How does the size of a ferruginous hawk compare to a Red-tailed hawk?

The ferruginous hawk is indeed generally larger than the red-tailed hawk. In terms of size, the ferruginous hawk is characterized by a larger wingspan and overall body length, making it one of the largest species of hawks in North America. This size advantage can be critical in terms of hunting capabilities and adaptability to various environments.

The comparison of sizes is significant in falconry and bird watching, as understanding the physical attributes of these birds aids enthusiasts and practitioners in identifying and selecting the right species for their respective pursuits. The other options do not relate directly to size. While the defense of nests or classification as a Parabuteo may be interesting aspects of the hawks, they do not pertain to the size comparison between the two species.
