Stupid Signs

Look closely at these pictures. Notice the sign at the bottom of the long pole to the high rise birdhouse. Read the close up of the sign in the second picture. Who is this sign for? Is it a warning to a literate cat that likes to shimmy up poles in hopes of catching a bird? Or is it for birds that can't fly, but can read? Do their friends drop down a rope ladder or something? Why is this area booby trapped? I was baffled by this. But, booby trapping places with sand spurs will work. If you have ever stepped on a patch of them you understand.
