The breast and back are mottled in black, chestnut, and cream colours, with black spots on the flanks and above. The partridge's face and throat have rich

Behaviour

Like many Galliform bird species, the birds prefer hiding to flight, but will readily flush if approached, startling pursuers with loud wingbeats. Within the forest, bamboo partridge are known to fly uphill, weaving through timber. This is an unusual behaviour, recorded only in the unrelated

Aviculture

Chinese bamboo partridges have been part of Chinese aviculture for centuries. In captivity, these tiny birds are pugnacious and care should be taken as to what other terrestrial species should be kept in mixed-species aviaries. They are compatible with crestless firebacks and eared pheasants but not with
