Blue-eared Lory Eos semilarvata


Justification of Red List Category
This species occurs in a small range. Its population is moderately small. As the species is captured for the cagebird trade, it is feared to be in decline, although the rate of decline has not been quantified. For these reasons it has been uplisted to Near Threatened.

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.

Distribution and population

The species is endemic to the island of Seram, Indonesia.


The species occurs in montane forest above 1,350 m, although it will occasionally range down to 800 m (Reeve et al. 2014, Collar and Kirwan 2018).


The species is being captured in low numbers for the cagebird trade (Sasaoka 2003). No forest was lost within the species's range between 2000 and 2012 (Tracewski et al. 2016); hence deforestation may not be a key threat.

Conservation actions

Conservation Actions Underway

CITES Appendix II. No targeted conservation actions are known for the species.

Conservation Actions Proposed

Survey the distribution range to quantify the population size. Monitor the population trend. Quantify the impact of hunting on the population size. Protect remaining habitat. Carry out education programmes to raise awareness for the species. Enforce existing legislation to prevent capture for trade.
