The Chestnut-bellied Hill Partridge is a ground-dwelling pheasant of Java’s mountain forests. A study in fragmented forest found it more often inside natural high-elevation forest than near the edges.
It is a small pheasant that spends much of its time walking on the ground.
Chestnut-bellied Hill Partridges live on the forest floor of Java. They often remain hidden in dense woodland but give distinctive calls. They also occur in groups in mountain-slope forests; their voices form part of the soundscape behind the trees.
A 1997 paper reported a survey filling a distribution gap in central Java. During March–September 1994, researchers primarily searching for Javan Hawk-eagles also recorded partridges. Learning their calls earlier on Mt Gede and Mt Pangrango helped them search central forests.
Almost all records were acoustic, but on 23 July the researchers saw six birds together at 1,730 metres on Mt Slamet. Evidence from several central forests showed that the species inhabited the area between its better-known western and eastern populations. Calls helped connect the known distribution.
An extinction-risk assessment has not been added yet.
A 2022 study combined long-term bird-market surveys with online sale records, finding this species offered outside its native range. Trader conversations and the birds’ skittish behaviour suggested wild origins. The author recommended targeting market hubs and other trade centres to make enforcement more effective.
