中文摘要2006年10月29日—2007年5月19日,于云南省大山包黑颈鹤国家级自然保护区对黑颈鹤 (Grus nigricollis) 越冬种群的春秋季和春季日间迁徙行为进行研究。结果表明:越冬的黑颈鹤种群稳定期为947只,最高1 199只,90%个体的越冬时长为153天,最长为203天。越冬期间黑颈鹤种群数量呈现春秋迁徙期间的高峰期,说明大山包为黑颈鹤迁徙的中途停歇地和集散地。春季迁徙期间,黑颈鹤主要集成大于20只的群体(45.83%)于晴朗、轻风的天气开始迁徙,94.7%的个体于每日13:00 之前开始迁徙,10:00—11:00为每日的迁徙高峰时段。春季迁徙期,随温度上升每日迁徙的黑颈鹤比例上升(r=0.709),迁徙群体也呈增大趋势(r=1.000),并且起始迁徙时间显著提前(r= -1.000)。随着日期的推移黑颈鹤每日迁徙的比例显著升高(r=0.854,n=6,P=0.031),表明黑颈鹤迁徙具有自我催促机制,而迁徙过程受到强风和多云天气的负影响。

英文摘要Seasonal and daily migration behavior of Black-necked Cranes Grus nigricollis was observed from October 9, 2006 to May 19, 2007 at Dashanbao National Nature Reserve, NE Yunnan, China. An average of 947 Black-necked Cranes were recorded from November 19, 2006 to March 17, 2007 at the reserve, while a peak number of 1,199 occurred after March 17 during the spring migration period. There were 203 days from the first arrival to the last departure of the Black-necked Cranes, while 90% individuals left for their breeding ground after 153 days. Three numerical peaks of the cranes were detected during autumn and spring migration periods, indicating Dashanbao also served as a staging and stopover site for this species during their migration. The cranes started their spring migration on sunny days with a light breeze, and migration flock sizes were usually larger than 20 individuals. 94.7% of the migrating cranes took off before 13:00, mostly between 10:00 and 11:00. The timing of departure was highly correlated with air temperature at departure initiation-cranes departed earlier with higher temperatures(r= -1.000). When the air temperature was higher, a higher proportion of cranes and bigger flock sizes of the cranes departed. The proportion of the birds departing was mainly correlated with date and weather conditions, indicating that endogenous urging mechanism plays an important role in bird migration.
