Population justification: The population size of this species has not been directly quantified, but it is described as “common to locally abundant” (del Hoyo et al. 1997, Collar and Kirwan 2018). The median population density reported for Eos spp. is c.70-75 individuals per km² (Marsden and Royle 2015). Assuming that all suitable habitat is occupied, the population of this species would number 23,800-25,500 individuals, roughly equating to 15,870-17,000 mature individuals. As it is possible that this number is an overestimate, the species is here placed into the band 10,000-19,999 mature individuals. The species is likely to occur in just one subpopulation.

Trend justification: The species is tentatively suspected to be in decline owing to trapping for the cagebird trade. The species is seldom caught, albeit at only one site (Sasaoka 2003). At the moment there is no strong quantification of the extent to which capture for trade is driving declines in this species.
