Structure of Hill-partridge
The males of Hill-partridge, the species have ornate patterns and markings, a combination of an orange crown and face set against a black head and streaked throat.

The nest is a ball of whatever manageable materials are within a few feet of the nest site with a lined shallow scrape at the centre to form the cup of the nest. In captivity the structure is generally unstable unless supported, typically within low-growing vegetation or roots.
