto 2018), but the species has not been detected with such frequency elsewhere. The population size is unknown.

Trend justification: Remote sensing data indicate that approximately 8% of tree cover was lost from the species's range over the past decade (Global Forest Watch 2021). Although the species is not found solely in forest, the population size is tentatively inferred to be declining as forest within its range is lost and degraded. Additionally, a model projected that the species may lose 53-66% of its 1990 range by 2070 as a result of climate change (Da Silva 2017), which may equate to a loss of 9-13% over ten years, assuming exponential decline. The species's population size is therefore suspected to be declining at a rate of less than 20% per decade.
