There are some interesting things to consider when building a birdhouse. For instance, the size of the entrance hole and height above the floor of the birdhouse is very important to appeal to the right species of bird. Also, the popular perch stick is just below the entrance hole is not needed, nor recommended. It provides a place for predators to sit and wait. Another feature to prevent hungry squirrels from chewing through the hole area is to reinforce the hole with a ¾” thick block of wood, making the entrance passage longer. All the specifications and suggestions you will need are on the internet.
