Population justification: The population size has not been quantified, but the species is generally infrequently observed, described as rare and mostly seen in small numbers (Reid 1989, del Hoyo et al. 1994, Haenn et al. 2014, Holste et al. 2020, J. Barrio in litt. 2023).

Trend justification: There is no data on the population trend (Santangeli et al. 2022). However, local declines have been reported in parts of the range, including in Mexico, Honduras, Colombia, northern Ecuador and Paraguay (R. Clay in litt. 2023, P. Monar in litt. 2023, J. F. Restrepo Mesa in litt. 2023, C. Ruiz-Guerra in litt. 2023, J. Van Dort in litt. 2023). The drivers of the decline are somewhat unclear, but loss and degradation of habitat are likely contributing factors (per Holste et al. 2020). The population trend however appears to vary, as the species is reported to be stable in Brazil and Bolivia (B. Hennessey in litt. 2023, E. R. Luiz in litt. 2023, B. Phalan in litt. 2023, R. Subirá in litt. 2023).
Considering that the majority of the global population is found in Brazil (per Fink et al. 2022, Monroy-Ojeda 2022) it is likely that the declines detected in the periphery of the range are to a certain extent balanced out by the presumed stability in its core. Nevertheless, as there is strong evidence that population reductions are taking place in parts of the range, it is assumed that the overall population is undergoing a slow decline.
