I live in a NJ suburb so those solutions won't be feasible.
My kids might like the wooden owl idea though...
mike, I'm planning to try this:
If larger critters like birds and raccoons are getting to your corn, try wrapping duct tape around the ear an inch above the stalk and an inch below the tip
I also read somewhere that you could put a brown paper bag over the ears and tie it closed. Timing is "just as the silk begins to wilt". I'm going to try these methods if the squirrels or birds try to get at my corn. This is my first time growing corn so I don't know if these methods will work, however.
Also when I sowed my corn seeds (in May), I used floating row cover over fencing that's too small for blackbirds and grackles to get through in one area and covered row tunnels in another area until the corn outgrew them (about 18' tall). I'm not sure if doing this would make it too hot inside in your area at this time of the year. For me, it provided extra warmth for the corn so it worked out well.
