From: Radar quantifies migrant concentration and Dawn reorientation at a Great Lakes shoreline
Example Trackplot images from the horizontal scanning radar that depict the direction of target movement during paired morning hours from shoreline and inland locations during trials A, B, and C. The color of each track indicates flight direction according to the color wheel in the upper right corner: dark blue for north, red for south, magenta for west, and green for east. The coastline is highlighted in white on the underlay of shoreline images. Lake Michigan is to the left of the white line. Targets returning to shore are light blue and green tracks on the left side of the shoreline images
