As hawk watch locations across North America start hiring and counting migrating raptors, the raptors themselves are gearing up to head wherever. I’ve had the opportunity to see and photograph a lot of raptors in the past two years. The two common accipiter hawks, the sharp-shinned hawk (or “sharpie”) and Cooper’s hawk are often mistaken for one another. While the sharpie is usually considerably smaller than the Cooper’s, size can be difficult to judge in the field. Sharp-shinned hawks often travel in pairs during migration.

I hope this graphic helps you to visualize some of the differences between these two species.
