As millions of birds are flocking to their wintering grounds, the Smithsonian Migratory Bird Center and nine partner organizations announced today the Bird Migration Explorer, a state-of-the-art digital platform that reveals migration data consolidated for 458 bird species found in the United States and Canada. The free, interactive platform, available in English and Spanish, allows users to see the most complete data collected on migratory species in their neighborhoods and where those birds go throughout the year. The Bird Migration Explorer reveals insights about the journeys of individual species, the connectedness, through migratory birds, of any given location in the hemisphere, and also details how migratory birds encounter 19 different conservation challenges. For example, at least 299 species connect New York City to at least 30 other countries and territories in the hemisphere, including places as far away as Argentina and Uruguay. And, the famous “River of Raptors" migration corridor in Veracruz, Mexico, is a hub connecting the extreme northern and southern ends of the globe.
