摘要
1986～1987年,我们在乌梁素海研究了草鷺的繁殖生态及其幼雏的生长发育规律。该鸟三月末迁来,不久就在蒲苇地深处造巢,巢呈盘状,巢材为苇茎和苇叶,内垫苇穗等。巢由雌雄性共同编造。窝卵数3～5枚,卵为卵圆形,天蓝色。卵子均测量:卵径59.1×40.7mm;重51.3g。雌雄亲鸟共同承担孵化任务,孵化期约27～28天,孵化率约73％。草鹭雏鸟早期发育呈现一定的规律,并可以数学公式进行模拟、
The Purple Heron (Ardea parpurea) is one of the more common summer residents in Wuliangsuhai region of Nei Mongol. Studies on their breeding ecology had been carried out during the years 1986～1987. Results obtained may be summarized as follows. The Purple Heron appear on Wuliangsuhai by the end of march. Their nests are found in reed swamp. Nest-building is carried out by both parents, usually taking about 7～10 days. They are disk-shaped, and are mostly made of the reed-stems, reed-leaves, and cattail leaves, internally lined with the ears of reed. The number of eggs of one clutch is 3~5. The eggs are oval in shape and blue incolour. The eggs average 51.3(46.5～54)g in weight and 59.1(53～64)×40.7(40～42.5)mm in size. Both the male and female parents share in incubation. Incubation of eggs lasts for about 27～28 days. The percentage of hatching averages (10 clutches) 73%. This paper also deals with the growing law of nestlings, the early development of nestling accords with Y=27.6121x^(1.0621).
