  "summary": "Lisowski et al. [1] recently proposed that the pigeon's magnetic compass resides in the liver and depends upon ferritin-containing macrophages operating through a superparamagnetic mechanism. Here we evaluate this hypothesis using behavioral, neurobiological, evolutionary, and biophysical evidence together with three original analyses. First, we present a quantitative reanalysis of the classic…",
