4. 16 April 2012, Huge Raptor Migration on NEXRAD (4 Parts)

This loop shows two hours ending at 5pm DST. There are very few hawks here (so you can compare to earlier loops with birds), but the frontal boundary is approaching. There is precipitation and low pressure compromising favorable flight conditions into the area from the west.
