Modular Bird House

A modular birdhouse based on the dutch bird protection guidelines (vogelbescherming). It features a changeable front that slides in from the side. This allows for the same birdhouse to accommodate different size holes for different birds while keeping the same birdhouse. Currently I have attached 1 front plate with a general sized hole. Feel free to add different sizes for different birds. The front slots in from the sides, but as there is no slot on the side there is a bit of wiggle room. As birds have yet to nest in my birdhouse I'm not sure if this is an issue.
