![maps and charts - Predicted responses and results for the CMF treatment. (a) Map illustrating Eurasian reed warblers’ natural migratory direction (black arrow) from the study site (Illmitz, Austria; black dot) under natural magnetic field (NMF) conditions during autumn and the predicted migratory directions from the virtual displacement site (Neftekamsk, Russia; white dot) under changed magnetic field (CMF) conditions (magnetic inclination and magnetic declination changed), if birds do (white arrow) or do not (black arrow) perceive these magnetic values as a translocation and respond by re-orienting towards the site of capture or the migratory corridor of the population (see [other figure] for map colour key). Dashed isolines give values naturally occurring near the virtual displacement site (see Methods for exact values). (b) Orientation of birds tested under NMF conditions of the study site (left) and under CMF conditions (right). Black dots indicate the mean direction of each individual bird tested; arrows show the second-order mean directions and their vector lengths; the inner and outer dashed circles indicate the threshold needed for significance by the Rayleigh test (p < 0.05 and p < 0.01, respectively); solid lines either side of mean vectors show the 95% confidence intervals. (c) Results from our previous virtual magnetic displacements. Both the study site and the virtual displacement site are the same as in the current study.](https://files.mastodon.social/cache/media_attachments/files/113/511/119/194/159/698/original/63a11483253461cb.jpg)
