I agree, so I looked for information in BNA.

My brother John co-wrote the BNA piece about Cooper's Hawk. Here is a
snippet about soaring behavior.
"Soars frequently in breeding (Fischer 1986) and other seasons. In both
sexes, also a high, slow, rocking flight with exaggerated wingbeats, much like
nighthawk (Chordeiles), often with under tail coverts laterally flared and (at
least in male) ?kik? calls (ref. in Meng and Rosenfield 1988). Such flight
has been ascribed to courtship display but also occurs in migrants (Berger
1957) and fledglings (Layne 1986)."

cooperii), The Birds of North America Online (A. Poole, Ed.). Ithaca: Cornell Lab of
Ornithology; Retrieved from the Birds of North America Online:

But then, so do Goshawks.
"Soars occasionally during migration and during courtship over nest stands"
as in the Gos account from the same source.
