The Pigeon Compass: How the Inner Ear Reads Earth's Magnetic Field

A deep dive into magnetoreception, tracing the breakthrough that ties magnetic sensing to the pigeon's vestibular system. We explore the 19th‑century Vigier idea, how rapid head movements could induce detectable nanovolt signals in the semicircular canals, and how specialized hair cells translate those signals into neural pathways guiding long-distance navigation. We’ll compare this inner-ear mechanism with light‑dependent theories and discuss why birds may rely on multiple, redundant navigation systems.Note:  This podcast was AI-generated, and sometimes AI can make mistakes.  Please double-check any critical information.Sponsored by Embersilk LLC
