【摘要】 2002年11月~2004年4月在四川省南充市区内对珠颈斑鸠(Streptopelia chinensis)繁殖生态和巢址选择进行了研究。结果表明:珠颈斑鸠3月初开始求偶交配,求偶行为复杂,有“婚飞”行为;雌雄参与筑巢,营巢期7~8 d。影响巢址选择的主要因素有6种:栖位与巢周隐蔽因子、巢下隐蔽因子、光照因子、人为活动因子、食物因子和营巢树因子;窝卵数2枚,雌雄轮流孵卵,孵卵期17~18 d,孵化率86.67%;雌雄均参与育雏,育雏期18~20 d,雏离巢率73.08%,繁殖生产力1.82,种群育雏高峰期为7月和8月中上旬。更多还原

【Abstract】 The breeding ecology and nest-site selection of the Spotted Doves(Streptopelia chinensis)was studied in northeastern Sichuan from November of 2002 to April of 2004.The results showed the Spotted Doves began breeding in March,and both male and female participated nest building.It took 7-8 days to finish the nest.Six factors were found to affect birds selecting their nest-sites.The female laid one egg every two or three days,and the clutch size was 2.Both female and male took part in incubation,it took 17 to 18 days for the eggs hatched.The incubation success was 86.67%.Nestlings were fed by parents for 18-20 days before they left nests.The nestling success was 73.08%.The peak period of brooding occurred in July and August.更多还原
