The Grey-breasted Partridge is a small partridge with a striking black-and-white face. It lives in mountain forests of eastern Java and forages on the ground.
It is about 28 cm long and has a black-and-white pattern on the face.
Grey-breasted Partridges are short-legged birds of eastern Java’s forests. They have whitish foreheads, cheeks and throats, dark crowns and red legs. They walk and forage on the forest floor, groom their plumage and occur singly or with several birds together.
A 2025 paper reported photographs from Meru Betiri National Park. During 2017–2023, cameras were used across 111 two-by-two-kilometre grids to monitor Javan Leopards and their prey. Grey-breasted Partridges appeared among these records in 2018 and 2021.
Birds were documented in three areas, in forests at elevations of 446–960 metres. Images showed solitary birds and up to four together in a frame. Morning and afternoon photographs captured walking and foraging. Lower-elevation forest also formed part of the habitat documented for this bird.
IUCN Red List · Vulnerable · Global
The IUCN global assessment published in 2024 lists this species as Vulnerable with a decreasing trend. Forest loss and trapping for trade are principal threats. Proposed actions include expanding habitat protection, preventing trapping within protected areas, surveying populations, assessing trade and its effects on wild birds, and monitoring forest loss.
