The Sumatran Hill Partridge has a mix of gray, brown, and chestnut plumage. It is found in hill and montane forest of central and northern Sumatra and is described as sedentary.
Its plumage combines gray, brown, and chestnut, with a white cheek and reddish skin around the eye.
Sumatran Partridges live in Sumatra’s forests. They have a blue-grey breast and a rounded white ear patch. Captive males are reported to build domed nests on the ground.
A paper released online in 2021 examined three eggs preserved in a Dutch museum. One captive pair in the Netherlands laid these infertile eggs in 1995. All were white, ovate to round-ovate, and about 4.1–4.2 centimetres long.
Labels dated laying to 22–24 April, indicating approximately one egg per day. Originally filed as a related species, the clutch was reidentified using photographs of the parents and archived correspondence. The eggs and their dates preserve a small account of one pair’s spring laying.
An extinction-risk assessment has not been added yet.
A conservation study published online in 2018 used historical records to infer possible loss of Sumatran Partridge outside protected areas. Maintaining protected forests and habitat in the surrounding landscape is relevant to conserving this island endemic.
