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. Should the species be found to be declining, it may warrant uplisting to a higher threat category.
RANGE DESCRIPTION
Anthracoceros albirostris is a widespread resident in northern South Asia, southern China, Indochina and western Indonesia.
DESCRIPTION
The global population size has not been quantified, but the species is reported to be the commonest Asian hornbill (del Hoyo et al. 2001).
Trend Justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats. |
