How animals extract information from their surroundings to guide motor patterns is central to their survival. Here, we use echo-recording tags to show how wild hunting bats adjust their sensory strategies to their prey and natural environment. When searching, bats maximize the chances of detecting small prey by using large sensory volumes. During prey pursuit, they trade spatial for temporal information by reducing sensory volumes while increasing update rate and redundancy of their sensory scenes. These adjustments lead to very weak prey echoes that bats protect from interference by segregating prey sensory streams from the background using a combination of fast-acting sensory and motor strategies. Counterintuitively, these weak sensory scenes allow bats to be efficient hunters close to background clutter broadening the niches available to hunt for insects.

动物如何从周围环境中提取信息以指导运动模式对于它们的生存至关重要。在这里，我们使用回声记录标签来展示野生狩猎蝙蝠如何根据猎物和自然环境调整感官策略。在搜索时，蝙蝠通过使用大的感官体积来最大限度地发现小猎物的机会。在猎物追捕过程中，它们通过减少感官体积，同时提高感官场景的更新率和冗余度，以空间信息换取时间信息。这些调整会导致非常微弱的猎物回声，蝙蝠通过结合使用快速作用的感觉和运动策略将猎物感觉流与背景隔离开来保护它们免受干扰。违反直觉，
