Camouflage

Nature provides the utmost greatest circumstance for things to be hidden by camouflage.  Between sunlight and shadows, shades and patterns of color, even movement of blowing leaves, things right before your eyes might be difficult to see.  Here are a few I've come across.

Can you see the child hiding in the next picture?

Ha!  Funny, how a child will think just because they cover their own eyes, it makes them invisible; they cannot see, therefore they cannot be seen--like they are camouflaged by their own hands.  That's why the "Peek-A-Boo!" game is so much fun!
