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 navigat...
