Migratory strategy of the great spotted cuckoo.

In the calculation of means only birds that completed migration were included, except for average travel speed which includes all birds apart from Green in spring migration since that bird died just a day after initiating migration. Cuckoo names correspond to the colors used in other figures. † indicates that bird was lost during migration. Brown and Dark Blue were lost during the stopover.在均值计算中，仅纳入完成迁徙的鸟类个体；平均飞行速度指标除外——春季迁徙的平均飞行速度纳入了所有个体，但名为"Green"的个体除外，该个体在启动迁徙仅1日后便死亡。各杜鹃个体的名称与其他图表中使用的颜色标识一一对应。符号"†"代表该个体在迁徙途中失联，其中Brown与Dark Blue个体在中途停歇地失联。
