California’s mix of deserts, wetlands, oak woodlands, and coastal mountains pulls in more hawk diversity than almost any other state in the country. Some species stick around all year and nest on freeway light poles; others pass through for a few weeks each year and vanish just as quickly.
This guide covers all 14 types of hawks in California that birders and backyard watchers can realistically expect to encounter, from the ubiquitous red-tailed hawk to rarities that barely cross the border from Arizona. Each section breaks down what the bird looks like, where it tends to show up, and what sets it apart from its lookalikes.

| Red-tailed Hawk | 19–25 in | Statewide | Year-round |
| Red-shouldered Hawk | 17–24 in | Coastal and Central CA woodlands | Year-round |
| Cooper’s Hawk | 14–20 in | Statewide, suburbs and woodlands | Year-round |
| Sharp-shinned Hawk | 9–13 in | Forests statewide | Fall and winter |
| Northern Goshawk | 18–27 in | Northern CA and Sierra Nevada conifer forests | Year-round (uncommon) |
| Swainson’s Hawk | 19–22 in | Central Valley grasslands | Spring and summer |
| Ferruginous Hawk | 22–27 in | Central Valley and open desert | Winter |
| Rough-legged Hawk | 18–23 in | Open fields statewide | Winter |

| Broad-winged Hawk | 13–17 in | Mostly coastal | Rare fall migrant |
1. Red-tailed Hawk
The red-tailed hawk (Buteo jamaicensis) is the bird most people picture when they hear the word “hawk,” and for good reason. This species occupies a broad range of habitats from central Alaska south to Venezuela and east to the Virgin Islands, making it one of the most widespread birds of prey in North America. In California specifically, researchers describe the species as common to abundant throughout the state.
Adults show a rich brown back and pale, streaked underparts, with the signature brick-red tail visible from below as a soaring silhouette. Juveniles lack the red tail entirely, showing brown barring instead, which trips up a lot of new birders. Wild individuals have been recorded living as long as 29.5 years, far beyond what most people assume for a wild raptor.
Look for them perched on freeway light poles, fence posts, and dead snags in open country, or soaring in wide, lazy circles over grasslands and agricultural fields. They hunt mostly ground squirrels, gophers, and other small mammals, which makes farmland and the edges of rattlesnake habitat prime real estate for them.
Pro Tip: If a large hawk is perched and you can’t see the tail color, check the belly instead — most red-tails show a band of dark streaking across the belly that contrasts with a pale chest.
2. Red-shouldered Hawk
The red-shouldered hawk (Buteo lineatus) is a vocal, mid-sized buteo that favors wooded areas near water. Adults have brownish heads, reddish chests, and pale bellies with reddish bars, along with long tails marked by narrow white bars, and the red “shoulders” that give the species its name are visible when the bird is perched.
A distinct subspecies lives along the West Coast, primarily in California, and this coastal population remains stable and year-round even though the species is less common overall than the red-tailed hawk. They favor riparian woodlands, oak groves, and increasingly, leafy suburban neighborhoods with mature trees and a nearby creek.
Key Insight: A study of red-shouldered hawk home range in Southern California found an average territory of about 1.2 square kilometers, with the species showing fair adaptability to human-altered landscapes even as riparian forest habitat in the Central Valley declined by roughly 98 percent between 1850 and 1977.
Their diet leans heavily on amphibians and reptiles in addition to small mammals, which is why they’re often spotted hunting along stream banks where frog populations and salamanders concentrate. Listen for their sharp, repeated “kee-ah” call — it often gives away their location before you spot the bird itself.
3. Cooper’s Hawk
The Cooper’s hawk (Accipiter cooperii) is the backyard bird-feeder predator that sends songbirds scattering. It measures between 14 and 20 inches long, roughly the size of a crow, with short rounded wings and a long tail built for weaving through trees at speed.
Adults have bluish-gray backs, blackish caps, and white undersides barred with reddish-orange, and females run nearly a third larger than males. Juveniles look markedly different, showing streaked brown chests instead of the adult’s rufous barring, which can make age identification tricky at a glance.
Cooper’s hawks thrive in suburban neighborhoods, city parks, and mixed woodlands across the state, and they’re quick to exploit the steady supply of mourning doves and other songbirds drawn to backyard dove populations and feeders. Their flight style — several quick wingbeats followed by a short glide — is one of the easiest field marks to learn.
Pro Tip: Cooper’s hawks have a rounded tail tip, while the very similar sharp-shinned hawk has a squared-off tail. Checking the tail shape is faster than trying to judge overall size in the field.
