After some research on the internet, I wrapped the pole with sheet metal (makes the pole harder to grip), put a vent collar around it to make any access to the box more difficult, and smeared the sheet metal wrapping with a mixture of petroleum jelly and hot sauce! You can see the mud spot on the bottom of the box, where the birds do not perch, as if perhaps a raccoon or other animal had tried to disturb the nest by breaking in. |

While watching the bluebird nest, I noticed in the open field next to it, that there was this small, very skinny coyote looking for food.
