Which is the largest eagle species in North America?

With a wingspan topping seven feet, Golden Eagles are the largest hunting birds in North America. And they aren't just big birds — Golden Eagles are among the most formidable winged hunters in the world, capable of diving on prey at speeds approaching 200 miles per hour. While subsisting typically on rabbits, squirrels, and prairie dogs, Golden Eagles have been known to feed on much larger animals, including seals, bighorn sheep, pronghorn, coyotes, and bobcats.
