Description |
JUSTIFICATION
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). The population trend appears to be stable, and hence the species does not 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.
RANGE DESCRIPTION
Aethopyga siparaja has an extremely large range extending from the Himalayan foothills in India to Bangladesh, Bhutan, Myanmar, Nicobar islands, China, Laos, Cambodia, Vietnam, Thailand, Peninsular Malaysia, Indonesia (Sumatra and satellite islands, and Borneo and associated small islands, Java, Sulawesi, Kabaena, Muna and Butung) and the Philippines (Marinduque, Tablas, Sibuyan, Panay, Negros, Cebu).
DESCRIPTION
The global population size has not been quantified, but the species is described as usually common although rare to uncommon on Buton island (Cheke et al. 2001).
Trend Justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats. |
