摘要
2011~2013年,笔者通过利用人工蹲守、望远镜观察和数码相机拍摄方式,连续3 a在河北塞罕坝地区对红眉朱雀（Carpodacus pulcherrimus）繁殖习性进行了观察。观察发现,红眉朱雀为夏候鸟,居留期约5个月,每年4月末5月初迁来,9月下旬迁离。繁殖期为5月中旬至8月中旬。窝卵数为5±1枚,卵大小为（20.14±0.86）mm×（14.72±0.28）mm,卵重为（1.98±0.12）g（n=5）,孵卵期约13 d,在巢内育雏期约15 d。观察结果表明,塞罕坝地区特殊的地理区位和独有的气候特征,生境和植物种类的构成都为红眉朱雀提供了适宜的栖息地和食物,且人为干扰和天敌相对较少,适合红眉朱雀的栖息、繁殖和生存,且繁殖成功率较高。笔者据此认为管理部门和专家应进一步调查与研究塞罕坝地区的鸟类生物多样性及其特异性。
From 2011 to 2013, Is tudied breeding habits of beautiful rosefinch（ Carpodacus pul- cherrimus） at Saihanba National Nature Reserve by the naked eye, telescope and digital camera. Beautiful rosefinchis a summer resident, usually arriving at Saihanba in late April to eady May, and departing in late September. The breeding season lasted from mid-May to mid-August. Aver- age clutch size was 5 ± 1 eggs and eggs measured （20.14 ±0. 86） mm × （ 14.72 ±0. 28） mm, with an average fresh weight of 1.98 ±0. 12 g（ n =5）. The average incubation period was 13 days, the length of brooding was about 15 days. Beautiful rosefinch had higher reproductive suc- cess in Saihanba because the special geographical location and unique climate characteristics, suitable habitats and feeding sites, and plant structure. Human interference and natural enemies were relatively few. Reproduction and nestling survival was high. Bird biodiversity and population characteristics should be investigated and researched in Saihanba area by ornithologists and man- agers in future.