4. Sharp-shinned Hawk
The sharp-shinned hawk (Accipiter striatus) is the smallest hawk found in California and the Cooper’s hawk’s look-alike cousin. Males can be barely larger than a jay, while females run noticeably bigger, a pattern typical across accipiters.
Adults share the same slate-gray back and rufous-barred underside as a Cooper’s hawk, so most birders lean on proportions rather than color: a smaller, rounder head, a thinner neck, and a squared tail tip separate this species from its larger relative. Flight style also helps, since sharp-shinned hawks flap more rapidly and erratically between glides.
They nest in dense conifer forests in the northern part of the state and the Sierra Nevada, then disperse more widely across California in fall and winter, showing up in wooded suburbs and along hedgerows wherever small songbirds concentrate. Compare their range to the raptor lineup found in the upper Midwest in this guide to hawks in Wisconsin, where several of the same accipiters and buteos overlap seasonally.
5. Northern Goshawk
The Northern Goshawk is the largest and most powerful accipiter in North America, and one of the hardest California hawks to actually see. Many taxonomists now treat the North American population as the American Goshawk (Accipiter atricapillus), split from the Eurasian form in a 2023 revision, though plenty of field guides and older references still use the original combined name.
Adults show a blue-gray back, a pale gray-barred chest, and a bold white eyebrow stripe over a piercing red eye — a fierce look that matches their hunting style. They specialize in ambushing grouse, squirrels, and other mid-sized prey deep in mature forest, using short bursts of speed through dense cover.
In California, goshawks stick to high-elevation conifer forests in the north state and the Sierra Nevada, where they’re secretive, territorial, and rarely seen outside the breeding season. Birders chasing this species often have better luck in Colorado’s forested high country, covered in this guide to hawks in Colorado, where goshawk habitat is more extensive.
6. Swainson’s Hawk
The Swainson’s hawk (Buteo swainsoni) is a slim, long-winged buteo built for covering enormous distances. It breeds in the open grasslands and agricultural fields of California’s Central Valley through the warmer months, then undertakes one of the longest migrations of any North American raptor, wintering on the pampas of Argentina.
Plumage varies widely between light and dark morphs, but most birds show a contrasting dark chest band — sometimes called a “bib” — against a paler belly, along with narrow, pointed wingtips visible in flight. Unlike red-tailed hawks, Swainson’s hawks often forage on the ground in loose flocks, especially when following tractors or grass fires that flush out insects and small rodents.
Because they’re so tied to agricultural land, Central Valley farm country is the most reliable place to find them during the breeding season. For a comparison of how this species behaves in another major agricultural flyway, see this rundown of hawks in Kansas, where Swainson’s hawks are also common breeders.
7. Ferruginous Hawk
The ferruginous hawk (Buteo regalis) is the largest buteo in North America and a true open-country specialist. The name comes from the rust, or “ferruginous,” coloring on the legs and back, which contrasts with an overall pale, almost bleached appearance in flight.
These hawks nest on the Great Plains and in the Great Basin, then move into California’s Central Valley and desert grasslands as winter visitors, where they hunt ground squirrels, jackrabbits, and prairie dogs over wide-open terrain. Their broad wings and pale underside can make them look almost ghostly when soaring against a gray winter sky.
They favor the same flat, treeless expanses that attract other wintering buteos, often sharing grassland habitat with the hawks found across Oklahoma’s plains, another stronghold for this species outside the breeding season.
8. Rough-legged Hawk
The rough-legged hawk (Buteo lagopus) breeds far north in Arctic tundra and only reaches California as a winter visitor, typically arriving in the coldest months and departing by early spring. The name refers to feathers that extend all the way down the legs to the toes, an adaptation for life in frigid climates.
This species comes in light and dark morphs, but most California birds show a dark belly band, dark wrist patches visible from below, and a banded tail. One of its most distinctive habits is hovering in place over open fields while scanning for voles and other small rodents, a behavior less common in other California buteos.
Look for them over the same open grasslands and agricultural fields that attract wintering ferruginous hawks and northern harriers, particularly in the northern half of the state and the Central Valley.
9. Northern Harrier
The northern harrier (Circus hudsonius) is easy to pick out even at a distance thanks to its low, tilting flight over open ground and a distinctive white rump patch visible as it banks. Along with the red-tailed hawk, Cooper’s hawk, Swainson’s hawk, rough-legged hawk, ferruginous hawk, and northern goshawk, it’s one of the species most commonly listed among California’s resident hawks.
Males are pale gray above with black wingtips, earning them the nickname “gray ghost,” while females and juveniles are streaky brown. Both sexes have an owl-like facial disc that helps them locate prey by sound as well as sight, a trait shared with few other hawks.
