What distinguishes Cooper's hawks from sharp-shinned hawks besides tail shape?

The distinction between Cooper's hawks and sharp-shinned hawks in terms of body size is significant because it is one of the most noticeable differences between the two species. Cooper's hawks are generally larger, with longer wings and a more robust build, while sharp-shinned hawks are smaller and more slender, which affects their hunting techniques and prey selection.

Understanding these physical differences can help in identifying the species in the field. For instance, while both hawks have similarities in their hunting habits and coloration, the size disparity is typically apparent when the two are observed together or in flight, making body size a more reliable distinguishing factor. It's important to note that while hunting speed, feeding habits, and color patterns can vary, they often overlap between the two species and do not serve as definitive identifiers like body size does.
