The initial logo for the team was a black falcon with a red outline, and the falcon’s head and talon protruded from its body to form the capital letter, “F.” This logo was kept for over 23 years but in 1990, the falcon’s red outline was changed to black. This logo lasted for 12 years until 2003, when the logo was changed to its current state. The change was likely initiated as a result of modernization because the Falcon got a sleeker redesign so that it appears to be inflight and received silver and red accents to make it look more powerful and aggressive while still resembling a capital letter “F.”
The Falcons logo was designed by Verlander Design.
