对于海鸟来说，飞行速度与风向/风速之间的关系被认为对于研究节能策略和觅食栖息地选择尤为重要。在这项研究中，我们使用高分辨率 GPS 数据记录仪检查了四种大鸬鹚 (Phalacrocorax carbo) 的地面速度和计算空气速度是否受到风力条件的影响。这些鸟在顺风中增加了地面飞行速度，在逆风中降低了地面飞行速度，并改变了与风分量相关的空气速度。不过，它们并没有根据风力情况改变觅食地点。它们可能会通过调整风速而不改变觅食地点来应对适度的风力条件。
In seabirds, the relationship between flight speed and wind direction/speed is thought to be particularly important for studying energy‐saving strategy and foraging habitat selection. In this study, we examined whether the ground and calculated air speeds of four great cormorants (Phalacrocorax carbo) were affected by wind conditions using high‐resolution GPS data loggers. The birds increased their ground flight speed in tailwinds, decreased it in headwinds, and changed their air speed in relation to wind components. However, they did not change their foraging sites according to the wind conditions. They were likely to respond to moderate wind conditions by adjusting their air speed without changing their foraging sites.
