摘要:2004—2014年,于每年3月初—11月中旬采用线路调查方法监测尕海国际重要湿地黑颈鹤(Grus nigricollis)的数量。对郭茂滩天鹅湖边上的一对黑颈鹤采用定点观察法观察其繁殖行为。监测表明,每年有90只左右的黑颈鹤在尕海国际重要湿地中越夏繁殖;每年3月中旬开始陆续迁回,于11月上旬全部迁离。黑颈鹤的孵化日期约为33天,且有重复产卵孵化现象。 关键词 : 黑颈鹤, 数量, 迁徙, 繁殖, 保护管理 Abstract:We surveyed Black-necked Cranes (Grus nigricollis) at Gahai, Gansu Province from early March to mid-November every year from 2004-2014. During the count months each year, we observed breeding behavior of a pair of Black-necked Cranes nesting on the lake shore of Tianehu at Guomaotan. There were about 90 Black-necked Cranes breeding or summering at Gahai. The cranes begin to arrive at Gahai in mid-March and leave for their wintering ground by the end of November each year. The incubation period was ~33 days.Key words: Black-necked Crane Number Migration Breeding Conservation management 收稿日期: 2014-12-01 接受日期:PACS: Q959.7 Q958.1 作者简介: 李俊臻(1958—)男,甘肃临洮人,正高级工程师,从事自然保护工作。 |
