Which of the following types of raptors can be maintained on a diet consisting solely of fresh-killed rodents?

The correct understanding of this question lies in recognizing that all the raptors listed can indeed thrive on a diet of fresh-killed rodents. Red-tailed hawks, goshawks, and kestrels are all capable of consuming a variety of small mammals, with rodents being a significant part of their natural diets in the wild.

Red-tailed hawks are versatile hunters and are often observed preying on rodents, which constitute a considerable portion of their food intake. They can adapt their hunting strategies and are highly effective in capturing these small mammals.

Goshawks, known for their agility and speed, also have a diet that includes rodents. Their hunting prowess allows them to target various prey, but rodents are frequently found in their diet due to their availability and abundance.

Kestrels, while smaller than the other two species, primarily hunt small mammals and insects. Fresh-killed rodents are suitable for them and are part of their natural foraging behavior.

Since each of these raptor species can maintain a healthy diet with fresh-killed rodents, the inclusion of this option indicates a broader understanding of raptor dietary needs and their adaptability to a diet focused on rodent consumption. Thus, the answer encompasses all the species, confirming that they can all thrive on a diet
