中文摘要:
      2010年4~8月间在甘肃安西极旱荒漠国家级自然保护区,对荒漠伯劳(Lanius isabellinus isabellinus)的繁殖生态进行了研究。荒漠伯劳的繁殖时间为4月底至8月初,每巢产卵3~6枚,平均窝卵数4.67±0.57(n=21),平均卵体积(3.14±0.32)cm3(n=95),平均卵鲜重(3.48±0.20)g(n=20)。雌鸟产首枚卵后即开始孵卵,雄鸟负责情饲及警戒。温度自动记录仪测量平均孵化温度为(38.19±0.77)℃。孵卵期15~16 d。荒漠伯劳雏鸟留巢期12~15 d,幼鸟离巢后亲鸟继续饲喂幼鸟,整个育雏期最长达31 d。孵化率82.50%(n=80),卵成功率为46.94%,离巢率62.96%(n=81),巢成功率58.62%。被大杜鹃(Cuculus canorus)寄生的巢占10.34%(n=29)。
英文摘要:
      From April to August in 2010,we studied the reproductive ecology of Lanius isabellinus isabellinus in An’xin Extra-arid Desert National Nature Reserve. Breeding season lasts from the end of April to Early August. There were 3-6 pieces of eggs per nest, the average clutch size of L. isabellinus was 4.67±0.57(n=21)eggs and the egg volume was 3.14±0.32 cm3 (n=95), average fresh eggs mass was 3.48±0.20 g (n=20). After laid the first egg, the female birds began incubation, and males were responsible for courtship feeding and guarding. Measured by automatic temperature recorder, the average incubation temperature was 38.19±0.77℃, the duration of incubation was 15-16 days. Nestling period lasted 12-15 days, after nestlings left, the parents birds continued to feed the baby birds, the whole breeding period was up to 31 days at most. Hatching success was 82.50%(n=80), nesting success was 46.94%, fledging success was 62.96%(n=81), nest success rate was 58.62%. During the entire breeding season, three nests of L. isabellinus were found to be parasitized by Cuculus canorus, which accounting for 10.34% of the total nests.
