Which of the following is an official state symbol of Illinois?

The White-tailed Deer is indeed recognized as an official state symbol of Illinois. This designation reflects the state's natural heritage and recognizes the significance of the White-tailed Deer to Illinois' ecosystems as well as its popularity among residents for recreational activities such as hunting and wildlife observation.

In state symbolism, the White-tailed Deer embodies qualities like grace and strength that resonate with Illinoisans. This designation aligns with the state's appreciation for wildlife and conservation, making the White-tailed Deer a representative figure of Illinois’ natural environment.

While the Gray Fox, Cardinal, and American Goldfinch have their own representations and importance in Illinois' cultural and ecological landscape, they do not hold the same official status as the White-tailed Deer. The Cardinal is notable as the state bird, and the American Goldfinch is recognized for its vibrant color, yet the legislative recognition of the White-tailed Deer solidifies its role as an official state symbol.
