Sunda Teal Anas gibberifrons


Justification of Red List Category
This newly-split teal is precautionarily suspected to be undergoing moderately rapid population declines owing to hunting pressure and habitat degradation. It has therefore been classified as Near Threatened, but better information may lead to a future reclassification.

Population justification
The population was estimated at 10,000-100,000 individuals in Wetlands International (2014).

Trend justification
There are no trend data, but the population is suspected to be undergoing moderately rapid declines as a result of to hunting pressure and habitat degradation.

Distribution and population

Anas gibberifrons occurs in Indonesia and East Timor, where it is known from SE Borneo (Kalimantan), S Sumatra, Java, Bali, Lombok, Sumbawa, Sumba, Flores, Lembata, Roti and Sulawesi (including Togian Is, Salayar, Muna, Buton and Sula Is), Timor and Wetar; perhaps also on Ambon, Kai and Tanimbar (Carboneras et al. 2013).


Uses a variety of wetlands and also found on rivers, with large concentrations sometimes recorded in mangrove swamps; has also been observed on sea (Carboneras et al. 2013).


Hunting and the conversion and degradation of river and mangrove habitat are presumably the primary threats.

Conservation actions

Conservation and research actions underway
No targeted actions are known.

Conservation and research actions proposed
Conduct further surveys to clarify its distribution and status. Instigate regular monitoring of selected key populations. Conduct long-term ecological studies to establish management requirements. Afford protected status to key sites. Promote strict enforcement of hunting regulations and minimise encroachment, disturbance and habitat degradation in all protected areas supporting populations.
