摘要
关山林区的勺鸡（Ｐｕｃｒａｓｉａｍａｃｒｏｐｈａ）栖息于海拔１６００—２０００ｍ的密林中。繁殖期为４月中下旬至６月上旬。巢营于地面，呈碗形，外径２５０ｍｍ×２７０ｍｍ，内径２１０ｍｍ×２３０ｍｍ，深５２ｍｍ，多分布于林下阳坡上。每巢产卵６—９枚，平均卵重３６．２ｇ，卵径平均为３４．２ｍｍ×４７．２ｍｍ。卵色浅棕，具栗褐色斑点。勺鸡食性分析表明，勺鸡为杂食性，但以植物性食物为主。主要天敌有鹰、、蛇、狐、猫、鼬等。野外采卵进行孵化试验，孵化率８８．８９％，并对雏鸡的发育进行了观察。
In Guanshan forests, Gansu Province, the koklas pheasant (Pucrasia macrolopha) inhabits in places with an elevation of 1600-2000m. Its propagation period starting from mid or late April lasts till early June each year. its bowl-shaped nest is made on ground. The outer diameter of the nest is 250 × 270 mm and inner diameter 210 × 230 mm. The depth is 52 mm.Most of them are distributed mainly on sunny hillside. One nestful has usually 6-9 eggs. On the average, the size of each egg is 34.2 × 47.2 mm and weight 36.2 g, light brown in colour,the eggs bear lots of maroon spots. Analysis of its contains in crops proves that it is omnivorious, but the main food is plants. its natural enemies include hawk, buzzard, snake,fox, wild cat and weasel etc. Experiment of incubation showed that 88.89% of the eggs can be hatched. By artificial domestication, we observed and studied the development of young birds.
