Hawks Size in Arizona

What is the size range of hawks in Arizona?

Arizona hosts several hawk species with wingspans from about 20 inches (Sharp-shinned) to over 50 inches (Ferruginous). The most common, the Red-tailed Hawk, measures 18-26 inches long with a wingspan of 45-52 inches. Use a general rule: if it's smaller than a crow, it's likely a Sharp-shinned or Cooper's; if larger than a crow, consider Red-tailed, Swainson's, or Ferruginous.

In Arizona, hawks sightings usually improve when you slow down and match your first stop to the most useful ID markers and likely lookalikes. Use thestate wildlife huband theroute guideto narrow your first area, then check access, weather, and distance before you...

How can you use size to identify hawks in Arizona?

For a beginner, the most useful size signals are body length and wingspan relative to familiar birds. Compare to a crow (17 inches) or a goose. Also note the shape: buteos (chunky, broad wings) vs accipiters (long-tailed, short wings). Practice by observing perched hawks and checking field guides. Ourhawk identification guideprovides detailed size comparisons.

Where does size matter most when spotting hawks in Arizona?

Size matters most in open habitats like the Sonoran Desert or grasslands, where you can see the full silhouette. In wooded areas, size is harder to gauge. During migration (spring and fall), you'll see hawks at varying distances – use size to separate species. Start scanning from the largest (eagles) down to the smallest (kestrels).

What is the size difference between male and female hawks?

Female hawks are typically 20-30% larger than males, a trait called reverse sexual dimorphism. This is most noticeable in accipiters like Cooper's Hawk: females can be crow-sized, males are more like a jay. When comparing two hawks together, the larger one is almost always female.

How does hawk size compare to other birds of prey in Arizona?

Hawks are medium-sized raptors. Bald eagles are much larger (28-38 inches), while American Kestrels are much smaller (9-12 inches). Owls overlap in size but have broader bodies and larger heads. A practical field note: if you see a large raptor with a white head, it's a bald eagle; if it has a reddish tail, it's likely a Red-tailed Hawk.

When is the best time of year to see hawks of different sizes in Arizona?

Spring and fall migrations bring the highest diversity, with large Swainson's and Ferruginous Hawks passing through. Winter concentrates Red-tailed and Rough-legged Hawks in lowlands. Summer is good for resident Cooper's and Harris's Hawks. Timing affects which size classes you'll encounter – plan your trip around the season.
