SECTION ONE: THE CONCEPT
In housing parrots outdoors there are many environmental problems to consider for their safety and comfort such as:  Weather (Heat, Cold, Wind and Rain), Disease Carrying Insects, Rodents, Varmints, Wild Birds, Snakes, Feral Cats.  This "do it yourself" e-handbook will explain how to do that with construction details shown in a pictorial fashion and in addition, explain how to protect the habitat itself from termite infestation and other environmental attacks. We will not give dimensions in most cases (except for wire etc.) because this concept can be used on any size scale and can even be built on wheels for maximum portability like the one below in Photo 1.  

Ultimate Outdoor Portable
Notice the solid bottom, solid top, raised removable wire floor, interior nest box and guillotine door in the front bottom center. (You fill the bottom with water and then open the door for flushing.) The removeable raised wire bottom prevents parrot escape while flushing out and keep the interior free of insects. The door must have a very good fit to hold water.
