Population justification: Obtaining a solid population estimate is complicated by the fact that the population density varies drastically between sites, ranging from 0.04 individuals/ha to 6 individuals/ha (Renjifo et al. 2016). Based on count data from known sites, the overall population is estimated to number less than 2,500 mature individuals (Renjifo et al. 2016); it is here placed in the band 1,000-2,499 mature individuals.
The subpopulation structure has not been investigated, but observations away from regular sites indicates that the species may undertake local movements (Kroodsma and Brewer 2020). This suggests that, despite the somewhat localised occurrence, the population is not severely fragmented and that the number of subpopulations is low. Nevertheless, is it assumed that no subpopulation numbers more than 250 mature individuals (Renjifo et al. 2016).
Trend justification: Local declines have been observed over the past two decades, and the species has even disappeared from previously occupied sites (Renjifo et al. 2016 and references therein). Habitat loss has been below 10% over ten years, but the species is suffering from additional threats including nest parasitism and pollution (Renjifo et al. 2016). Consequently, the species is inferred to be undergoing a continuing decline, the rate of which is suspected at 30-49% over ten years (Renjifo et al. 2016).
