Taxonomic note

Celeus torquatus, C. occidentalis and C. tinnunculus (del Hoyo and Collar 2014) were previously lumped as C. torquatus following Sibley and Monroe (1990, 1993).

Population justification: The global population size has not been quantified, but the species is described as 'rare' (Stotz et al. 1996, O. Ottema in litt. 2020, A. Lees in litt. 2024). Given its extremely large range, the population is unlikely to be small.

Trend justification: The population trend has not been investigated, but declines in this forest dependent species are suspected on the basis of ongoing deforestation in large parts of the range. Over three generations (13.7 years), 6-8% of tree cover is lost within the range (Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). This value however does not account for the impacts of habitat fragmentation and degradation. Consequently, population declines may be larger than the rate of tree cover loss suggests, though the species is thought to be tolerant of disturbance to some extent (B. O'Shea in litt. 2024). Overall, population declines are here tentatively placed in the band 1-19% over three generations. Nevertheless, the population may locally be stable as vast areas of pristine habitat remain, e.g. in Suriname (O. Ottema in litt. 2020, see also Global Forest Watch 2023).
