摘　　要：本文报道了白腹锦鸡Chrysolophus amherstiae在滇中高原地区的典型栖息地,繁殖期的种群密度,占区行为,求偶炫耀,巢与卵的特征,雌鸟孵卵行为及雏鸟的食性。This paper presents results of our studies on the breeding ecology of Lady Amherst's Pheasant (Chrysolophus amherstiae) in Gulu (Eastern longitude 102°30'; Northern latitude 25°20') , western mountains of Kunming, middle part of Yunnan Province. Surveys in sample plots shows that the density of breeding male pheasants in secondary forest of pine ( Pinus armandii ) is the lowest ( See table 1 ). The density of breeding males in deciduous secondary forest and in bush and coniferous-evergreen broadleaf secondary forest is not different. The reason relative to the difference is secondary forest of pine with a few of plant species and short age of food. Meanwhile, concealments are poor in secondary forests of pine, so males arc easily found by hunters and killed. The density of breeding female pheasants in secondary forest of pine is still lower. The reasonis is as indicated above. But the density of females in sample plot no. It is not different from the density of secondary forest of pine. The cause is that local people often fell trees and herd goals and cattle in sample plot no. When we were surveying population of females. Perhaps, the economic activties disturbed some females to move other forest. The density does not include males which do not occupy territory and females which do not breed, so, it is only the density of breeding pheasants. Cocks begin to take territory in late of March. Acceding to observation of territory on 9 cocks, each cock's average territory is 0.076 KM2 in the breeding season. There are 2 - 3 hens in each cock's territory. It is polygynous. Cock display takes place on a small open area in forest. It is typical lateral display and is similar to Golden Pheasant ( Chrysolophus pictus). Females begin laying eggs in the middle of April. Six nests were found. All of which were built on land in thickets or under withered branches. The nests are very simple, a round shallow pit with dead leave and a few of feathers, the size of the nests and eggs in each cl
