I'm not 100% sure of ID. Suggestions by iNat were also Red-Tailed and Cooper's. There is a Cooper's nest nearby, but it was in the nest when we passed it, and this was immediately afterward. I didn't see any red in his tail, so I chose Broad-Winged. If anyone has better knowledge, please let me know...I have a hard time IDing hawks

3 hawks in backyard. One eating a squirrel, one observing perched on swing, and one perched on a play structure and vocalizing constinously, until it got a turn at the squirrel. They were there more than 20 minutes!

Last photo shows how far away this raptor was, sitting on the fence post overlooking the grassland. Red-tailed Hawk or Red-shouldered Hawk?

Comparison of 3 Hawks commonly seen in Monterey County: Red-tailed Hawk (Buteo jamaicensis), Red-shouldered Hawk (Buteo lineatus), and Cooper's Hawk (Accipiter cooperii):

Western Red-tailed Hawk (Buteo jamaicensis ssp. calurus) Range map of subspecies: National Geographic Field Guide to the Birds of North America, ed. Jon L. Dunn, 7th ed., 2017, p. 567.

Red-tailed Hawk (Buteo jamaicensis) is a large, widespread, migratory bird of prey in the Accipitridae family. It is probably the most common hawk in North America. Length is 56cm (22 inches); wingspan 127cm (50 inches) with rounded wing tips. The darker head gives it a "hooded" appearance. Pale breast contrasts with darkish head, mottled belly and "V" shaped belly band (more visible in adults). Juveniles have gray-brown tails with many blackish bands. They have a white chest with heavily mottled belly (streaked and spotted with brown coloring on lower abdomen). It is bulky and broad-winged, designed for effortless soaring. It is seen in open country, commonly perched on roadside poles or sailing over fields and woods. Although adults can usually be recognized by the trademark reddish-brown tail, the rest of their plumage can be quite variable. Western birds are typically darker. Immatures do not have a red tail. There are many subspecies.
The Red-tailed Hawk occupies a wide range of habitats and altitudes, including deserts, grasslands, coniferous and deciduous forests, agricultural fields, and urban areas. It favors varied habitats with open woodland, woodland edge and open terrain. All buteos may be noted for their broad wings and sturdy builds. They frequently soar on thermals at midday over openings in the terrain. Red-tailed Hawk is legally protected in Canada, Mexico, and the United States by the Migratory Bird Treaty Act.

COMPARED TO another Buteo:

Red-shouldered Hawk (Buteo lineatus) is a medium-sized raptor, 38-48 cm (15-19 inches) long. Buteos are high-soaring hawks. Adult has reddish-orange shoulders. Wings have bold black-and-white checkerboard patterning. Tail is black with white bands. Tail is shorter than Cooper's Hawk (Accipiter cooperii).
"Diet includes small mammals, amphibians, reptiles, birds. Diet varies with region and season. Main items often mammals such as voles and chipmunks, at other times frogs and toads; may eat many crayfish in some areas. Also eats snakes, small birds, mice, large insects, occasionally fish, rarely carrion. Usually hunts by watching from a perch, then swooping down when it locates prey. Sometimes it flies very low in open areas, taking creatures by surprise."
There are several subspecies. In the Western U.S., we have the California Red-shouldered Hawk (Buteo lineatus ssp. elegans).

COMPARED TO

Cooper's Hawk (Accipiter cooperii) is a medium-sized hawk in the Hawks, Eagles, and Kites (Accipitridae) family. Cooper's Hawk has a long tail with black horizontal stripes and short rounded wings, giving this woodland hawk great agility. "Flight is several quick wingbeats and a glide. Females are larger than males. Looks similar to Sharp-shinned Hawk, but is larger with a bigger head. Cooper's Hawk has a long rounded tail tip, unlike Sharp-shinned Hawk that has a squared off tail tip.
Diet is mostly medium size birds and small mammals. Usually hunts by stealth, moving from perch to perch in dense cover, listening and watching, then putting on a burst of speed to overtake prey. Sometimes cruises low over ground, approaching from behind shrubbery to take prey by surprise."
Conservation Status: Apparently secure (S4) in California, US (NatureServe). Was S3; See: https://explorer.natureserve.org/Taxon/ELEMENT_GLOBAL.2.100417/Accipiter_cooperii
