Which of the following raptors can change the orientation of their talons to grip effectively?

The correct choice highlights the unique adaptability of both the osprey and the great-horned owl in using their talons effectively. In particular, the osprey has special adaptations that allow it to rotate its outer toes to provide a stronger grip on slippery fish, which are its primary prey. This rotating capability enhances their hunting efficiency in aquatic environments.

The great-horned owl, on the other hand, possesses a similar ability to adjust its grip due to its flexible toe orientation. This characteristic allows it to capture and hold onto a variety of prey, including mammals and birds, with greater strength. Their powerful grip is critical for their survival, as it helps them secure their food effectively.

In contrast, the other options include raptors that do not exhibit the same flexibility in their talon orientation. While all raptors have strong talons suited for gripping prey, not all have the specialized ability to change the orientation of their talons to enhance their grip.
