Description

Lady Amherst Pheasants expose a strong sexual dimorphism, which means that males and females differ in their appearance.
Adult males are colorful, with a green, blue, white and yellow body plumage. The head is decorated with a red cap, which can be elongated during displays.  The iris is light yellow and the bill color ranges between greyish, bluish and greenish. Typical of the Lady Amherst Pheasant is the white collar which reaches from the crown to the neck. The collar feathers are bright white but have a rounded black ending. Also the feathers on the back show black hemmed patterns as well as almost all tail feathers. The underparts a mostly white. The tail is compared to the length of the body quite long and measure up to approximately two thirds of the total body-length. The upper feathers are white, lower ones tend to be more greyish and there are some orange feathers to find.

The plumage of the female Lady Amherst Pheasant is more simple and resembles to other female pheasants as the Golden Pheasant. The feathers are brown and the upper parts and becoming lighter in the underparts. The black stripes are showier than the male ones. Male birds alike, the eye parts are unfeathered.

Range and habitat

Behavior 

These birds have elaborate mating rituals. Males will dance and spread the ruff of feathers on their heads. Females select the strongest and most brightly colored males.

They have a variety of vocalizations: advertising, contact, alarm, and contentment.

Diet 

They feed on the ground on grain, leaves and invertebrates, but roost in trees at night.

Reproduction 

Breeding season varies with climate, but usually begins in May. The mating ritual is among the most elaborate of all the pheasants. It may take place over several hours, with the hen choosing the strongest and most brightly colored cock from the group. The posturing and dance of the male occurs within an area in a clearing on the forest floor. The male spreads a large ruff of feathers on the head like a fan during the courtship display. A small wattle under the eye is expanded to cover the lower part of the cheek. Nests are concealed in dense undergrowth where they are difficult to be seen. The clutch usually consists of 5-12 eggs that hatch in about 22 days. During a season, 30-40 eggs in various clutches may be laid.  They will readily hybridize (crossbreed) with the Golden Pheasant, producing fertile offspring.
