【摘要】 <正> 蓝马鸡(Crossoptilon anritum Pallas)属珍贵的禽类。其羽毛艳丽,势态优美,已成动物园中名贵的观赏动物。 蓝马鸡属古北界青藏区的特产鸟类,仅分布于青海高原及其毗邻地区。1973—1974年作者在青海尖扎县冬果林区对蓝马鸡的生态进行了观察。该地位于黄河南岸,海拔2,700—3,800米,据1960—1970年黄南州气象站资料,年平均温度5.2—7.8℃,1月平均—6.0°——8.0℃,7月平均16°—19℃,无霜期139天左右,降雨集中在7、8、9三个月,一般为365—450毫米。更多还原

【Abstract】 This paper deals with ecological studies of the blueeated Pheasant (Crossoptilon auri-tum).We carried out field work on the blue-eared pheasant in 1973-1974 in Jianza Mian, Qinghai province at an altitude of 2700-3800m.The habitat of blue-eared pheasants is of four types:(1) Picea asperate forest; (2) mixed forest composed of Populus daviaiana, Betula sp. (3) Rhododendron capitatum shrubs; (4) alpine meadow. The seasonal variations of their numbers are presented in Tab. 1; those with respect to their food in Tab. 2.From the end of April to the beginning of May, the blueeared pheasant began to breed. Nests and eggs are described in the Chinese text.The growth of nestlings has been studied in each ten-day period (tab. 4) with weighing of the body and measurements of the body, beak, wing, tarsus and tail (fig. 3). Their growth rate may be calculated by:Wt or Lt =K/(1+eα-rt)The length-weight relationship may be expressed in the following fomula;W♂ = 0.007188L1.8173 W♀ = 0.007197L1.7969更多还原
