I often can spot more than one hawk at a time over my fields. But they usually are no more than two in close proximity to each other. Buzzards, on the other hand may be in the dozens over my place and have been known to light on my roof peak and rest a while! This white oak tree pictured full of buzzards is about 100 feet from my house. I have a picture of them lined up along my roof line, but it is not currently downloaded to my computer. A pair of American Kestrels(sparrow hawks) or Red Tailed Hawks hunting together is common in the spring time through early summer and later I may see them joined by a juvenile bird or two. I also see Falcons, Marsh Hawks, Rufous Tailed Hawks, Mississippi Kites and more. An occasional Bald Eagle may fly over ,coming and going from nearby wetland areas. Screech owls live in that oak tree pictured and nearby ones as well as other larger species of owls. A buzzard usually does not go after fast moving critters, but I have heard reports of them doing so and snatching a chicken from old timers. They clean up after the cars, coyotes, fox , big cats and hunters around here. They also work the stillborn/ afterbirth from herds of cattle and flocks of sheep.
