迁徙的最后阶段,即动物终止迁徙运动并向更定居的状态过渡的阶段,仍然是迁徙中最不为人所知的阶段。每年返回同一地点的移民可能使用与定位特定目的地相关的机制,而地点保真度低的移民,如游牧移民,可能依赖当地环境线索来决定何时停止迁移。通过对圈养鸟类的实验,我们测试了同种鸟类的存在是否会影响迁徙的终止,这表明了游牧迁徙(松siskin,Spinus pinus)的行为和生理变化。我们将候鸟与非候鸟配对,或者让候鸟和非候鸟不配对。配对候鸟的夜间活动在配对后立即明显减少,两周后活动水平仍然较低,能量储备和飞行肌肉大小也明显下降。相比之下,没有配对的候鸟保持了高水平的活动和能量储备。这些结果为社会环境在迁移终止决策中的作用提供了证据。社会暗示可能对游牧移民特别有用,例如松siskins,有助于在高质量但不熟悉的栖息地安顿下来。
The final stage of migration, when animals terminate migratory movements and transition to a more sedentary state, remains the least understood phase of migration. Whereas migrants that return to the same locations each year may use mechanisms associated with locating a specific destination, migrants with low site fidelity, such as nomadic migrants, may rely on local environmental cues to determine when to cease migratory movements. Using an experiment with captive birds, we tested whether the presence of a conspecific influences the termination of migration, indicated by changes in behaviour and physiology, in a nomadic migrant (the pine siskin,Spinus pinus). We paired migratory birds with a non-migratory individual or left migratory and non-migratory individuals unpaired. Migratory paired birds had a significant decline in nocturnal activity immediately after pairing and activity levels remained lower two weeks later, with significant declines in energetic reserves and flight muscle size also observed. By contrast, migratory unpaired birds maintained high levels of activity and energetic reserves. These results provide evidence for a role of the social environment in migratory termination decisions. Social cues may be particularly useful in nomadic migrants, such as pine siskins, to facilitate settling in high quality, but unfamiliar, habitats.
