LC
Oriental Dollarbird Eurystomus orientalis



Justification

Justification of Red List Category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The global population size has not been quantified, but the species is reported to be frequent to common throughout most of its range (del Hoyo et al. 2001), while national population estimates include: c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in China; < c.1,000 individuals on migration in Taiwan; c.100-10,000 breeding pairs and c.50-10,000 individuals on migration in Korea; < c.100,000 breeding pairs and < c.1,000 individuals on migration in Japan and c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Russia (Brazil 2009).

Trend justification
The population is suspected to be in decline locally owing to ongoing habitat destruction (del Hoyo et al. 2001).
