Answer 1

When hunting turkeys, I seldom see a turkey outright in the twilight, but what I do see are boundries of turkey shapes when they move. I notice when watching my bees fly against the background sky, I don't see the bee at all, but see the edges of them moving against the blue background. Of course, each time I have to decide is it a bird, plane, or superman. But is the edges I see.
