@Sebastian Brosig Re: Short-sighted?
"I keep bees, and while they don't talk to me about their eyesight specifically, I must assume they possess pretty good at-a-distance vision as well as short-range, they find their own hive with amazing accuracy, and they do that by sight. If you were move the bee hive by a couple of feet then most of them wouldn't find it their way home any more."
