摘 要:2003年5月至2005年7月,在广西百色岑王老山自然保护区对再引入黑颈长尾雉Syrmaticus humiae的产卵、孵卵行为进行研究。遥测了4只雌性个体,对5窝正在孵化的雌鸟进行观察,结果表明:黑颈长尾雉有盖卵行为,平均窝卵数6.3个,产卵间隔1~2d,产下最后一枚卵前一天开始孵化,孵化期27d;巢温(37.7±1.16)℃;雌鸟单独孵化,每天都离巢,平均离巢时间(102±74)min,53.84%发生在早上,23.08%发生在中午,15.35%发生在下午(另有7.73%无法确定,故不计算在内);离巢的雌鸟有较固定的取食地。多元线性回归检验表明:天气状况与离巢时间长短有显著相关(t=3.717,P=0.001);卵质量与孵化时间有显著的负相关性(F=21.847,P=0.000)。From May 2003 to July 2005, the incubation behavior of Syrrnaticus humiae was studied in Cenwanlaoshan Nature Reserve,Guangxi Province. 4 female pheasants were radio-collared. And totally 5 nests were observed. The average clutch size of the pheasant is 6.3. The interval time of egg laying ranges from one to two days. The female begin to incubate one day before laying the last egg. Incubation time is 26-27 d. Temperature in nest is (37.7±1.16)℃. The female incubate alone and leave nest for feeding everyday. Leaving nest behavior happened in the morning, noon and afternoon is 53.84%, 23.08% and 15.35% respectively. The female has comparatively fixed feeling site. Linear return analysis shows the weather condition has significant effect on the length of feeding time (t= 3. 717, P= 0. 001). Mass of eggs significantly relates with the day of incubation (F=21. 847, P=0. 000). The positions of eggs in nest are changed frequently during the incubation period.
