What type of bird is not included when using the term "hawk"?

The term "hawk" specifically refers to birds of prey that belong to the family Accipitridae and other related groups. Generally, when people mention "hawks," they are thinking of species commonly recognized under that name, such as members of the genus Accipiter and Buteo.

While falcons are also birds of prey, they belong to a different family known as Falconidae. This distinction is critical because it defines the specific biological classification of these birds. Hawks have certain characteristics and behavioral traits that differentiate them from falcons, such as flight patterns, hunting methods, and physical build.

Eagles, which fall under the same family as hawks (Accipitridae), share a lot of similar features with hawks and are thus included when referring to hawkish birds. Vultures also belong to the Accipitridae family, particularly within the subfamilies that involve vultures, making them part of this classification.

Therefore, since falcons represent a separate family that does not fall under the general category associated with hawks, they are correctly identified as not being included when one casually uses the term "hawk."
