Squirrels are known to steal food from bird feeders - here is what happens if you grease the pole.

A water consumption party. Apparently once a day, every one of the (roughly) billion butterflies has to make a trip to a water source. They look for the ones in direct sun. If the sun leaves, they immediately fly away, because without sun they do not have enough strength to fly back to their home in the trees.
