Q: Some creature is eating the kernels from my corn ears. Any ideas? 

A: My bet is that it is mice in your garden. If it were a squirrel or raccoon they would pull the stalks down to the ground. Set mousetraps baited with peanut butter around your garden. Cover each one with an overturned plastic pot. Put a stone under the edge of the pot so a mouse can crawl underneath to enjoy its final meal.
