That's true. How high you are does not matter when the wind is blowing at an awkward angle. Also, think about how easy it would be from 70 yards to see a bow, shaking and moving downward, while hovering in the air? I'd say they saw you, and will be cautious for a day or two. But then, if pre-rut and gun season (muzzleloader here) hasn't spooked them, they'll be acting normal in no time.
