Are you anxiously awaiting the arrival of spring migrants? You can track migration using Birdcast or Bird Migration Explorer.
Birdcast models use the Global Forecasting System to predict suitable conditions for migration. Bird migration forecasts show predicted nocturnal migration 3 hours after local sunset and are updated every 6 hours. These forecasts come from models trained on the last 23 years of bird movements in the atmosphere as detected by the US NEXRAD weather surveillance radar network. Colorado State University and the Cornell Lab of Ornithology currently produce these forecasts.
Audubon has recently launched Bird Migration Explorer, that tracks 458 bird species that regularly breed in the United States and Canada and use areas in Latin America and the Caribbean during other times of the year. You can take a closer look at your favorite bird as it completes its annual migration using the Species Migration maps, discover which migratory birds use a given location and how they connect it to other places across the Western Hemisphere on the Locations maps, and learn about many of the challenges migratory birds face during the year with the Conservation Challenges maps.
