From: Oscillating magnetic field disrupts magnetic orientation in Zebra finches, Taeniopygia guttata
Mean orientation scores after magnetic (A) and visually guided (B) orientation. Both experiments were performed in two magnetic conditions, a 90° shifted static magnetic field and in a shifted field with an additionally applied weak HF field. Reference values depicted as dashed lines: 0.5 for magnetic (axial) orientation, 0.25 for visual (directional) orientation. For details see text.
