The data of the birds’ migrations in these maps create beautiful paths that flow from North America, down to Central America, the Caribbean, and down to South America.
You can specify a particular species, and track its movement, showing just how dynamic and well traveled our avian friends are.
“The Bird Migration Explorer is your guide to the heroic annual journeys made by over 450 bird species, and the challenges they face along the way.”
We love the way the migration paths become well traveled corridors, represented by colored lines. It gives a bit of context to the flocks of birds you see flying overhead. Via Kottke:
