chestnut-headed partridge Arborophila cambodiana

Shy and secretive small gamebird restricted to the Cardamom range of Cambodia and far eastern Thailand. Richly patterned, with a bright orange breast, black-and-white scaled sides, and black-barred brown upperparts. Cambodian birds also have a bright orange head and neck. Forages in pairs on the forest floor, duetting loudly to one another in the morning and early afternoon, giving loud ascending couplets followed by a series of chipping notes from one of the pair.
