Resident species

Comportamiento

They flock in groups of about 4–9, usually consisting of two parents and their latest offspring or sometimes two families. They feed on seeds, small shells, and insects found in leaves on the forest floor. When disturbed by humans, they quickly scatter into the underbrush. Captive male bar-backed partridges attract a mate by exposing the red feathers around their throat and calling. They breed around May to June, and their 37 by 28 mm (1.5 by 1.1 in) eggs are usually laid in a hole covered with bamboo and grass.
