What is a notable behavioral trait of Buteos during flight?

Buteos, a genus of large birds of prey, are well-known for their distinctive soaring flight style. One notable behavioral trait is their ability to soar with minimal wing flaps. This is primarily due to their broad wings and large body size, which allow them to take advantage of thermal updrafts in the atmosphere. By utilizing these thermals, Buteos can maintain altitude with little energy expenditure, making it efficient for them when searching for food.

This soaring behavior is particularly advantageous for hunting, as it provides them with a wide vantage point to spot potential prey on the ground without the need for constant flapping, which could tire them out. The other choices, while they may describe behaviors of different raptor species or contexts, do not accurately reflect the primary flight characteristic of Buteos. For instance, high-speed chases and short, rapid bursts of speed are more characteristic of falcons, while complex aerial displays are often associated with mating rituals in some birds but are not a defining trait of Buteos during regular flight.
