Many animals can sense the earth’s magnetic field and use it to perform incredible feats of navigation; however, the sense itself remains relatively enigmatic. Over the past 16 years, studies have repeatedly demonstrated that magnetic orientation can be disrupted by an oscillating magnetic field in the Radio Frequency (RF) range of 1-10MHz. While the physical pathway behind this disturbance is still being studied, little attention has been paid to the natural “RF-ecology” of a migratory animal. In this talk we aim to briefly summarize the behavioral evidence for RF-disruption and compare the thresholds seen in these experimental studies to the natural “RF-landscape” seen by magnetic migrators. The RF-ecology of an animal is characterized here by examining the most dynamic, natural source of 1-10MHz RF noise: the sun. While the atmosphere generally becomes opaque at frequencies lower than 10MHz, many natural phenomena can alter the transparency range of the atmosphere, allowing frequencies as low as 1MHz to reach the surface. In addition, the emission spectra of the sun in the RF-range varies greatly over time, occasionally even over-powering man-made sources of RF-noise. We aim to provide a quantitative summary of the natural “RF-environment” migratory animals are likely to encounter and provide context for how these phenomena can affect magnetoreception research.
