It is unfortunate that I am not getting any occupants in my birdhouse even since it was erected on a oak in the south west corner of my backyard. I used my kid's taekwondo breaking boards to build it. Painted it white. The entry hole is set at 1 inch. What am I doing wrong or is the color is offensive?

Picture 2 is the frontage of the birdhouse and picture 3 is the back of the birdhouse.
