True or False: The sole member of the genus Parabuteo is the Harris' hawk.

The statement is false. The genus Parabuteo refers specifically to a category of hawks in the family Accipitridae, where the Harris' hawk, or Parabuteo unicinctus, is indeed the primary representative. However, it is not the sole member of this genus, as there may be other species classified within Parabuteo, depending on taxonomic revisions and updates in ornithological research. This genus includes the Harris' hawk but also historically encompassed a few others, making the assertion that it only consists of the Harris' hawk inaccurate. Understanding the classification helps in appreciating the diversity within hawks and the importance of ongoing research in taxonomy, which can sometimes lead to changes in how species are categorized.
