Ecology

These pheasants usually form groups of up to 10 individuals. They feed on the ground, foraging through the plant debris and grasses near woodland edges and among the rhododendron and juniper scrub. In areas where they are hunted, they may be elusive, retreating into the undergrowth or flying off downhill when scared, but where unmolested, can be quite bold. The birds are believed to be
