Population justification: A field survey in 1993 on Yamdena Island, which represents c.55% of the species’s global range, revealed an estimated 220,000 ± 52,000 individuals (Jepsen et al. 2001). This roughly equates to 112,000-181,333 mature individuals, rounded here to 112,000-182,000 mature individuals.

Trend justification: The population is tentatively suspected to be in decline due to loss and degradation of its habitat and trapping for the cagebird trade, but the trend has not been estimated directly. Tracewski et al. (2016) measured the forest loss within the species’s range between 2000 and 2012 as c. 58 km2. This roughly equates to a rate of forest loss of 4.5% over three generations (21 years) for the species. Blue-streaked Lory seems to prefer secondary forest and plantations over primary forest (Collar and Boesman 2019), so forest loss alone may not drive a significant population decline. The species is caught for the cagebird trade, albeit at low numbers (Shepherd et al. 2004, Shepherd 2006, Chng et al. 2016). At the moment, there is no strong quantification of the extent to which capture for trade is driving declines in this species. Overall, it is currently not possible to estimate a population trend, although the species is tentatively considered to be undergoing a decline.
