Colorado State University and the Cornell Lab of Ornithology have an excellent tool for visualizing and forecasting bird migration called BirdCast. With BirdCast, you can see where migration is happening – lighter colors on the maps indicate stronger movements of birds. In the screenshot, note the vivid yellow and white in the southeastern United States on the night of April 30, 2022. This is where migration will be heavy for that date. Also note that in the Chicago area the colors are more subdued, indicating a less intense movement of birds. Follow the URL to start using it – BirdCast
