| 摘 要： | 山斑鸠在拉萨地区是一种夏候鸟,每年的4月初开始迁入拉萨。它们在人工林、沙棘林和高山灌丛营巢和夜宿,以林间空地、农田、河滩以及荒地为主要的取食地。巢置于较高的树木或郁闭度大的树上,4月底开始筑巢,营巢期一般为6-8d左右;巢平均大小为21.85(16-27)cm×3.07(2-4)cm,离地高为350(200-527)cm,巢重为54.3g(52-64)。5月初产卵,日产一枚,平均窝卵数为2枚(21巢),卵平均重量为10.36g(8.5-12),平均大小为33.27(27-37)×22.6(23-26)mm。孵化期为16-17d,13巢的统计平均孵化率仅为60%。育雏期为16-18d,离巢率为56%。雌雄鸟均参加孵卵和育雏。人为干扰和不良的天气是影响巢成功率的主要因子。
