It rained heavily the first time I had planned to go on a hawk watch, and the trip was cancelled. But the rain brought with it a weather front the next day that created the perfect conditions for fall hawk migration. And migrate they did.

Carried aloft by rising currents of warm air and light winds from the north, many of those birds may have traveled a hundred miles that day without ever flapping their wings.
Despite the diversity and impressive numbers of raptors, there was one species that stood out to all of the hawk watchers: the broad-winged hawk.
