Reeves’s pheasant aggregates into flocks of around six individuals (sometimes of ten or more in autumn and winter), dispersing into smaller groups in March with the onset of the breeding season. Male pheasants establish and advertise territories, attracting females by calling and ‘wing-whirring’ from March to early June. The male generally has a smaller home range size during the winter months, although the same ‘core’ area is used by Reeves’s pheasant throughout the year. Male pheasants also exhibit strong site fidelity, typically returning to the same territory each year. This pheasant is thought to be primarily monogamous, but occasionally polygamous. Females lay six to ten eggs into a nest on the ground, usually under bushes or in grass. Incubation lasts 24 to 25 days and is performed by the female alone.
