They were indeed the RedTAILS, not hawks.
From their history page:
“The Allies called these airmen “Redtails” or “Redtail Angels,” because of the distinctive crimson paint applied on the vertical stabilizers of the unit’s aircraft.[7]”

The article I posted was only an excerpt. Here is a section of the article that I didn't excerpt that explains the name "Red Hawk."
The name Red Hawk honors the legacy of Tuskegee Airmen and pays homage to their signature red-tailed aircraft from World War II... The name is also a tribute to the Curtiss P-40 Warhawk, an American fighter aircraft that first flew in 1938 and was flown by the 99th Fighter Squadron, the U.S. Army Air Forces first African American fighter squadron.So "Red" for the Tuskegee Red Tails, and "Hawk" for the P-40 Warhawk.
