Which characteristic is true about the most common hawk found in North America?

The correct answer highlights a defining feature of the red-tailed hawk, which is indeed the most common hawk found in North America. One of the most recognizable traits of this bird is its distinct red tail, especially prominent in adult individuals. This characteristic not only aids in the identification of the species but also plays a role in its mating displays and behavioral interactions. The red tail is particularly striking against the backdrop of the hawk's more neutral body plumage, making it a celebrated symbol among bird watchers and nature enthusiasts.

The other characteristics presented in the options pertain to different types of birds or behaviors. For example, while some species may hunt at night, the red-tailed hawk is diurnal, meaning it is active during the day. Additionally, while the red-tailed hawk is certainly large in size, it is not the largest hawk species; that title goes to others, such as the ferruginous hawk. Although hawks can exhibit social behaviors in certain contexts, the red-tailed hawks are typically solitary hunters, often seen alone or with a mate rather than in groups.
