Population justification: The population size has not been quantified. Assuming that the species occurs at a similar density as congeners (C. cayana and C. cotinga in French Guiana: 2-4.5 individuals/km2; Santini et al. 2018), and, to account for its rarity, further assuming that only 10% of its mapped range is occupied, the population may number 1,880-4,230 individuals. This roughly equates to 1,250-2,820 mature individuals.
The subpopulation structure has not been investigated. Based on observational records (per eBird 2021) it is tentatively assumed that all individuals belong to the same subpopulation.
Trend justification: There are no new data on population trends. The species is inferred to be undergoing a continuing decline, which has led to its disappearing from previously occupied sites; there are no records from large parts of its range in Panama since 2013. Declines are thought to be caused by ongoing habitat loss (Snow and Sharpe 2020).
Over three generations (11.1 years; Bird et al. 2020), cover within the range is lost at a rate of 4% (Global Forest Watch 2021,using Hansen et al. [2013] data and methods disclosed therein). The species depends on a dense canopy layer (Snow and Sharpe 2020) and as such it is conceivable that population declines are steeper than the rate of forest loss. Tentatively, the population decline is here placed in the band 1-19% over three generations.
