The eagle used as the emblem for the US 101rst Airborn Division is actually Old Abe, a real bald eagle.
Old Abe was the mascot of a Wisconsin civil war regiment, the 8th volunteer infantry.
Old Abe was captured by Chief Sky of the Ojibwe tribe as an eaglet and traded to a man from the Eau Claire area for a bushel of corn. From here Old Abe found his way to the regiment.
The 8th was deployed as far south as Vicksburg. The Wisconsin monument at the Vicksburg memorial battle grounds has a stature of Old Abe.
Confederates referred to Old Abe as "Yankee Buzzard"
Old Abe became a national celebrity during the war and was quite famous after. He was invited to the centennial celebration in Pennsylvania amongst other national events. He was given a 2 room apartment and a full time caretaker within Wi state capitol.
Some years later, a fire broke out at the capitol. Old Abe alerted people in the building, but smoke inhalation caused him to pass a few days later.
His remains were preserved in a mount, and kept in the capitol. It is said Teddy Roosevelt had fond words when he was able to view the mount about the mascot he had heard about as a child.
In 1904, the WI capitol building burned, and Old Abe's mount among many historic artifacts were lost.
Today, a replica of Old Abe is displayed in the capitol building.
Old Abe was also incorporated into the J.I. Case company logo that built farm equipment in Racine, WI. J.I. Case started in 1842(before WI was an official state) and lasted in that initial form until the early 1970's when it merged with David Brown. Case dropped the Old Abe logo in 1969. The image of Old Abe on top of the globe (no words) can be found in all sorts of parts/castings for Case tractors.
This all came to mind as I was at Symco at the thresheree today watching some pre-WW2 era Case tractors in the tractor pull.
