This forecast uses current geomagnetic conditions (and some other stuff) to predict the appearance of vagrant birds during the spring and fall migration seasons. You can read more about the methodology in Tonelli et al, 2023. If you are interested, check out this recent paper on the same phenomenon, measured via radar.
