In dusk\u2019s still throat,
\nshadow-singers carve
\ntheir path
\nthrough air\u2019s thick weave \u2013
\nsong-lines stretched
\nthrough crumbling walls
\nof root and stone.
\nNight\u2019s shroud softens,
\nfilled with pulse-waves
\nto trace the bones of earth \u2013
\nghosting familiar shapes
\nthrough silent fields.
\nThey feel the far-off call,
\na drift of land-breath
\nbrushed through wing’s edge \u2013
\ndistance a tender echo,
\nwaiting to be heard.<\/p>\n

This poem is inspired by recent research<\/a>, which has found that bats use an acoustic cognitive map for navigation.<\/p>\n

Scientists have long been fascinated by how animals navigate their environments, especially under challenging conditions. Bats are particularly intriguing due to their use of echolocation \u2013 emitting sound waves and interpreting the returning echoes \u2013 to detect obstacles and move through darkness. While it is well established that echolocation helps bats in close-range orientation, it is less clear whether they use this sense to navigate over long distances.<\/p>\n

This study examines that question by tracking wild Kuhl\u2019s pipistrelle bats (a bat species weighing only 6 grams) after relocating them from their home area. Researchers manipulated the bats\u2019 access to senses like vision, magnetic fields, and smell, then monitored their movements with an advanced GPS system. Findings reveal that bats can indeed rely on echolocation to navigate several kilometres. A large-scale model further demonstrates how bats create mental maps based on surrounding sounds, enabling them to navigate through unfamiliar terrain. Additionally, the study shows that combining echolocation with vision improves their navigational accuracy, underscoring the adaptability of bat sensory systems.<\/p>\n
