Which hawk is likely identified by a dark back and a brown breast, with a round-tipped tail?

The Cooper's hawk is indeed recognized by its distinctive physical characteristics, including a dark back and a brown breast. The round-tipped tail is another key identifying feature of this species. When observing Raptors, the coloration and tail shape are critical factors in distinguishing one from another. The dark back helps to provide a certain sleekness and camouflage in wooded environments, while the brown breast can aid in blending into those same habitats.

While other hawks on the list may share some similar characteristics, they differ in significant ways. For instance, the immature goshawk tends to have more mottled plumage and a more robust body than a Cooper's hawk, lacking the same specific coloration pattern. The red-shouldered hawk, while having a broad range of color, typically features more reddish hues in both its shoulders and breast, setting it apart from the brown breast of a Cooper's hawk. The sharp-shinned hawk, although also relatively small and similar in habitat, is typically recognized by a more squared-off tail and different feather patterns that do not exhibit the same dark back and brown breast combination. Hence, the distinct traits of the Cooper's hawk make it the correct identification in this scenario.
