摘要:

东方白鹳(Ciconia boyciana)主要在俄罗斯远东和中国东北繁殖, 在中国主要有两个越冬群体(长江越冬群体, 迁徙距离约2,600 km; 渤海湾越冬群体, 迁徙距离约1,500 km)。本文基于2016-2018年的卫星追踪数据(N = 14), 分析了渤海湾越冬群体幼鸟春季和秋季的迁徙策略和利用风的方式, 总结了850 mb压力下风速和风向对日迁徙飞行速度的影响。该群体春秋两季迁徙距离相似, 但春季的顺风条件(2.2 ± 6.3 m/s)显著优于秋季的逆风条件(-2.4 ± 4.1 m/s, P < 0.05), 这使得春季迁徙飞行速度(280.4 ± 62.0 km/d)显著快于秋季(185.5 ± 72.0 km/d, P < 0.05), 春季迁徙飞行时间(5.9 ± 2.5 d)显著短于秋季(10.3 ± 6.5 d, P < 0.05); 同时, 春季停歇时间(5.4 ± 9.7 d)短于秋季(17.8 ± 18.2 d, P = 0.05)。基于以上原因, 东方白鹳春季迁徙持续时间(11.2 ± 8.7 d)显著短于秋季(28.0 ± 21.2 d, P < 0.05)。渤海湾越冬群体幼鸟迁徙时, 春季利用顺风更快到达度夏地, 秋季逆风迁徙, 迁徙飞行速度慢, 迁徙飞行时间和停歇时间长。因此, 东方白鹳迁徙时虽然主要利用上升热气流翱翔, 但顺风也是其成功迁徙的有利因素。

Abstract

Aims: The Oriental Stork (Ciconia boyciana) primarily breeds in the Far East of Russia and Northeast China. There are two main migratory populations wintering in China, the Yangtze River wintering population, with a migration distance of about 2,600 km, and the Bohai Bay wintering population, with a migration distance of about 1,500 km. This study was conducted to obtain the characteristics of migration strategies and wind utilization of wintering populations in Bohai Bay during spring and autumn migration.

Methods: Based on the satellite tracking data of 14 juveniles from 2016 to 2018, we compared differences in their autumn and spring migration patterns and studied the effects of wind speed and direction at 850 mb on migration speed of the Bohai Bay wintering population.

Results: The migration distances in spring and autumn were similar, and the tailwind conditions in spring (2.2 ± 6.3 m/s) were significantly better than that in autumn (-2.4 ± 4.1 m/s, P < 0.05), leading to the daily flying speed in spring (280.4 ± 62.0 km/d) being significantly faster than that in autumn (185.5 ± 72.0 km/d, P < 0.05), and the flight duration of the spring migration (5.9 ± 2.9 d) was significantly shorter than that of the autumn migration (10.3 ± 6.5 d). Furthermore, the stopover time in spring (5.4 ± 9.7 d) was significantly shorter than that in autumn (17.8 ± 18.2 d, P = 0.05). Based on the above two points, the migration duration in spring (11.2 ± 8.7 d) was significantly shorter than that in autumn (28.0 ± 21.2 d, P < 0.05).

Conclusion: When migrating from/to Bohai Bay, the 14 juveniles used tailwinds to reach summering grounds faster in spring, and when they migrated headwinds in autumn, they flied slower and had longer flight and rest times. In conclusion, the Oriental Stork is a migratory soaring bird that primarily relies on thermal flow, while the tailwind also contributes to the migration success.
