Which term refers to members of the genus Buteo?

The term referring to members of the genus Buteo is "Broadwings." Buteos are a group of birds of prey that are commonly known for their broad wings and robust bodies. This genus includes various species such as the Red-tailed Hawk and the Rough-legged Hawk, which are characterized by their wide wings that allow for soaring flight patterns. Broad wings are essential for these birds, as they enable them to glide efficiently on thermal updrafts while searching for prey.

The other terms do not correctly describe the genus Buteo. For instance, "Long wing" and "Short wing" do not specifically correlate with Buteo characteristics, as there is no genus that encompasses such defined traits based solely on wing length. "Tiercel" is a term used specifically to refer to male falcons, particularly among those in the genus Falco, and is unrelated to the Buteo classification. Thus, "Broadwings" is the correct descriptor for members of this genus, highlighting their notable physical features.
