Migratory prey experience spatially variable predation across their life cycle. They face unique challenges in navigating this predation landscape, which affects their perception of risk, antipredator responses, and resulting mortality. Variable and unfamiliar predator cues during migration can limit accurate perception of risk and migrants often rely on social information and learning to compensate. The energetic demands of migration constrain antipredator responses, often through context-dependent patterns. While migration can increase mortality, migrants employ diverse strategies to balance risks and rewards, including life history and antipredator responses. Humans interact frequently with migratory prey across space and alter both mortality risk and antipredator responses, which can scale up to affect migratory populations and should be considered in conservation and management.

迁徙猎物在其整个生命周期中都会经历空间变化的捕食。他们在驾驭这种捕食景观时面临着独特的挑战，这会影响他们对风险的感知、反捕食者的反应以及由此产生的死亡率。迁徙期间可变的和不熟悉的捕食者线索会限制对风险的准确感知，而且迁徙者通常依赖社会信息和学习来补偿。迁徙的能量需求限制了反捕食者的反应，通常是通过依赖于环境的模式。虽然移民会增加死亡率，但移民采用不同的策略来平衡风险和回报，包括生活史和反捕食者的反应。人类经常与太空中的迁徙猎物互动，并改变死亡风险和反捕食者的反应，
