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 suspected to number 500,000-4,999,999 mature individuals (Partners in Flight 2022). The species is described as 'fairly common' (Stotz et al. 1996).

Trend justification
The species is undergoing a significant decline, which is likely driven by habitat loss (del Hoyo et al. 2020, Partners in Flight 2022). In particular, populations in Central America are suffering from the loss and fragmentation of forests, with subsequent local extinctions (del Hoyo et al. 2020, Pollock et al. 2022).
Tree cover within the range is lost at a rate of 7-9% over ten years (Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Due to the species' strict dependence on undisturbed forests (del Hoyo et al. 2020), population declines may be steeper than the rate of habitat loss alone. They are here tentatively placed in the band 10-19% over three generations.

The species occurs from Honduras south to Ecuador.

It inhabits the understory of humid forest and mature secondary woodland (del Hoyo et al. 2020).

The species is threatened by the loss of its habitat through large-scale logging and agricultural expansion.

Conservation Actions Underway
The species occurs within several protected areas across its range. It is listed as Near Threatened at the national level in Ecuador (Freile et al. 2019).

Conservation Actions Proposed
Carefully monitor the population trend to detect any acceleration of the decline. Protect areas of suitable habitat within the range. Restore degraded habitat.
