Population justification: The global population size has not been quantified, but density descriptions range from uncommon to fairly common (Stotz et al. 1996, Schulenberg and Johnson 2020).
Based on the population density of a congener (L. amaurocephalus in Peru: 5 mature individuals/km²; Santini et al. 2018), and, to account for the species' apparently localised distribution (see eBird 2023) under the precautionary assumption that only 10% of the mapped range is occupied (i.e., 6,500 km²), the global population may number 32,500 mature individuals. To account for uncertainty, the population is here placed in the band 20,000-49,999 mature individuals.

Trend justification: The population trend has not been directly investigated, but due to the species' forest dependence, declines are suspected to be linked to forest cover loss.
Tree cover loss within the range is very low (2% over ten years; Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Population declines are therefore likely equally low and localised; they are here tentatively placed in the band 1-9% over ten years.
