Black Hornbill Anthracoceros malayanus
BirdLife is updating this factsheet for the 2016 Red List
Please email us with any relevant information

This species is largely dependent on lowland evergreen forest within a region experiencing high rates of deforestation. Although it may be more tolerant of secondary habitats than some other hornbill species, it is likely to be declining moderately rapidly, and is therefore considered Near Threatened as it almost qualifies for a threatened listing under criteria A2c+3c+4c.

Distribution and population
Anthracoceros malayanus is confined to the Sundaic lowlands of peninsular Thailand, Sabah, Sarawak and Peninsular Malaysia, Kalimantan and Sumatra (including the Lingga, Bangka, Belitung islands), Indonesia and Brunei (BirdLife International 2001). It is generally scarce or locally common in suitable habitat. Habitat loss has already driven it to the verge of extinction in Thailand.

Population justification
The population size of this species has not been quantified, but it has been described as locally common.

Trend justification
A moderately rapid decline is suspected to be occurring, in line with the widespread destruction and degradation of lowland forests throughout the species's range.

This species occurs in lowland primary evergreen forest, usually below 200 m. It is also found in selectively logged, gallery and swamp forest and tall secondary forest.

Forest destruction in the Sundaic lowlands of Indonesia has been extensive as a result of commercial and illegal logging, conversion to agriculture (particularly plantations) and increasing human population pressure. This species's dependence on plains-level habitats places it at high risk, especially in Sumatra and Malay Peninsula.

Conservation Actions Underway
CITES Appendix II. Conservation Actions Proposed
Monitor populations across the range to determine the magnitude of declines and rates of range contraction. Ensure the protection of remaining tracts of lowland evergreen forest throughout the Sundaic region.
