Population justification: Wetlands International (2022) place the total population in a band of c.14,500-17,000 individuals, roughly equating to 9,600-12,000 mature individuals. This may however be a considerable underestimate as the species is frequently observed across its large range (see eBird 2022). National population estimates include 250-999 mature individuals in French Guiana (UICN France et al. 2017), 2,500-9,999 mature individuals in Brazil (ICMBio 2018) and over 10,000 mature individuals in Ecuador (Freile et al. 2019). Tentatively, the total population is here placed in the band 20,000-49,999 mature individuals, though a comprehensive estimate is urgently required.

Trend justification: The overall population trend has not been investigated (see Wetlands International 2022) and may vary in different parts of the range. While it is reported to decline in Brazil, Argentina and Ecuador (ICMBio 2018, Freile et al. 2019, Martínez-Vilalta et al. 2020), it is stable in French Guiana (UICN France et al. 2017) and possibly increasing in Costa Rica (Martínez-Vilalta et al. 2020).
Tree cover within the range has been lost at a rate of 9% over the past three generations (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). The species is usually found near streams in humid forests (Martínez-Vilalta et al. 2020); it is consequently plausible that the population decline is roughly equivalent to the rate of tree cover loss. Tentatively, declines are here placed in the band 1-19% over three generations.
