What distinguishes most Cooper's hawks from most sharp-shinned hawks?

The distinguishing feature of Cooper's hawks compared to sharp-shinned hawks is typically the more rounded tip of the tail found on Cooper's hawks. This characteristic is significant as it aids in identification when observing these birds in the wild. The rounded tail shape provides a clue about the bird's flight style and hunting techniques, contributing to its overall behavior and adaptation in its environment.

In contrast, sharp-shinned hawks possess a more squared-off or slightly notched tail, which is another key identification marker. While size and wingspan may vary between species, the notable difference in tail shape serves as a primary visual cue distinguishing these two types of hawks. The coloration of their plumage may show variations, but these do not serve as the most reliable visual indicator for distinguishing the two.
