DESCRIPTION

This short movie is a cool "visualization" of how Purple Martins move northward across the landscape in late winter and early spring, how numbers peak at sites and then decline in late summer and early fall. The visualization is created with eBird observation records entered by thousands of eBird users across the hemisphere.
