One reason these odd collective nouns haven't been assigned to Peregrines or Great Horned Owls is just that those birds don't noticeably flock. Come to think of it, the connotations of "flock" are mostly unflattering too. Etymologically, a flock is a crowd of followers, whose collective behavior doesn't display individual initiative. Think of sheep, or rustic parishioners.
