Spring is here so I built a few birdhouses. Actually I built one new one and refurbished two others, all with scrap wood. Admittedly, they are not much to look at, but they meet all the latest recommended birdhouse dimensions and include all the latest recommended features. I’m not sure the birds care how the outside of their houses look.
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.