Harriers hunt marshes, wet meadows, and grasslands statewide, flying low and slow just above the vegetation before dropping suddenly onto voles, mice, and the occasional ground-dwelling quail. Coastal wetlands and Central Valley wildlife refuges are especially reliable spots to watch them work a field.
10. Harris’s Hawk
The Harris’s hawk (Parabuteo unicinctus) is a desert specialist found only in the far southeastern corner of California, mainly around the Colorado River valley and Imperial County. Dark chocolate-brown overall, it shows chestnut shoulder patches, chestnut leggings, and a white band at the base and tip of an otherwise black tail.
What makes this species stand out isn’t just its range but its social behavior: Harris’s hawks are among the only raptors in the world known to hunt cooperatively in family groups, sometimes flushing out rabbits or ground squirrels in coordinated pack-style attacks. This teamwork has also made the species a favorite in falconry circles.
Important Note: Harris’s hawks have a limited, localized range in California. Outside the desert Southwest corner of the state, most “Harris’s hawk” sightings reported by casual observers turn out to be dark-morph red-tailed hawks or escaped falconry birds.
11. Zone-tailed Hawk
The zone-tailed hawk (Buteo albonotatus) is one of California’s rarest breeding hawks, found in small numbers along the lower Colorado River. Nearly black overall with a banded gray-and-black tail, it’s famous for a hunting trick: in flight, it closely resembles a turkey vulture, right down to the shallow V-shaped wing posture and teetering flight style.
This mimicry isn’t just coincidental. Biologists believe prey animals that have learned to ignore harmless, carrion-eating vultures overhead let their guard down when a zone-tailed hawk drifts into the same soaring flock, giving the hawk a split-second advantage when it finally stoops.
Finding one requires patience and a known riparian corridor, since the species breeds in very low numbers and only in a narrow strip of habitat along the river. Scanning vulture kettles carefully is often the only way to pick one out.
12. Gray Hawk
The gray hawk (Buteo plagiatus) barely qualifies as a California bird at all, with records limited to a handful of sightings along the Colorado River and adjacent desert riparian zones. Its core range sits in Arizona, New Mexico, and Mexico, making any California appearance notable among local birders.
Pale gray above with finely barred gray underparts and a tail marked by broad black-and-white bands, the gray hawk is a compact, agile buteo built more like an accipiter than a typical soaring hawk. It hunts lizards and small birds from a perch inside streamside cottonwood and mesquite groves rather than soaring over open country.
Because the species depends so heavily on intact riparian woodland, any loss of cottonwood habitat along the lower Colorado River directly threatens the handful of California records that do occur.
13. Common Black Hawk
The common black hawk (Buteogallus anthracinus) is a large, chunky, all-black hawk with a single broad white band across an otherwise dark tail. Like the gray hawk and zone-tailed hawk, its presence in California is restricted to riparian corridors along the Colorado River, where sightings remain rare and scattered.
This species feeds heavily on fish, frogs, and crabs and other crustaceans pulled from shallow streams, which ties it tightly to permanent water and streamside cottonwood-willow forest. It typically hunts by wading in shallow water or watching from a low perch rather than soaring at height like a typical buteo.
Because suitable riparian habitat along the lower Colorado has shrunk over the decades, sightings in California are now considered casual rather than predictable, and most records come from experienced birders specifically targeting the species’ known haunts.
14. Broad-winged Hawk
The broad-winged hawk (Buteo platypterus) is a small, compact buteo best known for the massive migratory flocks, or “kettles,” it forms over the eastern and central United States each fall. In California, it’s strictly a rare but regular vagrant, turning up most often along the coast during fall migration watches.
Adults show a reddish-brown barred chest and a tail with bold black-and-white bands, visible even at a distance when the bird is soaring. During migration, broad-winged hawks supplement their usual diet of small mammals and amphibians with large insects, making them opportunistic feeders on the move.
Raptor migration counts at coastal watch sites occasionally log a handful of broad-winged hawks each autumn, usually mixed in among far larger numbers of red-tailed and Cooper’s hawks heading south. Spotting one typically requires picking through a kettle of more common buteos rather than finding an isolated bird.
Conclusion
California’s hawk lineup ranges from birds you can expect to see on any drive through farm country to species that require a dedicated trip to a specific stretch of the Colorado River. Learning a handful of field marks — tail shape, wing silhouette, flight style, and habitat — goes a long way toward sorting out which of these 14 species you’re looking at.
For birders building out a broader raptor life list, comparing California’s species against neighboring states can help clarify which field marks are truly diagnostic versus which vary by region. If you’re curious how California’s hawk diversity stacks up elsewhere, both the Kansas and Oklahoma raptor communities share several overlapping species shaped by similar open-country and agricultural habitat.
