There is a reason that so many nations, from Rome, Russia, Austria-Hungary to the United States choose the Eagle as their national bird. It is a powerful creature. Decisive. Fearless in the face of uncertainty and utterly confident in its own abilities to achieve its end. Other birds, such at the turkey though fierce when cornered, run, hide, and depend upon camouflage for survival.
But all that, though true, pales in comparison to having a bad ass looking symbol and the Eagle is just simply bad ass!
