Leucism is a genetic condition characterized by partial loss of pigmentation, which results in lighter coloration in animals. In the case of Red-tailed Hawks, the presence of leucistic individuals is indicated by their white feathers. Unlike typical Red-tailed Hawks that exhibit a variety of dark and reddish plumage, leucistic individuals display abnormal coloring, which primarily manifests as a white or very pale appearance.

This distinct coloration stands out and is a key marker of leucism, distinguishing these individuals from others within the species. The presence of white feathers is a clear indicator of this genetic trait, making it the correct choice in identifying leucistic Red-tailed Hawks. Other options, such as dark coloration, standard coloration, or lack of markings, do not accurately describe the unique attributes of leucistic individuals.
