Population justification: The population size has not been directly quantified. However, population densities are known for 24 species in the family of Cotingidae, all ranging from 0.25 to 1 individual per km2 (Santini et al. 2018). Assuming that this species occurs at the same density throughout its known breeding range, the population is preliminarily estimated at roughly 5,400-21,000 individuals, which equates to 3,600-14,000 mature individuals. In Costa Rica and Panama, the species is described as 'fairly common' (Ridgely and Gwynne 1989; Angehr and Dean 2010; Garrigues and Dean 2014).
Three-wattled Bellbird is thought to form four subpopulations (Brant et al. 2020). Under the preliminary assumption that these are of roughly equal size, each subpopulation may number 1,350-3,500 mature individuals.
Trend justification: The species is undergoing a large, significant decline (Partners in Flight 2019). The rate of decline is thought to exceed 50% between 1970 and 2017 (Partners in Flight 2019, see also Panjabi et al. 2019). This equates to a decline of at least 20% over the last three generations (18.3 years) and is thus here placed in the band 20-29% over three generations.
