Telling a Cooper’s hawk vs sharp-shinned hawk apart is birding’s ultimate puzzle.

You’ll notice Cooper’s hawks are crow-sized with square heads and dark caps, while sharp-shinned hawks are jay-sized with rounder heads.

Cooper’s have rounded tail tips that look like they’ve been dipped in white paint, whereas sharp-shinned tails appear square-cut.

In flight, Cooper’s project their larger heads forward like they’re surveying their kingdom, while sharp-shinned hawks keep a more compact profile.

Size overlap between small male Cooper’s and large female sharp-shinned makes things tricky, but these subtle clues will help you crack the code to identify Cooper’s hawks and understand the size overlap.

Cooper’s Hawk Identification

When you spot a Cooper’s Hawk, look for its hefty, crow-like body and a big blocky head that could rival a football helmet.

If you catch yourself squinting at a backyard visitor with a stern stare and a tail that curves like a “C”, you’ve probably found your bird—just don’t expect it to pose for a selfie.

Size and Weight

You’ll almost always spot the Cooper’s Hawk by its robust body and crow-like size.

Don’t get tricked by size deception—sexually dimorphic hawks mean females tower over males! Sometimes, weight overlap adds to the confusion.

Use measurement metrics for any hawk size comparison. Knowing the average hawk dimensions can greatly aid identification.

In short, sharp shinned hawks look dainty, while Cooper’s bring bouncer energy to your backyard.

Head Shape and Nape Color

If size throws you off, shift focus to head shape and nape color. A Cooper’s Hawk’s head is blocky and big, topped with pale nape feathers for that “capped” look.

Check the stern facial expression and eye placement close to the beak—kind of like a grumpy librarian. Many enthusiasts even purchase Coopers hawk merchandise to show their appreciation.

• Spot those “capped” nape feathers
• Blocky head = Cooper’s Hawk
• Eye placement helps with hawk identification

Tail Shape and Flight Characteristics

While head shape can help, pay close attention to tail shape and flight characteristics for hawk identification.

Cooper’s Hawk shows a rounded tail with bold Tail Bands and a white tip, plus head projection during flight.

Its Wingbeats are deep and steady, followed by a smooth gliding style.

One key difference between the two species is their size and build.

If you blink, you might miss its impressive flight speed!

Juvenile Vs Adult Plumage

Juvenile plumage on a Cooper’s Hawk throws you for a loop—think brown stripes on the chest (not those grown-up bars).

As for adult markings, you’ll spot that blue-gray back and orange chest. Eye color? Youngsters have yellow, adults turn orange-red.

Nape contrast stands out in grown birds. Their stealthy hunting strategies are key to their survival.

• Brown stripes (juvenile)
• Blue-gray backs (adult)
• Orange chest (adult)
• Shifting eye color

Sharp Shinned Hawk Identification

When you spot a Sharp-shinned Hawk, pay close attention to its petite frame and bug-eyed look—think of a Blue Jay with a secret superhero disguise.

It’s tricky not to confuse it with a Cooper’s Hawk, but once you notice that small, rounded head and snappy, flapping flight, you’ll be one step ahead in the hawk-spotting game.
