'Seahawks' Don't Exist, Except When Winning Football Games

It's a little known fact, especially since they won the Super Bowl, but in actuality there is no bird in ornithology known as the seahawk. Multiple sources, including the Seattle Seahawks' own website admits that seahawks don't exist.
Ospreys on the other hand do. Those are the birds found throughout the Puget Sound area of Oregon which are also known as fish eagles or fish hawks. Ospreys are the only member of the hawk family that are exclusively fishers.
