- Nicknamed the "grasshopper hawk," Swainson's Hawk undertakes one of the longest migrations of any North American raptor — roughly 7,100 miles (11,400 km) round-trip to the Argentine pampas, lasting at least two months — with nearly the entire population funneling through the narrow Isthmus of Panama in migratory "kettles" of thousands of birds.
